Demography is the study of human populations, including their size, makeup, economics, and social structure. Demographers group countries into developed and developing categories and use tools like age structure graphs, survivorship curves, and fertility/migration rates to analyze population changes over time and make predictions. All human populations are undergoing a demographic transition from high birth and death rates to lower rates as countries develop.
population development and environment is not directly linked but yet there is a indirect complex relationship between population development/ activities and environment for example urbanization, slums , mega cities emerge and the use of natural resources mush faster then they replanish
population development and environment is not directly linked but yet there is a indirect complex relationship between population development/ activities and environment for example urbanization, slums , mega cities emerge and the use of natural resources mush faster then they replanish
1) To know how countries pass through different stages of population growth as shown in the five stages of the Demographic Transition Model (birth rate, death rate and natural population changes) and how it changes population structure
2) To understand the impact of increasing urbanisation, agricultural change, education and the emancipation of women on the rate of population growth
3. To know how to construct a population pyramid
4. To understand how to interpret population characteristics from a pyramid and how to predict likely future changes in a population.
The world’s population is more than three times larger than it was in the mid-twentieth century. The global human population reached 8.0 billion in mid-November 2022 from an estimated 2.5 billion people in 1950, adding 1 billion people since 2010 and 2 billion since 1998. The world’s population is expected to increase by nearly 2 billion persons in the next 30 years, from the current 8 billion to 9.7 billion in 2050 and could peak at nearly 10.4 billion in the mid-2080s.

A tale of scale & speed: How the US Navy is enabling software delivery from l...sonjaschweigert1
Rapid and secure feature delivery is a goal across every application team and every branch of the DoD. The Navy’s DevSecOps platform, Party Barge, has achieved:
- Reduction in onboarding time from 5 weeks to 1 day
- Improved developer experience and productivity through actionable findings and reduction of false positives
- Maintenance of superior security standards and inherent policy enforcement with Authorization to Operate (ATO)
Development teams can ship efficiently and ensure applications are cyber ready for Navy Authorizing Officials (AOs). In this webinar, Sigma Defense and Anchore will give attendees a look behind the scenes and demo secure pipeline automation and security artifacts that speed up application ATO and time to production.
We will cover:
- How to remove silos in DevSecOps
- How to build efficient development pipeline roles and component templates
- How to deliver security artifacts that matter for ATO’s (SBOMs, vulnerability reports, and policy evidence)
- How to streamline operations with automated policy checks on container images

Removing Uninteresting Bytes in Software FuzzingAftab Hussain
Imagine a world where software fuzzing, the process of mutating bytes in test seeds to uncover hidden and erroneous program behaviors, becomes faster and more effective. A lot depends on the initial seeds, which can significantly dictate the trajectory of a fuzzing campaign, particularly in terms of how long it takes to uncover interesting behaviour in your code. We introduce DIAR, a technique designed to speedup fuzzing campaigns by pinpointing and eliminating those uninteresting bytes in the seeds. Picture this: instead of wasting valuable resources on meaningless mutations in large, bloated seeds, DIAR removes the unnecessary bytes, streamlining the entire process.
In this work, we equipped AFL, a popular fuzzer, with DIAR and examined two critical Linux libraries -- Libxml's xmllint, a tool for parsing xml documents, and Binutil's readelf, an essential debugging and security analysis command-line tool used to display detailed information about ELF (Executable and Linkable Format). Our preliminary results show that AFL+DIAR does not only discover new paths more quickly but also achieves higher coverage overall. This work thus showcases how starting with lean and optimized seeds can lead to faster, more comprehensive fuzzing campaigns -- and DIAR helps you find such seeds.

Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).

2. WHAT IS DEMOGRAPHY?
Demography- study of
populations, especially
human populations.
Includes study of:
Historical size of
population
Make up of population
Economics
Social structure
Demographers use this
info. to make
comparisons &
predictions about
populations.
3. WHAT 2 CATEGORIES DO DEMOGRAPHERS
GROUP COUNTRIES INTO?
Developed Countries
1.
Have higher avg. incomes
Slower pop. growth
Diverse industrial
economies
Ex: US, western Europe
4. WHAT 2 CATEGORIES DO DEMOGRAPHERS
GROUP COUNTRIES INTO?
Developing Countries
2.
Lower avg. incomes
Simple, agricultural
based economies
Rapid population growth
Ex: India, China,
countries in Africa
5. HOW HAS THE HUMAN POPULATION CHANGED
OVER TIME?
Population grew slowly
for 1000’s of years
In 1800’s (Modern Age)
population grew
exponentially
Due to increase in food
supply & better hygiene
thanks to industrial &
scientific revolutions
Human population
continues to grow
exponentially… will it
ever reach its carrying
capacity?
6. HOW CAN A POPULATION BE PREDICTED?
Demographers look at
many properties of
populations to predict:
Will community need
more schools?
Will community need
more retirement homes
Will population increase
to point where we need
more roads & utilities?
7. HOW CAN A POPULATION BE PREDICTED?
Demographers use
numerous tools and
graphs to predict
populations:
Age structure graphs
Survivorship curves
Fertility rates
Migration patterns
8. AGE STRUCTURE GRAPHS
Graph that shows the
distribution of ages in a specific
population at a certain time.
A.K.A. population pyramids
Parts of an age structure graph:
Bars = ages
Colors = gender
Numbers on bottom= percentage
of the population
3 Categories of Age Structure
Graphs
Rapid growth
Slow growth
Declining/zero growth
9. AGE STRUCTURE GRAPHS
Rapid growth
Young people
dominate population
Has population
momentum- more
children will move up
to become
reproductive
Rapid increase in birth
rates once the
youngsters reach
reproductive age.
EX: Developing
countries- many
countries in Africa,
Mexico, S. America
10. AGE STRUCTURE GRAPHS
Slow Growth
Birth rates = death
rates
All age groups are
about equal
EX: Most Western
European countries,
U.S.
11. AGE STRUCTURE GRAPHS
Declining Growth
(Zero growth)
Birth rates are lower
than death rates
Many more older
people who are not
reproducing
Fewer younger people
Population will become
much smaller when
they die.
Ex: Germany, Russia
12. SURVIVORSHIP CURVES
Percentage of members of a
group that are likely to
survive to any given age.
Follows a group of
organisms from the time they
were born to the time they
die to see trends.
3 Types of Survivorship
curves:
Type I
Type II
Type III
13. SURVIVORSHIP CURVES
Type I
Lots of offspring survive and live
to old age.
Ex: Developed countries- US,
Japan
Ex: Zebras, Bears, etc.
Type II
Populations have a similar death
rate at all ages
Ex: birds
Type III
Lots of offspring die young & very
few survive to old age.
Ex: Developing countries- Africa,
Asia
Ex: insects, clams
14. FERTILITY RATES
Fertility rate- number of babies
born each year per 1,000
women in a population.
Total fertility rate- avg.
number of children a woman
gives birth to in her lifetime.
Replacement level fertilityavg number of children each
parent must have in order to
“replace” themselves in the
population.
RLF = approximately 2 children
Compare Zambia to Europe

15. FERTILITY RATES
Keeping total fertility rate
below replacement level
fertility will help populations
decline.
This graph shows US
population change since 1920.
Who are the baby boomers?
Lots of babies were born post
WWII…when soldiers returned
home from war ;)
Why did population start rising
in the 1990’s? Children of baby
boomers were growing up &
having kids
16. MIGRATION PATTERNS
Immigrationmovement into an area
Emigrationmovement out of an
area
US experiences lots of
immigration… would
our population decline
if we didn’t have
immigration?
17. WHAT FACTORS AFFECT A COUNTRY’S DEATH
RATE?
Life expectancy- avg. number
of years members of a
population are likely to live.
Most affected by infant
mortality- death rate of infants
less than a year old.
Infant mortality (death rates)
have decreased and life
expectancy has increased due
to access to
adequate food
clean water
safe sewage disposal
vaccines (around beginning of
20th century)
access to education
Worldwide Infant mortality rates
18. WHAT FACTORS AFFECT A COUNTRY’S DEATH
RATE?
Threats to life
expectancy :
As populations
increase, population
becomes denser
Disease can spread
quickly thru dense
populations.
Ex: AIDS, tuberculosis
This will increase death
rate and decrease life
expectancy.
Sign located in South African
village.
19. WHAT FACTORS AFFECT A COUNTRY’S BIRTH
RATE?
Birth rates typically are
lower in areas where:
Women are educated
Academically
Family planning techniques
Women are economically
independent
Have jobs
So less time for raising many
children.
Pensions are available for
elderly
no need for kids to help take
care of elderly
20. WHAT FACTORS AFFECT A COUNTRY’S BIRTH
RATE?
Large families are
common when children
are needed to work
and take care of older
family members
As countries
modernize, there is
less need for lots of
kids.
This can decrease birth
rates.
21. WHAT FACTORS AFFECT A COUNTRY’S BIRTH
RATE?
Factors that can increase
a population’s birth rate:
Lack of birth control due
to availability or religion
Need to have children b/c
have poor health care
and children can die
easily
Women are uneducated,
repressed, with no rights
to make decisions about
their own bodies.
22. WHAT IS THE DEMOGRAPHIC TRANSITION?
Pattern
of falling death
rates & birth rates due to
improved living
conditions.
All countries should
experience this trend in
population change.
23. WHAT ARE THE STAGES OF DEMOGRAPHIC
TRANSITION?
Preindustrial societiesHigher birth rates- due to
need for kids to help on
farm; have lots of kids
because many will die
from disease/malnutrition.
Higher death rates- due
to food shortages,
malnutrition, lack of
sanitation & medicine,
accidents, other hazards
Population is low
because of high death &
birth rates.
24. WHAT ARE THE STAGES OF DEMOGRAPHIC
TRANSITION?
Industrialization
Decreasing death ratesdue to improved health
care and sanitation.
Continuing high birth
rates- people still having
lots of kids because
healthcare is not
widespread and may be
ignorant about birth
control
People have better jobs,
more income, more
people surviving due to
rise in standard of living.
Population grows
exponentially.
25. WHAT ARE THE STAGES OF DEMOGRAPHIC
TRANSITION?
Mature Industrial
Death rates continue
declining
Birth rates begin
declining
Women realize they
don’t need as many kids
Women realize how
expensive kids are
Women may have jobs
so less time for kids
26. WHAT ARE THE STAGES OF DEMOGRAPHIC
TRANSITION?
Postindustrial
societieseventually BR & DR
level out &
population is at
equilibrium. W.
Europe saw this in
19th & 20th century
Editor's Notes
I AmNujood, Age 10 and Divorced is the autobiography of a 10 year old 3rd grader from Yemen who is married off to a man 3x her age to help her family. Her father cannot support his family so he basically trades his 10 year old for money/goods. The husband rapes his new wife even though he promised not to consummate the marriage until 1 year after her first menstrual cycle. Shows how women in 3rd world countries are dependent on men, uneducated, and have no rights.
