|Age specific fertility rate
||Number of live births to a given age group
||num. of live births / num. of woman in that age group
|Age specific death rate
||Number of deaths for a given age group
||A population dominated by old age, retired people who are no longer or less economically active 65+. Caused by a high life expectancy & falling birth rate.
||Number of live births per 1000 people
||live births / total population * 1 000
||The number of people that can be supported by the available resources of a given area/ecosystem.
||Number of children who die under 5 years of age. It encompasses both infant and neonatal mortlaity. NB: the age range may differ, some consider the child range below 14 yrs
|Death Rate/ Crude Death Rate
||Number of deaths per 1000 people
||deaths / total population * 1 000
||Number of uneconomically active people between 0 - 14 & 65 + who are dependent on 15 - 64 working age group.
|| (0 - 14 + 65+)/ 15- 64
||A model showing birth & death rate changes and the resultant population changes at different stages of a population.
||One who leaves his/her place of living (country, city, town or village) to permanently or temporarily settle in a new area.
||The ability to reproduce offsprings.
||The reproductivity of an individual or the whole population
||Number of live birth ages 15 - 49 per 1 000 woman
||num. of births /woman 15 - 49 * 1 000
||One who settles in another area from somewhere.
||Number of children per 1 000 live births who die below one year. They encompass neonatal mortality and are in the under 5 mortality group.
||Num. of deaths below 1 yr / Num. of live births *1 000
||The number of years a person is expected to live if current mortality trends where to prevail throughout his/her lifetime.
||The number of woman who die during pregnancy (pregnancy related deaths) or after 42 days (but less than a year) of delivery per 100 000 live births.
||num. of maternal deaths / total num. of live births * 100 000
||The differences between births and deaths in a population. Natural change can be an increase or decrease. Natural increase is when births are higher than deaths whereas natural decrease deaths are higher than births(negative). Natural change is a contributor to population growth along with migration.
||num. of births - num. of deaths
||Number of children per 1 000 live births who die, usually before a month but before a year. They are in the under 5 and infant mortality genre.
||num. of infant deaths > 28 and > 1 year/live births * 1 000
||Net effect of immigrants or emigrants in an area.
||immigrants - emigrants
|Population Change/ Population Growth
||An increase or decrease in population due to natural change and migration.
||Natural change (births - deaths) + Net migration
||The least number of children need to be reproduced by a woman in order to replace them in the population over the next generation. Recommended replacement level is 2.1 per woman but can vary with countries and mortality trends
||A lifeless (dead) baby after 28 weeks of pregnancy.
|Total Fertility Rate
||The number of children that would be born to a woman during her lifetime if she conformed to the age specific fertility rates of given year.
