2023 World Population Data
For more than 60 years, PRB’s World Population Data Sheet has been one of the most trusted sources for vital demographic data used by government leaders, policymakers, researchers, academics, and decisionmakers around the world. It offers the latest population, health, and environment indicators for more than 200 countries and territories, each carefully researched and vetted by PRB’s expert team of demographers and analysts. This year’s special focus is on climate vulnerability and resilience.
Featured World Indicators
Projected Deaths per 100,000 Due to Temperature Change (2040-2059 Annual Average)
The mean projected change in annual death rates per 100,000 people in a country that resulted from the impact of climate change on daily temperature, in contrast to a future scenario where climate change is absent. Data correspond to the projections for the years 2040-2059 and are from the Climate Impact Lab and UNDP.
Internally Displaced Persons Due to Disasters
The number of people as of the end of 2022 forced to evacuate or flee their homes or places of usual residence due to natural or human-made disasters and who, in doing so, have not crossed internationally recognized borders. Data are from IDMC.
Urban Population Living in Slum Households (%)
The percentage of the urban population living in slum households. A slum household is defined as a group of individuals living under the same roof lacking one or more of the following conditions: access to improved water, access to improved sanitation, sufficient living area, housing durability, and security of tenure. While the term slum has a derogatory connotation, it continues to be used in data collection categories such as this one. Data are for the most recent year available since 2018 and are from UN-HABITAT.
Moderate/Severe Food Insecurity (%)
The percentage of the total population estimated to be experiencing difficulties in obtaining sufficient, safe, and nutritious food for healthy living. Moderate food insecurity implies compromised food quality and quantity, accompanied by concerns about food access due to financial constraints. Severe food insecurity extends to individuals who have entirely depleted their food supply, even going without meals for days. Data presented are the three-year average between 2020 and 2022 and are from the FAO.
