According to U.S. Census Bureau, there were 40.3M U.S. residents 65 years and older in the 2010 Census and 54.1M in the July 1, 2019, population estimates.
Today, there are more than 46 million older adults age 65 and older living in the U.S.; by 2050, that number is expected to grow to almost 90 million. Between 2020 and 2030 alone, the time the last of the baby boom cohorts reach age 65, the number of older adults is projected to increase by almost 18 million.
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.
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.
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.
Because of increases in life expectancy at older ages, people 90 and older now comprise 4.7 percent of the older population (age 65 and older), as compared with only 2.8 percent in 1980. By 2050, this share is likely to reach 10 percent.
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.
Social Security provides the largest share of aggregate income for units aged 65 or older. Aggregate income for the aged population comes largely from four sources. Social Security accounts for 33.2%, earnings for 32.2%, pensions for 20.9%, and asset income for 9.7%.
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 four major old age problems include:
the United States 2020 population is estimated at 331,002,651 people at mid year according to UN data. the United States population is equivalent to 4.25% of the total world population. the U.S.A. ranks number 3 in the list of countries (and dependencies) by population.
