Study Notes

Constants

A constant is an unchanging number that can be used to multiply rates, ratios, or proportions to make them more understandable.
For example, a birth rate of 0.0184 per person in Hungary in 2008, can be multiplied by 1000 to get 18.4 births per 1000 people.

Cohort Measures

A cohort is a group of people sharing a common demographic experience who are observed through time.
Birth cohorts are the most common, but marriage cohorts and school class cohorts are also used.
Most annual rates (e.g., birth rate) relate demographic events to the population at mid-year (July 1).

General Fertility Rate

General fertility rate is the number of live births per 1,000 women ages 15 to 49 in a given year.
It's a more refined measure than the birth rate because it considers the age-sex group at risk of giving birth.
In 2010, Egypt's general fertility rate was 91 births per 1,000 women ages 15 to 49.
Zambia's rate was 214, one of the highest, and Taiwan's rate was 36, one of the lowest.

Age-Specific Fertility Rate

Fertility rates can be calculated for specific age groups to understand differences in fertility behavior.
In 2008, there were 103 live births per 1,000 women ages 20 to 24 in the U.S.
Tanzania's rate was 260 from 2007 to 2010, Guyana's was 163 from 2006 to 2009, and Japan's was 38 in 2008.

Total Fertility Rate (TFR)

TFR is estimated by summing up age-specific fertility rates multiplied by 5, simulating the likelihood of a woman giving birth during each five-year period of her childbearing years.
In 2008, the TFR in the U.S. was 2.09, meaning the average woman would have 2.09 children by age 49.
A TFR of 2.1 is considered replacement-level fertility in developed countries.

Population Momentum

Population momentum is the tendency of a population to continue growing even after replacement-level fertility is reached.
This occurs because past high fertility leads to a large concentration of people in younger age groups.
It takes several generations for births to balance deaths and stabilize population growth.

Birth Rate for Unmarried Women

The birth rate for unmarried women is the number of live births by unmarried women per 1,000 unmarried women ages 15 to 49 years in a given year.
