PRB PROJECTS 2050 WORLD POPULATION AT 9.8 BILLION,
YOUTH POPULATION TO REACH 1.4 BILLION
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.
