Population
Total Population - Both Sexes	Total Population - Both Sexes
Total Population - Female	Total Population - Female
Total Population - Male	Total Population - Male
Population Growth Rate	Average exponential rate of growth of the population over a given period. It is calculated as ln(Pt/P0)/t where t is the length of the period. It is expressed as a percentage.
Rate of Natural Population Increase	Crude birth rate minus the crude death rate. Represents the portion of population growth (or decline) determined exclusively by births and deaths.
Sex Ratio of Total Population	Number of males per 100 females in the population.
Median Age of Population	Age that divides the population in two parts of equal size, that is, there are as many persons with ages above the median as there are with ages below the median.
Population Density	Population per square Kilometre.
Population by Age Groups - Both Sexes	Quinquennial Population by Five-Year Age Groups - Both Sexes
