Equity is the absence of avoidable, unfair, or remediable differences among groups of people, whether those groups are defined socially, economically, demographically or geographically or by other means of stratification. "Health equity” or “equity in health” implies that ideally, everyone should have a fair opportunity to attain their full health potential and that no one should be disadvantaged from achieving this potential.
The document discusses key concepts in population and demography including:
1. Population refers to a collection of human beings that share characteristics that can be analyzed. Population growth rate measures the increase in a population over a period of time.
2. Demography is the statistical study of human populations and how they change over time due to factors like birth, death, migration, and aging.
3. Thomas Malthus' theory proposed that population increases faster than the food supply, pushing people to the verge of starvation. The demographic transition model shows populations transitioning through stages of high then low birth and death rates.
Demography is the scientific study of human populations, including size, composition, distribution, and changes over time. Key aspects studied include fertility rates, mortality rates, migration patterns, population size and distribution, and how these influence and are influenced by socioeconomic factors. Population pyramids and dependency ratios are important demographic indicators used to analyze population age structures and support planning. Census data provides information on population numbers, characteristics, and trends over time that is vital for governments, businesses, and academics.
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.
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.
Morbidity has been defined as any departure, subjective or objective, from a state of physiological or psychological well-being. In practice, morbidity encompasses disease, injury, and disability.
This document defines demography and lists various demographic indicators used to measure population health. It discusses indicators for mortality like crude death rate and life expectancy.

This document discusses the triple burden of disease faced by many developing countries. It describes the triple burden as the coexistence of infectious diseases, undernutrition, and emerging non-communicable diseases. Many countries now struggle with this combination of communicable diseases, malnutrition, and non-communicable diseases like heart disease and diabetes. Addressing this triple burden presents challenges for healthcare systems in developing nations. Risk factors like poverty, malnutrition, urbanization and changing lifestyles have contributed to the rise of non-communicable diseases.
This document discusses definitions and concepts in epidemiology. It provides historical definitions of epidemiology from various scholars and outlines key aspects including disease frequency, distribution, and determinants. Descriptive epidemiology is introduced as the initial phase of epidemiological investigation that describes disease occurrence in terms of time, place, and person. Key measures like incidence, prevalence, rates, and ratios are also defined.
Demography is the scientific study of human populations, including their size, composition, and distribution over time and space. It involves analyzing populations based on factors like births, deaths, and migration patterns. Key aspects of demography include population composition, density, urbanization rates, literacy and education levels, and life expectancy. Understanding changes in demographics can help policymakers plan for issues like healthcare needs and disease prevention. India's population has grown steadily since 1921 and is projected to exceed 1.53 billion by 2050.
This document discusses public health problems and outlines criteria for determining priority public health issues. It defines key terms like health, disease, illness, and ill health. Public health aims to prevent disease through organized community efforts. Demands on health care exceed resources due to factors like population growth, aging, and unhealthy environments. Priority public health problems are determined by prevalence, individual impact, societal impact, and potential for prevention/treatment. The document concludes that governments should implement policies to reduce population growth, increase health sector resources, and encourage individual health maintenance.
Measures of mortality provide important information for epidemiological studies. They include crude death rate, specific death rates, case fatality rate, proportional mortality rate, and survival rate. Standardized rates allow for comparisons between populations with different age compositions. Some challenges include incomplete reporting, inaccurate information, and non-uniformity across locations. However, mortality measures are useful for explaining trends, prioritizing health issues, designing interventions, and assessing public health programs.
Epidemiology is the study of disease distribution and determinants in populations. Descriptive epidemiology involves describing disease patterns, while analytical epidemiology tests hypotheses about disease determinants. A case-control study compares exposures in individuals with (cases) and without (controls) a disease to identify potential risk factors. It proceeds backwards from effect to cause by first identifying cases and then finding controls to measure past exposures, which are then analyzed using measures like odds ratios.
This document provides an introduction to key concepts in public health including definitions, major issues, and the history of public health. It discusses how public health differs from clinical medicine by focusing on populations rather than individual patients. Public health aims to prevent disease and injury through community-level interventions and policy changes. The document also summarizes a famous case study where the physician John Snow used epidemiological methods to identify contaminated water as the source of a cholera outbreak in London in the 1850s.
Demography is the statistical study of human populations, including their size, structure, and changes. It analyzes populations through factors like births, deaths, and migration.

Methods for measuring these processes are also outlined, such as crude birth/death rates.
Vital statistics related to maternal health in indiaPriyanka Gohil
This topic contains introduction of vital statistics, list of important statistics, birth rate, death rate, specific death rates, infant mortality rate, neonatal mortality rate, under five mortality rate, maternal mortality rate (detailed), perinatal mortality rate (detailed), expectation of life, general fertility rate and still births.
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.
The document discusses infant mortality rate (IMR), which is the number of infant deaths per 1000 live births. It has significantly declined in modern times due to improved healthcare. IMR correlates with a country's development level and is used as a standard of living indicator. However, calculation methods vary between countries. Common causes of infant mortality include low birth weight, respiratory issues, SIDS, and lack of essentials. IMR can be reduced through initiatives aimed at improving literacy, healthcare access, and reducing high-risk behaviors.
This document summarizes a case study on infant mortality rate (IMR) and malnourishment in Satna, Madhya Pradesh, India. It begins with definitions of IMR from organizations like UNICEF and WHO. It then provides background on worldwide and Indian IMR trends, noting that Satna has a higher IMR than most other Indian states and countries globally. The document describes conducting surveys of local officials and residents in Satna to understand factors contributing to high IMR and malnourishment. Key factors identified include lack of access to healthcare, sanitation issues, and poverty. The document concludes by suggesting steps like improving nutrition programs and healthcare access to help reduce IMR and malnourishment in Satna.
This document discusses factors that influence population fertility rates. It defines key terms used to measure fertility, including crude birth rate, general fertility rate, and total fertility rate.

The kidneys filter waste from the bloodstream and regulate water, electrolyte, and acid-base balance. They remove urea and other waste through urine while producing hormones like erythropoietin and renin. The kidneys contain nephrons which filter blood in the glomerulus and reabsorb nutrients in the tubules. Urine is transported by the ureters to the bladder, then exits through the urethra. The urinary system develops from intermediate mesoderm through pronephros, mesonephros, and metanephros stages, with the metanephros becoming the adult kidneys.
This document discusses multiparametric MRI and its use in guiding prostate biopsies. It provides information on anatomic, diffusion-weighted, and dynamic contrast-enhanced MRI and how they help visualize prostate tumors with high sensitivity and specificity. It then describes different approaches to targeted prostate biopsies using MRI information, including cognitive fusion, software-based fusion, and in-bore fusion biopsies. It discusses limitations and advantages of each method and concludes that while targeted biopsies improve cancer detection, mapping biopsies supplemented with targeted biopsies remain the standard for identifying clinically significant tumors.
Renal cell carcinoma accounts for approximately 3% of adult solid malignancies in the US, with over 51,000 new cases and 12,900 deaths annually. It arises from renal tubular epithelium and includes several subtypes associated with different genetic mutations and prognoses. Surgery is the main treatment for localized disease, while advanced or metastatic renal cell carcinoma has a poor prognosis despite newer targeted therapies and immunotherapies that have improved outcomes.
The major components of the male reproductive system are the testes, epididymis, ductus deferens, and ejaculatory duct on each side. The scrotum contains the testes and is divided into two compartments. The testes develop in the abdomen and descend into the scrotum before birth. Within the testes are seminiferous tubules that produce sperm. The epididymis is a coiled duct that courses along the testes where sperm mature. Blood flows into the testes via the testicular artery and drains via the testicular veins. The penis contains three cylinders of erectile tissue and transmits semen and urine.
This document provides information about testicular tumors including presentation, risk factors, classification, staging, and treatment. It begins with an introduction stating that testicular cancer is the most common malignancy in males aged 15-35. It then discusses signs and symptoms, risk factors such as cryptorchidism and family history, tumor markers, patterns of spread, staging classifications, and treatment options based on stage for both seminomas and non-seminomas. Treatment may involve surgery, radiation therapy, chemotherapy, lymph node dissection, and surveillance depending on tumor type and stage. Prognosis has improved significantly over time with overall 5-year survival rates now over 95% due to advances in diagnosis and treatment.
This document summarizes key points about vesicoureteral reflux (VUR):
- VUR is retrograde flow of urine from the bladder to the upper urinary tract and is more common in females under 5 years old. It can be primary due to UVJ deficiency or secondary to bladder issues.
- VUR is graded I-V based on VCUG findings. Low grade (I-III) often resolves spontaneously while high grade (IV-V) is less likely to without intervention. Treatment involves watchful waiting with antibiotics or surgical correction.

Wilms tumor, also known as nephroblastoma, is the most common renal tumor of childhood. It has an annual incidence of 7.6 cases per million children under 15 years old. Treatment involves surgery to remove the tumor along with chemotherapy and sometimes radiation therapy in a multimodal approach. The goal is to remove the tumor bulk surgically while using chemotherapy to eliminate any micrometastases in order to cure the cancer. Protocols vary depending on factors like age, tumor stage and histology, but generally include either surgery followed by chemotherapy or neoadjuvant chemotherapy before surgery, with excellent long-term survival rates with modern therapies.
Bladder injuries can occur from trauma or medical procedures and range from extraperitoneal to intraperitoneal. Extraperitoneal injuries make up 70% of cases and are often associated with pelvic fractures, while intraperitoneal injuries expose the bladder more directly. Clinical signs include hematuria, pelvic pain, and inability to catheterize. Diagnosis involves cystography to detect contrast leakage. Treatment depends on the severity and location of the injury, with uncomplicated extraperitoneal injuries often managed conservatively with catheter drainage and complicated or intraperitoneal injuries typically requiring surgical repair.
This document discusses urethral trauma, including classification, etiology, clinical manifestations, investigations, and principles of management. It separates discussions of posterior and anterior urethral injuries. For posterior injuries, immediate suprapubic cystostomy is standard, while delayed reconstruction is typically done via open posterior urethroplasty after 3 months. Anterior injuries may be treated with catheter diversion or primary realignment, while anastomotic urethroplasty is preferred for obliterated bulbar urethras after several weeks.
The rigid cystoscope and its accessories are described. Key components include the cystoscope sheath, bridges, obturators, and telescopes. The cystoscope sheath comes in different sizes measured in French and is used to intoduce the rigid cystoscope into the bladder. Bridges connect the sheath to the telescope and may have one or two accessory channels. Obturators are specific to each sheath size and make the tip smooth for insertion. Telescopes have different viewing angles and are classified by this. The document outlines the parts and uses of these rigid cystoscope components.
Urinary stones are the third most common problem of the urinary tract. Stone formation is a complex process that depends on the interaction of urinary concentration of ions, pH, flow rate, and inhibitors. Crystallization, crystal growth, aggregation, and adherence to the epithelium are required steps. Urine must be supersaturated for stones to form, but supersaturation alone is insufficient due to urinary inhibitors like citrate, magnesium, and glycoproteins. Common calcium stones may originate from subepithelial plaques that serve as anchors for stone growth.
Post-obstructive diuresis occurs after relief of a urinary tract obstruction, where large amounts of salt, water, and urea are excreted in the urine. It is caused by accumulation of fluids and solutes during obstruction and impairment of tubular reabsorption capabilities. Risk factors include edema and azotemia. The pathophysiology involves derangements in urinary concentrating ability due to disrupted aquaporin channels and sodium transport, as well as insensitivity to ADH. Treatment focuses on complete relief of obstruction, fluid replacement, electrolyte correction, and monitoring.
The kidney has several important functions including regulating blood pressure, fluid balance, and blood pH. The basic structural and functional unit of the kidney is the nephron, which filters blood to form urine. Each nephron contains a glomerulus for blood filtration and tubules (proximal tubule, loop of Henle, distal tubule, collecting duct) for reabsorption and secretion. Filtration occurs due to blood pressure gradients, with most filtrate reabsorbed along the nephron. The kidneys also produce hormones like renin, prostaglandins, and erythropoietin to help regulate blood pressure, red blood cell production, and other processes.
Anaphylaxis is a severe, life-threatening allergic reaction caused by the sudden release of mast cell and basophil mediators. It can be triggered by IgE-mediated or non-IgE mediated mechanisms. Common triggers include medications like antibiotics and contrast dyes, as well as stings, foods and latex. Symptoms affect multiple organ systems like the skin, respiratory and cardiovascular systems. Treatment involves stopping the trigger, supportive care, and medications like epinephrine, antihistamines and corticosteroids. Patients require monitoring for 24 hours due to risk of recurrence or delayed reactions.

ABDOMINAL TRAUMA in pediatrics part one.drhasanrajab
Abdominal trauma in pediatrics refers to injuries or damage to the abdominal organs in children. It can occur due to various causes such as falls, motor vehicle accidents, sports-related injuries, and physical abuse. Children are more vulnerable to abdominal trauma due to their unique anatomical and physiological characteristics. Signs and symptoms include abdominal pain, tenderness, distension, vomiting, and signs of shock. Diagnosis involves physical examination, imaging studies, and laboratory tests. Management depends on the severity and may involve conservative treatment or surgical intervention. Prevention is crucial in reducing the incidence of abdominal trauma in children.

Recomendações da OMS sobre cuidados maternos e neonatais para uma experiência pós-natal positiva.
Em consonância com os ODS – Objetivos do Desenvolvimento Sustentável e a Estratégia Global para a Saúde das Mulheres, Crianças e Adolescentes, e aplicando uma abordagem baseada nos direitos humanos, os esforços de cuidados pós-natais devem expandir-se para além da cobertura e da simples sobrevivência, de modo a incluir cuidados de qualidade.
Estas diretrizes visam melhorar a qualidade dos cuidados pós-natais essenciais e de rotina prestados às mulheres e aos recém-nascidos, com o objetivo final de melhorar a saúde e o bem-estar materno e neonatal.
Uma “experiência pós-natal positiva” é um resultado importante para todas as mulheres que dão à luz e para os seus recém-nascidos, estabelecendo as bases para a melhoria da saúde e do bem-estar a curto e longo prazo. Uma experiência pós-natal positiva é definida como aquela em que as mulheres, pessoas que gestam, os recém-nascidos, os casais, os pais, os cuidadores e as famílias recebem informação consistente, garantia e apoio de profissionais de saúde motivados; e onde um sistema de saúde flexível e com recursos reconheça as necessidades das mulheres e dos bebês e respeite o seu contexto cultural.
Estas diretrizes consolidadas apresentam algumas recomendações novas e já bem fundamentadas sobre cuidados pós-natais de rotina para mulheres e neonatos que recebem cuidados no pós-parto em unidades de saúde ou na comunidade, independentemente dos recursos disponíveis.
É fornecido um conjunto abrangente de recomendações para cuidados durante o período puerperal, com ênfase nos cuidados essenciais que todas as mulheres e recém-nascidos devem receber, e com a devida atenção à qualidade dos cuidados; isto é, a entrega e a experiência do cuidado recebido. Estas diretrizes atualizam e ampliam as recomendações da OMS de 2014 sobre cuidados pós-natais da mãe e do recém-nascido e complementam as atuais diretrizes da OMS sobre a gestão de complicações pós-natais.
O estabelecimento da amamentação e o manejo das principais intercorrências é contemplada.
Recomendamos muito.
Vamos discutir essas recomendações no nosso curso de pós-graduação em Aleitamento no Instituto Ciclos.

Introduce the basics of fertility, mortality and
morbidity and their measures
Discuss determinants of fertility
Describe population composition
3. Describe types of population
profiles

4. Resources:
Population Handbook, 4th International Edition,
2000.
Jordan Population and Family Health Surveys for the
years 1997, 2002.
Empowering women , developing society: female
education in the MENA
Population trends and challenges in the MENA
region
5. Demography
Demography ( population studies) is
the study of human populations: their
size, composition, and distribution as
well as the causes and consequences
of changes in these characteristics.
6. Three major factors determine the population
dynamics of a population:
Births ( fertility)
Deaths ( mortality)
Migration
If some groups within a population grow or
decline faster than others, the composition of the
whole is altered. These three factors determine
the most basic characteristics of a population, as
well as its demographic future.
7. Fertility
The number of births that occur to an individual
or in a population
In 1998, fertility rates of national populations
ranged from an average of 1.2 children per woman
in Italy, Latvia , Spain, and several other European
countries to 7.4 children per woman in the West
African country of Niger.
In US average was 2.0
For the world it is 2.9
8. Fecundity
The physiological ability of individuals or couples
to have children.
Some are infecund due to disease or genetic
dysfunction.
Mothers could be infecund when they breastfeed.
For individuals fecundity ranges between 0-30
children.
9. Factors accounting for fertility fecundity
gaps
There are usually gaps between fertility and fecundity.
What are the factors that may account for the gaps:
Cultural, economic, and health factors interfere with
the process of human reproduction.
Cultural values e.g. ( Does the society value large or
small families?)
10. Factors accounting for fertility fecundity
gaps
Social roles: ( Is the wife primarily a childbearer or a
childrearer ?)
Economic ( Do parents rely on children to look after
them in old age?)
Health (e.g what is the prevalence of gonorrehea in a
population ), that will impair fecundity.
11. Intermediate determinants of fertility
Cultural and economic factors affect fertility levels
indirectly: intermediate variables
They operate in different societies. The relative
importance of the factors vary by society.
12. Intermediate factors affecting fertility
Fecundity:
Ability to have intercourse
Ability to conceive
Ability to carry pregnancy to term
Sexual unions: % of women in union.
This rate is affected by other demographic factors such as:
The formation and dissolution of unions ( marriage,
divorce…etc)
Age at first marriage
Time spent outside the union…etc
Male mortality levels
14. Proximate determinants of fertility
John Bonnagartes demonstrated that 4 of these
variables explain nearly all variation in fertility
levels among population. These have a direct
biological effect on fertility:
The proportion of women married or in a
sexual union
The % of women using contraception
The proportion of women who are
breastfeeding/ infecund
The level of induced abortion
15. Fertility Proximate determinants
In US. and most developed countries
contraceptive use and abortion are the most
important proximate determinants. The rate of
contraceptive use in US, Brazil, Australia, and few
East and South East Asia have contraceptive use
rates of >= 75%.
Spain recorded the lowest fertility rate in a
nation 1.15 births per woman of rep age. Basically
due to 72% using contraceptives. Russia achieved
low fertility rates due to having easier access to
abortion.
16. Proximate determinants
When contraceptive and abortion prevalence rates
are low, the postpartum infecundity and marriage
determinants are more important.
African countries:
women marry early and bring more children, but they
breast feed for 2-3 years, thus prolonging the period of
infecundity following childbirth.
17. Proximate determinants
Others abstain as long as women are
breast feeding.
Polygamy and being away form home
Sexually transmitted diseases affect
fecundity.
18. Fertility Measurement
Birth Rate
The birth rate (also called the
crude birth rate)
It is the most easily obtained and
most common reported Definition:
It gives the average annual number of
births during a year per 1,000 persons
in the population at midyear;
19. The birth rate is usually the
dominant factor in determining
the rate of population growth.
It depends on both the level of
fertility and the age structure of
the population.
20. Fertility Measurement
Crude Birth Rate
There were 24 births per 1,000 population in Kuwait in
1994 :
Number of births (38,868) divided by the Total
population (1,620,086 ) x K (1,000 )= 24.0
In Jordan it is 26.79 est. 2011.
21. Around the world, birth rates vary widely.
In Western Sahara’s, a very high birth rate 47 per
1,000 in 1996, while
Italy’s it is very low, 9 per 1,000, also in 1996,
22. Fertility Measurement
General Fertility Rate
The general fertility rate GFR, (also called the
fertility rate) ,is the number of live births per
1,000 women ages 15-49 in a given year.
The GFR is a somewhat more refined measure than
the birth rate because it relates births to the age-sex
group at risk of giving birth (usually defined as
women ages 15-49).
23. General Fertility Rate
The GFR sums up, in a single number, the fertility
of all women at a given point in time.
Yemen’s general fertility rate in the early 1990s
was 238 live births per 1,000 women ages 15-49—
( 34 yrs) one of the highest in the world. (TFR =7)
The Czech Republic’s, it was very low at a rate of
34 per 1,000 women aged 15-49 in 1996. (TFR = 1)
24. Total Fertility Rate
The total fertility rate (TFR) is the average number
of children that would be born to a woman by the
time she ended childbearing if she were to pass
through all her childbearing years conforming to
the age-specific fertility rates of a given year.
25. Total Fertility Rate ( TFR(
It is the average number of children in a family.
Used to compare fertility among countries
It tracks changes in fertility over time
TFR in Jordan 3.6 ( JPFHS report, 2007)
Close to the (TFR) 3.7 (DHS report 2002)
28. Mortality
Death Rate: Definition: It is the average
annual number of deaths during a year per
1,000 population at midyear; also known as
crude death rate. The death rate, while
only a rough indicator of the mortality
situation in a country, accurately indicates
the current mortality impact on population
growth.
29. Crude Death Rate
In the early 1990s, the death rate in Turkey was 6.6 per
1,000 population.
Number of deaths (405,000 )/ Total population
(61,644,000) x K (1,000) = 6.6
In the early 1990s, Guinea’s death rate was 20 per 1,000
population, while Singapore’s was 5 per 1,000.
In Jordan 2.69 deaths/1,000 population (July 2011 est.)
30. This indicator is significantly affected
by age distribution, and most
countries will eventually show a rise in
the overall death rate, in spite of
continued decline in mortality at all
ages, as declining fertility results in an
aging population.
34. Infant Mortality Rate
Definition: This entry gives the
number of deaths of infants under
one year old in a given year per 1,000
live births in the same year; included
is the total death rate, and deaths by
sex, male and female. This rate is
often used as an indicator of the level
of health in a country.
35. Examples
There were 17 deaths of infants under age 1 per 1,000 live
births in Venezuela in 1996.
Number of deaths of infants under age 1 in a given
year (10,016) / Total live births in that year (595,816) x
K (1,000 )= 16.8
In 1996, Sweden reported the world’s lowest infant
mortality rate, 3.5 per 1,000. A high national rate would
be Malawi’s, which was estimated at 140 per 1,000 in
1997.
Latest figure about IMR in Jordan is 22/1000 live births
( DHS /2003) and 19 (JPFHS 2007)
36. Maternal Mortality Ratio
The maternal mortality ratio is the number of
women who die as a result of complications of
pregnancy or childbearing in a given year per
100,000 live births in that year.
Deaths due to complications of spontaneous or
induced abortions are included.
a maternal death is defined as the death of a
woman while pregnant or within 42 days of
termination of pregnancy from any cause related
to or aggravated by the pregnancy or its
management but not from accidental or
incidental causes.
37. Maternal Mortality Ratio
This measure is sometimes referred to as the
maternal mortality rate
There were 13 maternal deaths per 100,000 live births
in Russia in 1994.
Number of maternal deaths (185 )divided by Total live
births (1,408,159 )x K (100,000 )= 13.1
38. Life Expectancy
Life expectancy is an estimate of the average number of
additional years a person could expect to live if the age-
specific death rates for a given year prevailed for the rest
of his or her life.
Life expectancy is a hypothetical measure because it is
based on current death rates and actual death rates
change over the course of a person’s lifetime.
Each person’s life expectancy changes as he or she grows
older and as mortality trends change.
39. Life Expectancy
If the age-specific death rates for 1996 remain
unchanged, males in Brazil born in 1998 can
expect to live 64.1 years on average; females can
expect to live 70.6 years.
Life expectancy for Jordanian 72.9 in 2009.(world
bank indicators)
40. Population Composition
Age and Sex Composition
Age and sex are the most basic characteristics of a
population.
Every population has a different age and sex
composition— the number and proportion of
males and females in each age group—
This structure can have considerable impact on
the population’s social and economic situation,
both present and future.
41. Population Composition
Age and Sex Composition
Populations could be relatively young / developing
countries, About 40 % less than 15 years e.g. Africa..
Jordan . Less than 4% are older groups.
Relatively old populations ( aging), developed
countries, more than 10% over 65 years e.g. Europe/
Less than 25% of pop less than 15 years.
42. Age and Sex Composition
Young and old populations have markedly different
age compositions; as a consequence, they also have
different proportions of the population in the labor
force or in school, as well as different medical needs,
consumer preferences, and even crime patterns.
43. Median Age
A population’s age structure has a great deal to do with how
that population lives.
The median age is the age at which exactly half the
population is older and half is younger.
Examples:
The median age of the Costa Rican population in
1995 was 23 years.
In 1995, the median age in Jordan, with a young
population, was 18,
While that in Sweden was 38, signifying an older
population.
44. Sex Ratio
The sex ratio is the ratio of males to females in
a given population,
usually expressed as the number of males for
every 100 females.
The sex ratio at birth in most countries is about
105 or 106 males per 100 females.
After birth, sex ratios vary because of different
patterns of mortality and migration for males and
females within the population.
45. Population Pyramid
A population pyramid graphically displays a
population’s age and sex composition.
Horizontal bars present the numbers or proportions
of males and females in each age group.
The sum of all the age-sex groups in the population
pyramid equals 100 percent of the population.
48. Population profiles
Populations of countries can differ markedly as a result of
past and current patterns of fertility, mortality, and
migration. However, they all tend to fall into three
general profiles of age-sex composition.
1. Rapid growth is indicated by a pyramid with a large
percentage of people in the younger ages.
2. Slow growth is reflected by a pyramid with a smaller
proportion of the population in the younger ages.
3. Zero growth or decreasing populations are shown by
roughly equal numbers of people in all age ranges,
tapering off gradually at the older ages.
52. Population change
Population change has three components: births,
deaths, and migration.
As people are born, die, or move, their total numbers
in an area change.
During most of history, world population increased
very slowly, but during the 20th century, this growth
has accelerated.
53.
54. How do populations change?
A change in population size over a
given period of time equals the
number of people in the population
at the beginning of the period plus
any births that occur during the
period, minus any deaths, plus net
migration during the period.
56. Rate of Natural Increase
The rate of natural increase is the rate at which a
population is increasing (or decreasing) in a given
year due to a surplus (or deficit) of births over deaths,
expressed as a percentage of the base population.
Net migration is the number of immigrants minus
emigrants.
57. Growth Rate
The growth rate is the rate at which a population
is increasing (or decreasing) in a given year due to
natural increase and net migration, expressed as a
percentage of the base population.
The growth rate takes into account all
components of population growth: births, deaths,
and migration.
It equals ( births – deaths )+_ net migration/
total population X K ( 100).
It should never be confused with the birth rate,
but it sometimes is.
58. Population change
The change in population size accounted for by more
births in the population than deaths is referred to as
"natural increase."
The term "natural decrease" refers to population
decline resulting from more deaths than births.
59. Growth Rate
With an annual growth rate of 1.82 percent in 1996, the
United Arab Emirates would require about 38 years to
double its population.
Uganda would take 24 years, at 2.9 percent.
Belgium, at its present low annual growth rate of 0.5
percent, would take several centuries to double its
population.
Jordan :
Growth rate 2.8
Natural growth: 2.3
60. The Demographic Transition
The demographic transition refers to the change that
populations undergo from high rates of births and
deaths to low rates of births and deaths.
High levels of births and deaths kept most
populations from growing rapidly throughout most
of time.
61. The Demographic Transition
The decline in mortality usually precedes the decline
in fertility, resulting in population growth during the
transition period.
62.
63.
64. International Population Conferences
1974 Bucharest conference
In 1984, 149 nations participated in the
International Conference on Population, held in
Mexico City.
Representatives from over 180 countries and 1,200
nongovernmental agencies convened in Cairo,
Egypt, for the United Nations International
Conference on Population and Development
(ICPD) in 1994.
65. Population policies
National population commissions were formed in
different countries
They formulated national population policies and
action plans
One major component of the action plan deals
with reproductive health
Reproductive health in the context of population
includes reproductive rights, sexuality, family
planning, reproductive morbidity, violence
against women, gender based differences, male
involvement in reproductive health.
