Which countries will grow the most by 2050? Where do people live the longest? How does contraceptive prevalence vary worldwide?

Find the answers in PRB’s interactive map. Browse through 17 indicators organized in six tabs, ranging from life expectancy, HIV/AIDS, family planning, health, and more. View data on global, regional, or country maps or tables. You can easily embed the map on your blog or website.


Due to their size, the following countries and territories are not represented on the map: Faro Island, Denmark; Gibraltar; Hong Kong SAR; Liechtenstein; Maldives; Monaco; San Marino; Seychelles; St. Helena Island; and Vatican City.


The Data Sheet lists all geopolitical entities with populations of 150,000 or more and all members of the UN. These include sovereign states, dependencies, overseas departments, and some territories whose status or boundaries may be undetermined or in dispute. More developed regions, following the UN classification, comprise all of Europe and North America, plus Australia, Japan, and New Zealand. All other regions and countries are classified as less developed. The least developed countries consist of 48 countries with especially low incomes, high economic vulnerability, and poor human development indicators; 33 of these countries are in sub-Saharan Africa, 14 in Asia, and one in the Caribbean. The criteria and list of countries, as defined by the United Nations, can be found at www.unohrlls.org/en/ldc/.

Sub-Saharan Africa: All countries of Africa except the northern African countries of Algeria, Egypt, Libya, Morocco, Tunisia, and Western Sahara.

World and Regional Totals: Regional population totals are independently rounded and include small countries or areas not shown. Regional and world rates and percentages are weighted averages of countries for which data are available; regional averages are shown when data or estimates are available for at least three-quarters of the region’s population.

World Population Data Sheets from different years should not be used as a time series. Fluctuations in values from year to year often reflect revisions based on new data or estimates rather than actual changes in levels. Additional information on likely trends and consistent time series can be obtained from PRB, and are also available from UN and U.S. Census Bureau publications and websites.


The rates and figures are primarily compiled from the following sources: official country statistical yearbooks, bulletins, and websites; the United Nations Demographic Yearbook, 2009-2010 and Population and Vital Statistics Report of the UN Statistics Division; World Population Prospects: The 2010 Revision of the UN Population Division; and the International Data Base of the International Programs Center, U.S. Census Bureau. Other sources include recent demographic surveys such as the Demographic and Health Surveys, Reproductive Health Surveys, special studies, and direct communication with demographers and statistical bureaus in the United States and abroad. Specific data sources may be obtained by contacting the authors of the 2012 World Population Data Sheet. For countries with complete registration of births and deaths, rates are those most recently reported. For more developed countries, nearly all vital rates refer to 2011 or 2010.
