(2009) The U.S. population is projected to increase over the next four decades, but according to new supplemental projections from the U.S. Census Bureau, the rate of increase depends largely on future trends in international migration.

The world population is growing older. With continued declines in fertility and mortality, the global population's shift toward an older age structure, known as population aging, will accelerate. Older adults' (ages 65+) share of the global population increased from 5 percent in 1960 to 9 percent in 2018 and is projected to rise to 16 percent by 2050, with the segment ages 85 and older growing the fastest. Children's (ages 0 to 14) share is falling, from 37 percent in 1960, to 26 percent in 2018, with a projected decrease to 21 percent by 2050.
Population Bulletin, Vol. 66, No. 1: In 2011, the oldest baby boomers—Americans born between 1946 and 1964—will start to turn 65.
(2002) The U.S. population is growing as fast as or faster than any other more developed country. Between 1990 and 2000, nearly 33 million people were added to the U.S. population—a group nearly as large as Argentina's population, and the greatest 10-year increase ever for the country.

The Center for Public Information on Population Research at PRB helps improve the translation and dissemination of major findings from population dynamics research and the communication and cooperation across the NICHD Population Dynamics Research Centers.
(2011) The world's population is growing—and aging. Very low birth rates in developed countries, coupled with birth rate declines in most developing countries, are projected to increase the population ages 65 and over to the point in 2050 when it will be 2.5 times that of the population ages 0-4. This is an exact reversal of the situation in 1950.
