HSS 3108 Midterm 2 Exam Questions and Answers| New Update with 100% Correct Answers
Demography - Demography is the scientific study of various aspects of human populations
including the structure, distribution, density and trends
- Understanding the age structure, birth rates, death rates, and migration patterns of a
population is crucial for predicting and planning or future health needs.
- Demographic changes often coincide with epidemiological transitions, shifting disease
burdens from infectious to chronic diseases as populations age and develop economically
- The increasing proportion of older adults in many countries has significant implications for
healthcare systems, including rising demand for long-term care and management of chronic
conditions
Common demographic indicators - Total Fertility Rate (TFR): Indicates the average number
of children a woman is expected to have during her lifetime, providing insight into population
growth trends.
- Life expectancy at birth: measures the average number of years a newborn is expected to live,
reflecting overall health and mortality conditions in a population.
- Infant mortality rate (IMR): the number of infant deaths (under one year) per 1000 live births,
a critical indicator of maternal and child health
- Population growth rate: The annual percentage change in a population size, providing insights
into trends in birth, death, and migration rates.
- Dependency ratio: The ratio dependents (young and elderly) to the working-age population,
indicating the economy burden on the productive segment of society
Common demographic indicators (pt.2) - Crude birth rate (CBR): the number of live births
per 1000 people in a population per year, useful for assessing population and growth rates
,- Crude death rate (CDR): the number of deaths per 1000 people in a population per year,
important for understanding the overall health and mortality trends
- Net migration rate: the difference between the number of immigrants and emigrants per 1000
people in a population, indicating population movements and changes in demographics
- Sex ratio: the ratio of males to females in a given population, often expressed as males per
100 females, important for understanding gender dynamics within a population
- Urbanization rate: the percentage of the population living in urban areas, illustrating trends in
migration and development, affecting socio-economic conditions.
Demographic dividendss The demographic dividend refers to the potential economic growth
that can occur when a country's population structure shifts, resulting in a larger proportion of
working-age individuals relative to dependents.
- As countries develop, they typically experience a decline in both birth rates and death rates.
This leads to a temporary period where the working-age population (15-64) grows faster than
the dependent population (children and elderly)
- This shift in age structure can create favourable conditions for economic growth, as there are
more potential workers and fewer dependents to support.
- The demographic dividend is not permanent. As the population continues to age, the
proportion of elderly dependents increases, potentially closing the window of opportunity
- Different nations experience the demographic dividend at different times and to varying
degrees, depending on their specific demographic transitions and policy environments.
Policy approaches The dividend isn't automatic. It's a potential for growth that only smart
policies can materialize. Therefore, countries must invest efficiently during this period to reap
long-term benefits. For instance:
- Investing in human capital through education and skills training
- Creating job opportunities for the growing workforce
- Promoting gender equality and women's participation in the labor force
,- Encouraging savings and investment.
Demographic transition - Demographic changes exert powerful forces on health and well-
being within and between urban areas, and create new needs and challenges for health
programming in all cities and regions
- Drivers of DT include improvements in healthcare, sanitation, nutrition, education and
economic development
- Countries progress through the stages at different rates. Some may skip stages or experience
them differently
- Most developed countries are currently in Stage 4. Many developing countries are in Stage 2
or 3
Demographic transition model ...
Demographic transition: stage 1 - High stationary (population stays about the same)
- Lots of babies are born, but lots of people die too
- Eg. Medieval Europe: high birth rates because no birth control
High death rates because:
- Widespread poverty, lack of access to clean water and sanitation
- Inadequate health services
Demographic transition: stage 2 - Early expanding (population starts growing fast)
- Still lots of babies, but fewer people dying
- Eg. England in the 1800's
* Birth rates still high
* Death drop because:
- Better food supply,
- Improved sanitation
, - Basic healthcare
Demographic transition: stage 3 - Late expanding. Population still growing but slower
- Still lots of babies but fewer people dying
- Eg. Modern day India
* Birth rates falling constantly because of:
- Increased literacy rate
- Women empowerment
- Access to birth control
* Death rate keeps falling
Demographic transition: Stage 4 - Low stationary: population growth is stable
- Few babies born, few people dying
- Eg. Modern day USA
* Birth rates falling drastically because of:
- High cost of raising children
- Focus on careers
- Widely available family planning methods
* Low death rates due to good health care
Demographic transition: stage 5 - Very few babies are born, slightly more people dying
- Population shrinking
- Eg. Modern day Japan
* Birth rates very low because of:
- High cost of living
- High educational levels
- Cultural shifts
