This database is the core of the latest Revision of World Population Prospects, the United Nations estimations and projections of population for all countries of the world, covering the period 1950-2100. It incorporates the findings of the most recent national population censuses and of numerous specialized population surveys carried out around the world. The latest Revision provides the demographic data and indicators to assess trends at the global, regional and national levels and to calculate many other key indicators commonly used by the United Nations system.
The Urban/Rural Population database provides data on urbanization, a movement of people from rural to urban areas with population growth.
The interactive database International Migrant Stock provides the number of people born in a country other than that in which they live. It also includes refugees. The basic data to estimate the international migrant stock were obtained mostly from population censuses held during the decennial rounds of censuses. Some of the data used were obtained from population registers and nationally representative surveys.
The World Population Policies database provides information on Government views and policies on population size and growth, population age structure, fertility, reproductive health and family planning, health and mortality, spatial distribution and internal migration, and international migration. It also provides information on selected demographic and socio-economic indicators
