The document discusses population trends and distribution in Pakistan. It notes that Pakistan has experienced rapid population growth accompanied by large-scale internal migration, resulting in uneven population distribution across the country. The study analyzes factors influencing population growth and distribution such as fertility, mortality, migration, and government policies. It evaluates the impacts of migration on urbanization and recommends long-term population distribution policies and regional planning to address over-concentration of populations in large cities.
The document discusses the demography and population of Pakistan. It defines population as all organisms that belong to the same species and live in the same area. Demography is defined as the study of human populations, including their size, composition, distribution, and how populations change over time through births, deaths, and migration. The population of Pakistan was reported at 163.77 million in 2009 and estimated at 179 million in 2012 according to the Population Census Organization. Rapid population growth and high fertility rates are linked to higher poverty levels.

This document provides demographic details about the world population and Pakistan. It defines demography and notes that the world population reached 7 billion in 2011. It then summarizes population growth trends in Pakistan, including that Pakistan has a population of over 187 million as of 2011. Several key demographic statistics about Pakistan are presented, such as population density, birth and death rates, urbanization rates, gender ratios, and literacy rates.
The document discusses the demographic transition model which describes the stages of population growth and change over time. It begins with Stage 1 characterized by high birth and death rates, leading to slow population growth. Stage 2 sees death rates decline while birth rates remain high, resulting in rapid population growth. Stage 3 is marked by falling birth rates as well as continuing declines in death rates, slowing population growth.
The document discusses human resources and population issues in Pakistan. It provides background on population growth rates, distribution, and causes of population explosion in Pakistan. Some key points are:
- Pakistan's population growth rate is 2.1% and it is the 6th most populous country, projected to become 4th largest by 2050.
- Factors driving high population growth include high birth rates, lack of education, early marriages, and preference for male children.
- The government needs to implement economic, social, family planning, and administrative measures to address overpopulation, such as modernizing agriculture, expanding industry, and creating rural job opportunities.

1) Pakistan's population has grown rapidly from 132 million in 1998 to an estimated 187 million in 2013, posing economic challenges for the country.
2) Rapid population growth is straining Pakistan's ability to provide adequate health, education, and job opportunities, and is exacerbating issues of poverty and unemployment.
3) Pakistan can reduce population growth by improving education, raising women's social and economic status, expanding family planning programs, and increasing job opportunities to lower fertility rates.
Overpopulation in Pakistan (Contemporary Issues) -ZKZareen Khan
The document discusses overpopulation as a threat to Pakistan. It notes that Pakistan's population is approximately 180 million people, straining resources and causing issues like poverty, pollution, and lack of adequate housing and healthcare. Overpopulation is driven by factors such as early marriages, high birth rates, a lack of family planning resources, and inconsistent government policies. Solutions proposed include promoting education, healthcare access, family planning programs, subsidizing public welfare, and raising awareness of the issue.

Demography is the scientific study of human populations. Key events in the history of demography include Ibn Khaldun's work in the 14th century, John Graunt producing the first life table in the 17th century, and John Snow mapping cholera deaths in London in the 19th century. Major population theories include Malthus' theory of unchecked population growth outstripping resources, Marx's view that population is controlled by economic factors, and the demographic transition theory of declining birth and death rates as countries develop. India's current population is over 1.2 billion with a growth rate of 17.6% in the last decade. Key demographic indicators of India include sex ratio, age composition, and dependency ratio.
The document defines key population terms and provides context about Pakistan's population. It discusses that Pakistan has a high population growth rate of 1.6% annually and an estimated population of over 170 million as of 2010, making it the 6th most populous country. It also summarizes Pakistan's population policy which aims to reduce growth rates through family planning initiatives, but faces challenges from social and cultural factors. Historical population data is presented showing Pakistan's population has increased over fourfold since 1951.
Demographic transition in India and its effectsSarinkumar P S
Population expansion around the world has shown a pattern of rapid increase, again stabilization and very small increase or decline after that. This trend is conceptualized as demographic transition. In the following presentation we will look at:

Pakistan has a rapidly growing population that is causing environmental and economic problems. The population growth rate is 1.573% annually, with a high birth rate of 24.81 births per 1,000 people and a lower death rate of 6.92 deaths per 1,000 people. Rapid population growth and high fertility rates contribute to high poverty levels. Overpopulation is caused by factors like early marriages, high birth rates, a desire for sons, and lack of family planning resources. It creates issues such as limited resources, pollution, unemployment, and increased crime.
Demography is the scientific study of human populations and includes changes in population size, composition, and distribution over time. There are 5 key demographic processes: fertility, mortality, marriage, migration, and social mobility. India currently has a population of over 1.2 billion people that is growing at a rate of 16 million per year. This puts pressure on resources and increases the dependency ratio. Literacy rates and life expectancy have increased over time but challenges remain, such as the low sex ratio resulting from female feticide and infanticide.
The document provides an overview of demography and key demographic concepts and trends in India. It defines demography as the scientific study of human populations, and notes that demographers study factors such as population size, composition, growth rates, and distribution. It then discusses components of population change like fertility, mortality, and migration. Some highlights of India's demography include a total population of over 1.27 billion, declining birth and death rates, and a projected population of 1.6 billion by 2050 when it will surpass China as the world's most populous nation. Key demographic indicators for India like its age-sex composition and sex ratio are also summarized.

India has a population of over 1.21 billion people as of 2010, making it the second most populous country in the world. The population is young, with 64.9% of people between the ages of 15-64. Literacy rates have increased but are still only 74% overall. The major religions are Hinduism and Islam. While the female sex ratio has improved slightly in recent decades, it remains unbalanced. Most Indians work in agriculture, but employment is growing fastest in the services sector. Income levels remain low, with per capita income of only around $1,200 USD.
The document discusses key concepts in demography including population growth rates, fertility rates, and factors influencing population trends. It notes that world population grew slowly until 1800 but has accelerated since then. Several South Asian countries now rank among the most populous globally. Factors like education, family planning services, and changes in marriage patterns have contributed to declining fertility rates in many countries. Common metrics used to measure fertility include crude birth rate, total fertility rate, and age-specific fertility rates. India's population growth rate increased in the early 20th century as death rates fell faster than birth rates.
Demographic trends in India show a population that is young, growing, and urbanizing. Key indicators include a total fertility rate declining from 5 children per woman in the 1980s to 2.3 today, resulting in a shift from a broad-based age pyramid to one with a bulging middle. However, India's population is projected to surpass China's and reach over 1.5 billion by 2050, bringing new challenges around rapid urbanization, education and employment opportunities for a large youth population.
Demography is the scientific study of human populations and their characteristics. It deals with five key demographic processes: size, distribution, structure, change (through births, deaths, and migration), and characteristics like ethnicity, economic status, and more. Data comes from sources like censuses, surveys, vital event registration, and demographic studies. India's population as of 2011 was over 1.2 billion, with a density of 382 per square km and urbanization increasing. Key indicators include crude birth rate, death rate, growth rate, sex ratio, dependency ratio, and life expectancy.
This document discusses population growth in India and its impact on economic development. It provides background on Trinity Institute of Professional Studies and covers topics like population trends in India from 1901 to 2011, causes of high birth and low death rates, how population affects factors like food production and unemployment, key demographic data on life expectancy, density, and rural/urban distribution. It also summarizes India's national population policies from 1951 to 2000 that aimed to lower birth rates and encourage family planning through education and incentives.
India is currently in Stage 2 of the Demographic Transition Theory. Stage 2 is characterized by a high birth rate that remains steady while the death rate is falling, leading to a steady rise in population. Some key indicators show India has a birth rate of 20.6 per 1000 people, death rate of 7.48 per 1000, natural population increase of 1.4% per year, and is experiencing declining birth and death rates. Overall, the document analyzes India's population trends according to the Demographic Transition Theory and determines India is in Stage 2 where birth rate is high but death rate is falling, causing steady population growth.
This document discusses population trends and family systems in Pakistan. It notes that Pakistan's population as of 2014 was 185 million, making it the 6th most populous country. The population pyramid is described as expansive, with a young and growing population. Women are described as playing a vital role in Pakistani society across fields and performing well. Family is considered the basic unit of society, with respect and honor as its foundation. Common family types in Pakistan include nuclear, joint, extended, and blended families.

- Pakistan has a population of 185.9 million with a growth rate of 1.6% and birth and death rates of 31/1000 and 8/1000 respectively.
- High population growth is due to early marriages, desire for sons, resistance to family planning and inconsistent government policies. Remedies include increasing the literacy rate, empowering women, and implementing population welfare programs.
- The majority of the labor force works in agriculture but migration to cities is increasing due to mechanization and lack of economic opportunities in rural areas. Unemployment remains a challenge due to high population growth and lack of skills training.
This document summarizes key concepts in demography and population trends in India. It discusses that nearly 3/4 of the world's population lives in developing countries. In India, the population reached 1 billion in 2000 and is growing by 16 million per year through births. The demographic cycle describes 5 stages of population growth from high stationary to declining rates. Current trends show India's population will reach 10 billion by 2050, with over 1 billion people in 2007. The population is aging with more elderly and fewer children. Literacy rates have improved but regional differences remain.
India's population has grown significantly over the past century and is projected to surpass China's population by 2050. Key points:
- India's population doubled from 361 million in 1951 to 846 million in 1991 and reached over 1.2 billion in 2011.
- The population growth rate has declined but population continues to rise rapidly due to the large youth population.
- India's age structure is characterized by a broad base and tapering top on age pyramids, indicative of developing countries with high birth rates.
- Sex ratios in India have historically been unfavorable to women and declined further over time, indicating a preference for male children.
This document summarizes key concepts in demography including:
- Demography deals with the study of population size, composition, behavior, and distribution in a given area and time.
- Population dynamics examines factors like marriage, births, deaths, and migration that influence population characteristics.
- Censuses collect social, economic, and demographic data on all individuals in a country and are typically conducted every 10 years.
- India's population has grown significantly over time from 20 crores in the first census of 1881 to over 100 crores currently, with increasing urbanization and a declining growth rate.
This document analyzes population trends in India using data from the 2011 census. It discusses key demography terms and examines registered births, deaths, and infant deaths from 2000 to 2009 for each state. Some main findings are that Maharashtra and Uttar Pradesh have the highest population growth, births declined along the decade, and the death rate drop has exceeded the birth rate drop leading to continued growth. Factors like education, family planning programs, and immigration affect population trends in each state.

This document discusses the demography and population of Pakistan. It provides statistics on Pakistan's current population size, population growth rates, birth and death rates, and population projections. It also examines population dynamics and causes of overpopulation in Pakistan. Additionally, it outlines the demographic characteristics of Pakistan's population, including ethnicity, religions, languages, age structure, literacy rates, education levels, health expenditures, and urbanization trends.
The document discusses population dynamics and demography. It covers several key topics:
1. Population is a dynamic field that has seen significant changes in birth rates and population trajectories globally in recent years.
2. Demographic factors like population size, growth, structure, and changes impact many aspects of life from housing to healthcare.
3. Global population is still rising by over 80 million per year and is expected to continue growing this century unless action is taken. The largest population growth will occur in sub-Saharan Africa.
Pakistan is experiencing a population crisis due to high population growth rates. The population of Pakistan was reported at 163.77 million in 2009 and is expected to reach 180.54 million in 2015. Rapid population growth is straining resources and contributing to poverty in Pakistan. Key factors driving population growth include early marriages, a high total fertility rate of 3.2 children per woman, a decreasing death rate, a desire for sons, and lack of family planning. Overpopulation is causing problems such as food and resource scarcity, unemployment, pollution, and health and housing issues.
The world population reached 7 billion in 2011 and is currently growing at a rate of around 1.11% per year, adding approximately 80 million people annually. Population growth peaked in the late 1960s at 2% per year. The global population is projected to reach 8.4 billion by 2030 and 9.6 billion by 2050 before stabilizing around 2050. There are currently slightly more men than women worldwide.
This online lesson discusses demographics and overpopulation in the Philippines. It begins by defining demography and describing how the Philippines census is conducted. Key points from the 2010 census are provided, such as the total population and regional breakdown. Factors contributing to overpopulation in the Philippines include declining death rates, better medical facilities, lack of family planning, and immigration. Effects of overpopulation include depletion of resources, environmental degradation, conflicts, unemployment, and increased cost of living. Solutions discussed include improving education, promoting family planning awareness, sex education, and providing tax benefits for smaller families.
Demography is the scientific study of human populations and changes over time. Demographers analyze population size, composition, distribution and growth/decline. They use tools like counts, rates, ratios and proportions to measure population characteristics like births, deaths, age, gender and location. Factors like fertility, mortality and migration impact population structure and density over time. High birth rates lead to younger population structures while lower death rates result in older populations. Migration patterns also influence the makeup of populations.
population dynamics and its definitionssrafiaimtiaz14
This document provides an introduction to concepts related to population dynamics and demography. It defines key terms like total fertility rate, mortality rates, population growth rate, and household size. It also presents data on Pakistan's historical population growth, noting it surpassed 200 million in 2017 and is the 5th most populous country. Figures show its population is projected to reach 330 million by 2050. The document concludes with information on Pakistan's provincial populations from the 2023 census, with Punjab having the largest at over 127 million people.
World population reached 7.5 billion in 2017 and is projected to continue growing, though more slowly, reaching 8 billion by 2025 and possibly 11 billion by 2100. The annual growth rate peaked in the 1960s at 2% but has since declined to about 1.1% currently. India has the second largest population in the world at over 1.2 billion according to the 2011 census, and its population is projected to surpass China's in the coming decades.
The document discusses key concepts related to population and demography. It defines population as the number of people living in a given area, and demography as the study of population size, distribution, composition, and changes. It then covers determinants of demographic trends like fertility, mortality, and migration. Fertility refers to birth rates and is influenced by factors like education and occupation. Mortality means death and is measured using rates like life expectancy. Migration involves moving between areas or countries.
The study deals different terms, concept, definitions, theories of population, census statistics, maps and diagrams for representations of demographic data. You read it carefully until the last.
This document discusses key concepts in demography and population statistics of Pakistan. It defines demography as the scientific study of human populations, focusing on birth rates, death rates, and migration. It then discusses Pakistan's current population size, growth rate, fertility rate, mortality rates, level of urbanization, and other population dynamics. The document also introduces concepts like population pyramids, the demographic transition, and the importance of social mobilization for addressing issues related to population growth.
The whole number of people or inhabitants in a country or region” -(Webster’s dictionary)
In sociology, population refers to a collection of human beings.
The document discusses population trends in India based on a presentation. It provides information on key population concepts like population distribution, growth rates, birth and death rates, age composition, sex ratio and literacy rates in India. Some key facts presented include that India's population in 2011 was 1.21 billion with the growth rate slowing to 17.64% in the past decade, half of India's population lives in 5 states, and the national population policy aims to reduce fertility rates and achieve population stability by 2045.
The world population distribution, density and growthAshaJegadeesan
The document discusses key topics related to world population including:
1. The current world population is 7.8 billion as of 2020 and is unevenly distributed across the world.
2. Population density varies based on factors like climate, resources, and level of development. densely populated areas have over 200 people per square km while sparsely populated areas have under 1 person per square km.
3. Population growth is influenced by birth rates, death rates, and migration patterns. Most countries have experienced a demographic transition from high birth/death rates to low birth/death rates as development increased.

The document discusses population growth and structure. It begins by outlining factors that affect population distribution and density, such as physical, social, economic and political influences. It then describes population concepts like birth rate, death rate, natural increase/decrease, and density. Models of population change are presented, including the demographic transition model and population pyramids. Population pyramids illustrate age and sex structures and can indicate development levels. Overpopulation causes and problems are also summarized.
Examination of a Global Population Issue.docxwrite4
The document discusses global population trends and issues. It notes that the world population is currently around 7.2 billion and is expected to reach 8.1 billion by 2025. Most growth is projected in developing regions, especially Africa. Factors like fertility rates, mortality rates, and migration influence population trends. Population growth can provide benefits like increased workforce and economic growth, but can also strain resources and the environment if not managed sustainably. International agreements have aimed to support voluntary family planning programs around the world.
The technology uses reclaimed CO₂ as the dyeing medium in a closed loop process. When pressurized, CO₂ becomes supercritical (SC-CO₂). In this state CO₂ has a very high solvent power, allowing the dye to dissolve easily.
The debris of the ‘last major merger’ is dynamically youngSérgio Sacani
The Milky Way’s (MW) inner stellar halo contains an [Fe/H]-rich component with highly eccentric orbits, often referred to as the
‘last major merger.’ Hypotheses for the origin of this component include Gaia-Sausage/Enceladus (GSE), where the progenitor
collided with the MW proto-disc 8–11 Gyr ago, and the Virgo Radial Merger (VRM), where the progenitor collided with the
MW disc within the last 3 Gyr. These two scenarios make different predictions about observable structure in local phase space,
because the morphology of debris depends on how long it has had to phase mix. The recently identified phase-space folds in Gaia
DR3 have positive caustic velocities, making them fundamentally different than the phase-mixed chevrons found in simulations
at late times. Roughly 20 per cent of the stars in the prograde local stellar halo are associated with the observed caustics. Based
on a simple phase-mixing model, the observed number of caustics are consistent with a merger that occurred 1–2 Gyr ago.
We also compare the observed phase-space distribution to FIRE-2 Latte simulations of GSE-like mergers, using a quantitative
measurement of phase mixing (2D causticality). The observed local phase-space distribution best matches the simulated data
1–2 Gyr after collision, and certainly not later than 3 Gyr. This is further evidence that the progenitor of the ‘last major merger’
did not collide with the MW proto-disc at early times, as is thought for the GSE, but instead collided with the MW disc within
the last few Gyr, consistent with the body of work surrounding the VRM.
The use of Nauplii and metanauplii artemia in aquaculture (brine shrimp).pptxMAGOTI ERNEST
Although Artemia has been known to man for centuries, its use as a food for the culture of larval organisms apparently began only in the 1930s, when several investigators found that it made an excellent food for newly hatched fish larvae (Litvinenko et al., 2023). As aquaculture developed in the 1960s and ‘70s, the use of Artemia also became more widespread, due both to its convenience and to its nutritional value for larval organisms (Arenas-Pardo et al., 2024). The fact that Artemia dormant cysts can be stored for long periods in cans, and then used as an off-the-shelf food requiring only 24 h of incubation makes them the most convenient, least labor-intensive, live food available for aquaculture (Sorgeloos & Roubach, 2021). The nutritional value of Artemia, especially for marine organisms, is not constant, but varies both geographically and temporally. During the last decade, however, both the causes of Artemia nutritional variability and methods to improve poorquality Artemia have been identified (Loufi et al., 2024).
Brine shrimp (Artemia spp.) are used in marine aquaculture worldwide. Annually, more than 2,000 metric tons of dry cysts are used for cultivation of fish, crustacean, and shellfish larva. Brine shrimp are important to aquaculture because newly hatched brine shrimp nauplii (larvae) provide a food source for many fish fry (Mozanzadeh et al., 2021). Culture and harvesting of brine shrimp eggs represents another aspect of the aquaculture industry. Nauplii and metanauplii of Artemia, commonly known as brine shrimp, play a crucial role in aquaculture due to their nutritional value and suitability as live feed for many aquatic species, particularly in larval stages (Sorgeloos & Roubach, 2021).
When I was asked to give a companion lecture in support of ‘The Philosophy of Science’ (https://shorturl.at/4pUXz) I decided not to walk through the detail of the many methodologies in order of use. Instead, I chose to employ a long standing, and ongoing, scientific development as an exemplar. And so, I chose the ever evolving story of Thermodynamics as a scientific investigation at its best.
Conducted over a period of >200 years, Thermodynamics R&D, and application, benefitted from the highest levels of professionalism, collaboration, and technical thoroughness. New layers of application, methodology, and practice were made possible by the progressive advance of technology. In turn, this has seen measurement and modelling accuracy continually improved at a micro and macro level.
Perhaps most importantly, Thermodynamics rapidly became a primary tool in the advance of applied science/engineering/technology, spanning micro-tech, to aerospace and cosmology. I can think of no better a story to illustrate the breadth of scientific methodologies and applications at their best.

Phenomics assisted breeding in crop improvementIshaGoswami9
As the population is increasing and will reach about 9 billion upto 2050. Also due to climate change, it is difficult to meet the food requirement of such a large population. Facing the challenges presented by resource shortages, climate
change, and increasing global population, crop yield and quality need to be improved in a sustainable way over the coming decades. Genetic improvement by breeding is the best way to increase crop productivity. With the rapid progression of functional
genomics, an increasing number of crop genomes have been sequenced and dozens of genes influencing key agronomic traits have been identified. However, current genome sequence information has not been adequately exploited for understanding
the complex characteristics of multiple gene, owing to a lack of crop phenotypic data. Efficient, automatic, and accurate technologies and platforms that can capture phenotypic data that can
be linked to genomics information for crop improvement at all growth stages have become as important as genotyping. Thus,
high-throughput phenotyping has become the major bottleneck restricting crop breeding. Plant phenomics has been defined as the high-throughput, accurate acquisition and analysis of multi-dimensional phenotypes
during crop growing stages at the organism level, including the cell, tissue, organ, individual plant, plot, and field levels. With the rapid development of novel sensors, imaging technology,
and analysis methods, numerous infrastructure platforms have been developed for phenotyping.

3. INTRODUCTION
Population distribution, including the process of
migration, has been studied for over a century, but the
complex inter-relationships between migration and
demographic, social, and economic factors have made
it difficult to analyze the phenomenon. Pakistan's rapid
population growth has been accompanied by large
scale internal migration resulting in the distribution of
population and subsequent undisciplined urbanization.
This study deals with some important aspects of
internal migration and uneven population distribution in
the country during the present century. The literature
review is followed by an analysis of population growth
and distribution, with emphasis on the role of
migration. The main sources of data are census
publications. Important determinants of the decision to
move, and the consequences of rapid urbanization are
4. To explain the existing population distribution pattern, a
critical evaluation of the impacts of various government
policies (both explicit and implicit) has also been
carried out in historical perspective. The study
recommends the adoption of specific long-term
population distribution policies to tackle the increasing
problems of over-concentration of population in a few
large cities of the country. These need to be
substantiated by national regional planning polices in
order to provide a basis for the nationalization of
regional plans, or for the reorganization of national
plans.

CONCLUSION
6. What is trend Distribution of
Population
Population distribution means the pattern of where people
live.
Places which are sparsely populated contain few people.
Places which are densely populated contain many people.
What is the population trend?
Population trend refers to changes over time and can
include changes in ranging behavior (e.g., distance and
route) and distribution, biogeography (e.g., size
of population) and life-history (e.g., birth and death rates).
7. What is Population?
A population is all the organisms
that both belong to the same group
or Species and live in the
same geographical area.
Populations may be relatively small
and closed, as on an island or in a
valley
8. What does Population actually means ???
In general , a term for the number of people
living in an area at a particular time .
How can Population Growth be defined ???
The change in population over time and can be
quantified as the change in number of
individuals in a population us “per unit time”.
The term Population Growth can technically
refer to any species , but almost refers to
humans and it is often informally , far the more
specific demographic term Population Growth
Rate.

10. What is Demography?
Demography is the study of human populations
(their size, composition and distribution across
place, and the process through which populations
change.
Births, deaths and migration are the ‘big three’ of
demography, jointly producing population stability
or change

25. In the absence of a conscious effort to control the size of families,
the larger the fraction of the population who are in the fertile age
range the more rapid will be the population growth, and this will
influence the average age of the population structure towards the
younger end of the spectrum.
Worldwide, there are significant differences between birth rates. A major study in the
1980s, carried out by the Population Division of the Department of International
Economic and Social Affairs of the UN Secretariat, studied the relationship between
population age and sex distribution and crude fertility rates for twenty one countries in
the developing world.
26. Birth Rate
The ratio of total live births to total
population in a specified community or
area over a specified period of time.
The birth rate is often expressed as the
number of live births per 1,000 of the
population per year.
Birth rate; crude (per 1;000 people) in
Pakistan was measured at 27.28 in
2010, according to the World Bank.
27. Pakistan sixth most populous country in
world: survey * Growth rate of population
during 2012-2013 is 2.0 percent
it is expected that Pakistan will attain fifth
position in the world in terms of total
population in 2050.

29. It is expected that the forecast bird 'flu epidemic will behave
similarly. War differentially reduces the proportion of younger
men. The majority of infectious diseases of early childhood
have been conquered by immunization, and improved nutrition
and hygiene have rendered childhood safer.
. The effect of this is to raise the population in the upper age groups
substantially. Women have high life expectancy than men wherever they
live. The down side of this is that the extended lives are often lived in
bad health, as the treatments people receive may keep them alive but
do little to ameliorate the underlying pain or disability brought on by the
diseases, and virtually nothing for the various forms of senile dementia
that are increasingly encountered.
30. Death Rate
Mortality rate is a measure of the
number of deaths (in general, or due to
a specific cause) in a population, scaled
to the size of that population, per unit of
time.
The total number of deaths As of July
2009 the crude death rate for the whole
world is about 8.37 per 1,000 per year
according to the current World
Factbook
31.
32. Migration is the movement
of people from one area to
another.
When people move into an
area its called emigration.
When people leave an area
its called emigration.
33. Migration
The simple definition of migration is
“The movement of people from one place to
another place”
34. “The figure for the difference between the
number of persons entering and leaving a
country during the year per 1,000 persons.
High levels of migration can cause
problems such as increasing
unemployment and potential ethnic strife (if
people are coming in) or a reduction in the
labor force, perhaps in certain key sectors
(if people are leaving).” accurate as of
December 6, 2013
35. Type of migration
First, internal migration, i.e. migration
within one country
Secondly international migration, which
means the movement from one country
to another.
36. Net migration in Pakistan was last
measured at -1999998 in 2010,
according to the World Bank.
-2 migrant(s)/1,000 population (2012
est.)
-1.84 migrant(s)/1,000 population (2013
est.)
Country comparison to the world: 160

38. 1947 migration from India
• No communication link
with KPK and
Baluchistan
• Compulsory migration
between India and
Pakistan’s punjab
• Migrants had a cultural
and linguistic link with
punjab
• Pakistan population
increased 6% (1.8m)
• No migration to KPK
and Baluchistan
• Migration increased in
Punjab - 90% to 192%
(1941-1951)
• Migration increased in
Sindh - >150% (1941-
1951)s
39. Reasons of migration
The reasons for migration can be
divided into two main aspects, the so-
called "push" and "pull" factors.
Push factors are those in their old place
which force people to move. For
example, there may be civil wars or
wars in general in the country, but
political or religious oppression, climate
changes, lack of jobs or simply poverty
are all important push factors.
40. Pull factors are factors in the target
country which encourage people to
move; these include peace and safety, a
chance of a better job, better education,
social security, a better standard of living
in general as well as political and
religious freedom.
41. Migration
Movement of people from one area to
another.
Types of migration
In-migration: people arriving in the area
from other places. (Immigrants)
Out-migration: People leaving the area
to go to other areas. (emigrants)
Migration can be internal, within a
country such as rural to urban.
42. Factors of rural-urban
migration.
Rural push
factors.
Urban pull
factors.
•Over population.
•Unemployment(mech
anization)
•Natural disasters like
flood.
•Pressure on land.
•Better employment.
•Good services such
as hospitals etc.
•Better quality of food.
•Better life standard.
44. Problems resulting from
Rural-Urban Migration
Housing
Problems:
Deterioration of living
conditions
Increased Health
hazards.
The rapid growth of
slums.
Environmental
Problems:
Air, water and land
pollution is caused by
high population in
urban areas.
Surface and ground
water is contaminated
by dumping of
industrial waste.
45. Out-Migration From
Pakistan
Developmental projects in the Middle East
attracted the skilled and unskilled laborers.
The glamorous lifestyle of the advanced
countries has attracted people.
High crime rates and terrorists activities in
Pakistan have created unrest among
people.
Depopulation in other countries like
Canada encourage emigrantssa from
Pakistan.
46. CONCLUSION
Hence, it is concluded that over population is a
threat for the stability and strengthening of any
nation.
So steps should be taken to aware the people
that if the families will be small than they can
enjoy their lives with all the facilities and the next
coming generation will be healthy and organized
due to the proper attention of parents.
Importance and advantages of small family
should be promoted in the newly married
couples and the girls who are about to get
married, because women health is also affected
with more children.
47. Education should be promoted in
small villages and towns.
So for a healthy family, healthy
mother and progressive society,
population control is the most
important aspect.
