The U.S. Census Bureau published a new report on global population aging. The report provides full details on the various trends related to global aging, including the speed of aging and the size of the more elderly population (65 or more) in different regions of the world.
According to the report, the world population is aging rapidly. The percentage of the population aged 65 or older is expected to double between 2015 and 2050, from 8.5% (617 million) in 2015 to 16.7% (1,600 million) by 2050.

Europe is the most aged region today, with about 17 percent of its population of 65 or more, and is expected to remain so in the year 2050, when it is estimated that 27.8% of its population will fall within this age group. According to the report, this global aging trend is mainly due to the increase in life expectancy and lower fertility rates, which are close to or below the replacement level of 2.1 in all regions, except Africa.
