According to the forecast, there will be 4.2 million over-65s in the Netherlands by the year 2030, 920 thousand more than the current number (start of 2019, provisional figure). This group will constitute 23 percent of the population by that year, versus 19 percent at present.
The number of older persons is expected to double again by 2050, when it is projected to reach nearly 2.1 billion. The older population of the developing regions is growing much faster than in the developed regions.
Since 1900, the percentage of Americans age 65 and older nearly quadrupled (from 4.1% in 1900 to 16% in 2019 ), and the number increased more than 17 times (from 3.1 million to 54.1 million).
Due to increasing life expectancy and falling fertility levels, the UN explained that for the first time in history, individuals aged 65 or above outnumbered children under five years of age globally. Moreover, by 2050, one in six people in the world will be over the age of 65 (16%), up from one in 11 in 2019 (9%).
1. By the end of this Decade of Healthy Ageing – in 2030 – the number of people 60 years and older will grow by 56 per cent, from 962 million (2017) to 1.4 billion (2030). By 2050, the global population of older people will more than double to 2.1 billion.
Much of this growth will be prompted by the aging of the Baby Boomers, who in 2030 will be aged 66 to 84—the “young old”—and will number 61 million people. In addition to the Baby Boomers, those born prior to 1946—the “oldest old”—will number 9million people in 2030.
At age 85 and older, this ratio increased to 181 women for every 100 men. Since 1900, the percentage of Americans age 65 and older more than tripled (from 4.1% in 1900 to 16% in 2018), and the number increased more than 16 times (from 3.1 million to 52.4 million). The older population itself became increasingly older.
The growth of the U.S. population age 65 and older exceeds that of the total population and the population under age 65. Lower birth rates and increased longevity have led to this rapid growth not just in the United States but across the world.
There were 703 million persons aged 65 years or over in the world in 2019. The number of older persons is projected to double to 1.5 billion in 2050. Globally, the share of the population aged 65 years or over increased from 6 per cent in 1990 to 9 per cent in 2019.
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.
The number of Americans ages 65 and older will more than double over the next 40 years, reaching 80 million in 2040. The nation is aging. By 2040, about one in five Americans will be age 65 or older, up from about one in eight in 2000.
The fastest growing segment of the older population is the oldest old — that is, those ages 85 and older.
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.
