Population Growth Rate Charts in Sierra Leone

Terminology

Total population is based on the de facto definition of population, which counts all residents regardless of legal status or citizenship. The values shown are midyear estimates.
Annual population growth rate for year t is the exponential rate of growth of midyear population from year t-1 to t, expressed as a percentage .
Fertility rate, total (births per woman): the number of children that would be born to a woman if she were to live to the end of her childbearing years and bear children in accordance with age-specific fertility rates of the specified year.
Net migration is the number of immigrants minus the number of emigrants, including citizens and noncitizens, for 1 year period. It is the net total of migrants during the period, that is, the total number of immigrants less the annual number of emigrants, including both citizens and noncitizens.
Life expectancy at birth indicates the number of years a newborn infant would live if prevailing patterns of mortality at the time of its birth were to stay the same throughout its life. It reflects the overall mortality level of a population, and summarizes the mortality pattern that prevails across all age groups in a given year.
Crude death rate indicates the number of deaths per 1,000 midyear population. It indicates the number of deaths occurring during the year, per 1,000 population estimated at midyear. Subtracting the crude death rate from the crude birth rate provides the rate of natural increase, which is equal to the rate of population change in the absence of migration.
Crude birth rate indicates the number of live births per 1,000 midyear population. It indicates the number of live births occurring during the year, per 1,000 population estimated at midyear. Subtracting the crude death rate from the crude birth rate provides the rate of natural increase, which is equal to the rate of population change in the absence of migration.
