The world population will reach 9.8 billion in 2050, up 31 percent from an estimated 7.5 billion now, according to projections included in the 2017 World Population Data Sheet from the Population Reference Bureau (PRB).
This edition of the annual Data Sheet, available at www.worldpopdata.org, also shows a worldwide total fertility rate (TFR, or average lifetime births per woman) of 2.5. The three countries with the highest TFRs are Niger (7.3), Chad (6.4), and Somalia (6.4), while there is a five-way tie for the lowest TFR (1.2) among Bosnia-Herzegovina, Romania, Singapore, South Korea, and Taiwan.
PRB’s widely referenced Data Sheet has been produced annually since 1962. This year’s edition provides the latest data on 17 key population, health, and environment indicators for the world, major regions, and more than 200 countries. Source: Population Reference Bureau
Special Focus on Youth
This year’s Data Sheet also includes nine special indicators and six analytical graphics assessing whether youth (generally defined as people ages 15 to 24) are well-positioned to develop into productive adults, based on health, education, and other factors. The Data Sheet includes indicators for secondary and tertiary school enrollment, adolescent fertility rates, rates of HIV/AIDS among youth, youth population figures for 2017, and youth population projections for 2050. A few key figures are:
The world youth population (ages 15 to 24) is projected to rise to 1.4 billion in 2050 from 1.2 billion now but the youth share of world population will fall to 14 percent from 16 percent.
strong>Africa’s youth population will rise to 35 percent of the world youth total in 2050, from 20 percent today.
Ethiopia currently has the highest share of youth population at 21.8 percentwhile Bulgaria has the lowest share at 9.1 percent.
The global adolescent fertility rate (ages 15 to 19) is 50 births per 1,000 women, compared to only 16 per 1,000 in more-developed countries and 54 per 1,000 in less-developed countries.
