| Résumé : | World Population Prospects 2022 is the twenty-seventh edition of the official United Nations population estimates and projections. It presents population estimates from 1950 to the present for 237 countries or areas, underpinned by analyses of historical demographic trends. This latest assessment considers the results of 1,758 national population censuses conducted between 1950 and 2022, as well as information from vital registration systems and from 2,890 nationally representative sample surveys. The 2022 revision also presents population projections to the year 2100 that reflect a range of plausible outcomes at the global, regional and national levels. For the first time, the estimates and projections are presented in one-year intervals of age and time instead of the five-year intervals used previously. The world’s population continues to grow, but the pace of growth is slowing down. Rates of population growth vary significantly across countries and regions. Levels and patterns of fertility and mortality vary widely around the world. The population of older persons is increasing both in numbers and as a share of the total. A sustained drop in fertility leads to an increased concentration of the population at working ages, creating an opportunity for accelerated economic growth per capita. More and more countries have begun to experience population decline. International migration is having important impacts on population trends for some countries. The COVID-19 pandemic has affected all components of population change, including fertility, mortality and migration. Population data provide critical information for use in development planning |
