![]() ![]() The decrease in birth rates around the world is linked to a number of factors. Thus, as in the U.S., the global population should increase more slowly in the future. However, it is expected that from 2050 to 2055, the global birth rate-14.4-will be nearer the projected global death rate of 9.9. The birth rate worldwide from 1950 to 1955-37.0 per 1,000 people-was almost twice as high as the death rate of 19.1 per 1,000 people. Consequently, population growth from 2010 to 2050 should be much slower than it was from 1950 to 2010.Ī similar convergence in birth rates and death rates is underway globally. By mid-century, from 2050 to 2055, the birth rate is projected to drop further to 12.2 and the death rate to rise to 10.2. had fallen to 13.2, much closer to the crude death rate of 8.3. By 2010-2015, the crude birth rate in the U.S. 34 Thus, population growth was more robust in the past. ![]() That was more than double the crude death rate of 9.6 per 1,000 people. Both trends-falling birth rates and rising life expectancy-have been more pronounced globally than in the U.S.įrom 1950 to 1955, the crude birth rate in the U.S. At the same time, life expectancy has improved significantly and has contributed to the aging of populations. and in the world, birth rates have trended down since 1950, and the gap with respect to death rates has narrowed sharply, leading to a slowdown in population growth. The growth of a population and changes in its age structure are closely related to trends in birth and death rates and changes in life expectancy. Birth Rates, Death Rates, and Life Expectancy The average annual rate of growth-0.8%-is only slightly higher than the rate projected for the U.S. In the future, the global population is expected to increase from 6.9 billion in 2010 to 9.6 billion in 2050, or by 38%. The average annual rate of growth-1.7%-was much higher than in the U.S. From 1950 to 2010, the world population increased from 2.5 billion to 6.9 billion, or by 174%. The projected slowdown in population growth is even sharper in the world overall. population is only about half the rate of growth experienced in the recent past. Thus, the projected annual rate of growth in the U.S. population had increased from 157.8 million to 312.2 million, a total gain of 98% at an average annual rate of 1.1%. In the six decades from 1950 to 2010, the U.S. population is significantly slower than in the past. The anticipated annual rate of growth in the U.S. 33 For this four-decade period, that is an increase of 28% at an average annual rate of 0.6%. population is projected to increase from 312.2 million in 2010 to 400.9 million in 2050. Thus, the social and economic effects of aging are likely to be felt more acutely in the future. But future prospects for aging have garnered more attention because, unlike in the past, younger populations, those of children and those of middle-age adults, are at near standstill. and global populations also turned older from 1950 to 2010. However, population growth from 2010 to 2050 is projected to be significantly slower and is expected to tilt strongly to the oldest age groups, both globally and in the U.S.Īging is not exactly news-the U.S. Growth from 1950 to 2010 was rapid-the global population nearly tripled, and the U.S. and the world looks very different than the recent past in key respects.
