Age-Specific Fertility Rate (ASFR): the
number of births to women of a given age group per
1,000 women in that age group. It is calculated by dividing the number of births born
to women of a particular age group by the female population in that age group
multiplied by 1,000.

multiplied by 1,000.
Crude Birth Rate : the
number of births per 1,000 population in a given year.
Fertility: the
actual reproductive performance of an individual, a couple, a group, or a
population.

Fertility Rate (General Fertility
Rate): the number of births per 1,000 women aged 15-49
years in a given year.
years in a given year.
Total Fertility Rate: is a fertility index combining age-specific
fertility rates. It represents the
average number of children that would be born to a woman throughout her lifetime
given that the age-specific fertility rates still prevail at that time. It is computed using
the formula TFR =5å ASFR if 5-year age groups are employed or TFR - å ASFR if
single age group is employed.

Growth Rate : the
rate at which a population is increasing (or decreasing) in a given year due
to natural increase and net migration, expressed as a percentage of the base
population.

Household : a social
unit consisting of a person living alone or a group of persons who sleep
in the same housing unit and have a common arrangement in the preparation and
consumption of food.

Life Expectancy: represents
the average remaining number of years for a person who
survives at the beginning of a given age interval. Most commonly cited as life
expectancy at birth.

Migration: the
movement from one place to another (especially from one country to another)
usually with intention to settle.

Net Migration Rate : is the
difference between in-migration and out-migration rates. It
represents the difference between the people coming into an area and those going out
of the area.

number of individuals in a territory or a locality living at a specified moment
of time with an agreed definition of residence; all the persons falling within the scope of
a census or other inquiry.
