# Demography

Demography is the statistical study of human population. It encompasses the study of the size, structure, and distribution of these populations.

#### Crude Birth Rate (CBR)

CBR measures the number of live births per 1000 population in a given year.

#### Age-Specific Fertility Rate (ASFR)

ASFR measures the annual number of births to women of a specified age or age group per 1,000 women in that age group.

#### General Fertility Rate (GFR)

GFR is the number of live births per 1000 women ages 15-49 in a given year.

#### Total Fertility Rate (TFR)

TFR is the sum of the Age-Specific Fertility Rates (5-year age groups between 15 and 49) for female residents during a year multiplied by 5, whole divided by 1000.

#### Crude Death Rate (CDR)

CDR is the total number of deaths to residents in a given year divided by the total population of that year per thousand.

#### Infant Mortality Rate (IMR)

IMR is the number of new born dying under one year of age divided by the number of live births per thousand.

#### Neonatal mortality rate (NMR)

NMR the ratio of the number of deaths of children less than 29 days of age in one year to the number of live births in that year per thousand.

#### Post neonatal mortality rate (PNMR)

PNMR the ratio of the number of deaths in one year of children more than 29 days up to one year of age to the number of live births in that year per thousand.

#### Demographic Dividend

An increase in the working age ratio can raise the rate of economic growth. This known as ï¿½demographic dividend.ï¿½
