Study Notes

Demography

Demography is the study of population.
Demographers study population size, trends, and the implications for societies.
They use data from censuses, birth and death records, and surveys.

Key Demographic Terms

Count - The absolute number of a population or demographic event in a specified area and period.
Rate - Frequency of an event in a population divided by the population at risk.
Ratio - Relation of one population subgroup to the total population or to another subgroup, expressed as a ratio.
Proportion - Relation of a population subgroup to the entire population, expressed as a proportion.

Examples of Demographic Measures

Example: There were 18.4 abortions per 1,000 women in Hungary in 2008.
Example: In 2010, there were 94 males per 100 females in France.
Example: The age-dependency ratio in Uganda in 2009 was 106.
Example: In India in 2006, 27 percent of women ages 15 to 19 were married, while 93 percent of women ages 30 to 34 were married.
Example: Virtually all Nigerian women surveyed in 2008 who had an infant under age 1 were breastfeeding.
Example: In Bolivia in 2008, the contraceptive prevalence rate for all methods among currently married women ages 15 to 49 was 61 percent, whereas the modern method contraceptive prevalence rate for married women was 35 percent.

Population Pyramid

A population pyramid graphically displays a population's age and sex composition.
Each age group's numbers or proportions are displayed using horizontal bars.
Population pyramids show the effects of events such as wars and economic changes on population structure.

Comparing Populations

Populations with a high proportion of elderly people are likely to have more deaths and fewer births than populations with a high proportion of young families.
When comparing populations, it is essential to consider the age structure of the population.

Contraceptive Prevalence Rate (CPR)

The CPR is the number of women of reproductive age using contraception per 100 women of reproductive age.
The CPR indicates the number of women at lower risk of conception at a given time.
CPR measures can be calculated for all women or subpopulations.
