Population growth (annual %)

Annual rural population growth rate for year t is the exponential rate of growth of midyear rural population from year t-1 to t, expressed as a percentage. Rural population refers to people living in rural areas as defined by national statistical offices. It is calculated as the difference between total population and urban population.

Urban population refers to people living in urban areas as defined by national statistical offices. The data are collected and smoothed by United Nations Population Division.

Urban population refers to people living in urban areas as defined by national statistical offices. It is calculated using World Bank population estimates and urban ratios from the United Nations World Urbanization Prospects. Aggregation of urban and rural population may not add up to total population because of different country coverages.

Population density is midyear population divided by land area in square kilometers. Population is based on the de facto definition of population, which counts all residents regardless of legal status or citizenship--except for refugees not permanently settled in the country of asylum, who are generally considered part of the population of their country of origin. Land area is a country's total area, excluding area under inland water bodies, national claims to continental shelf, and exclusive economic zones. In most cases the definition of inland water bodies includes major rivers and lakes.

Male population is based on the de facto definition of population, which counts all male residents regardless of legal status or citizenship.

Female population is based on the de facto definition of population, which counts all female residents regardless of legal status or citizenship.
