In 2019, about 16.5 percent of the American population was 65 years old or over; a figure which is expected to reach 22 percent by 2050.
Share of old age population (65 years and older) in the total U.S. population from 1950 to 2050.

In 2020, there are an estimated 727 million persons aged 65 years or over worldwide. This number is projected to more than double by 2050, reaching over 1.5 billion persons. The share of older persons in the global population is expected to increase from 9.3 per cent in 2020 to 16.0 per cent in 2050.
In the United States, the population age 65 and older numbered 52.4 million in 2018 (the most recent year for which data are available). They represented 16% of the population, more than one in every seven Americans.
The Older American Population In the U.S. the population age 65 and older numbered 54.1 million in 2019 (the most recent year for which data are available). They represented 16% of the population, more than one in every seven Americans.
Between 2006 and 2016 the population age 60 and over increased 36% from 50.7 million to 68.7 million. 2040 (a 129% increase). population) to 11.1 million in 2016 ( 23% of older adults) and are projected to increase to 21.1 million in 2030 (28% of older adults).
Population of the United States by sex and age 2020 The estimated population of the U.S. was approximately 329.48 million in 2021, and the largest age group was adults aged 25 to 29. There were 11.88 million males in this age category and around 11.36 million females.
The United Nations has agreed that 65+ years may be usually denoted as old age and this is the first attempt at an international definition of old age. However, for its study of old age in Africa, the World Health Organization (WHO) set 55 as the beginning of old age.
The world’s total population aged 90+ years was estimated at 21,328.78 thousand persons in 2020.
69 percent In 1990, women made up a greater share of older adults living alone (79 percent). But since then, the percentage of older women living alone has decreased from 38 percent to 32 percent, while the percentage of older men living alone has risen slightly from 15 percent to 18 percent.
In 2019, about 16.5 percent of the American population was 65 years old or over; a figure which is expected to reach 22 percent by 2050. This is a significant increase from 1950, when only eight percent of the population was 65 or over.
A General overview At global level, the share of 80+ people rose from 0.6% in 1950 (15 million) to around 1.6% (110 million) in 2011, and it is expected to reach 4% (400 million) by 2050.
Changes in Metabolism At the same time, total body fat typically increases with age. This often can be explained by lower metabolic rate in addition to too many calories. As people age, fat tends to concentrate in the trunk and as fat deposits around the vital organs.
This will result in a shift in the age structure, from 13 percent of the population aged 65 and older in 2010 to 19 percent in 2030. In 2010, 60 percent of the U.S. population will be aged 20–64. By 2030, as the baby boomers age, the proportion in these working ages will drop to 55 percent.
