U.S. - seniors as a percentage of the population 1950-2050

In 2022, about 17.3 percent of the American population was 65 years old or over; an increase from the last few years and 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 rapidly aging population In recent years, the aging population of the United States has come into focus as a cause for concern, as the nature of work and retirement is expected to change in order to keep up. If a population is expected to live longer than the generations before, the economy will have to change as well in order to fulfill the needs of the citizens. In addition, the birth rate in the U.S. has been falling over the last 20 years, meaning that there are not as many young people to replace the individuals leaving the workforce. The future population It’s not only the American population that is aging -- the global population is, too. By 2025, the median age of the global workforce is expected to be 39.6 years, up from 33.8 years in 1990. Additionally, it is projected that there will be over three million people worldwide aged 100 years and over by 2050.

于2022年，美国总人口中65岁及以上的人口比例约为17.3%，相较于往年有所上升，且这一比例预计到2050年将达到22%。相较于1950年时仅8%的人口比例，这一增长显著。近年来，美国人口的快速老龄化问题日益引起关注，鉴于工作性质和退休方式的预期变化，这一现象成为了一个值得关注的焦点。若预期人口寿命将超过前几代人，经济结构亦需相应调整，以满足公民的需求。此外，美国在过去20年中出生率持续下降，意味着年轻一代的人数不足以替换退出工作队伍的人口。展望未来人口，老龄化问题不仅限于美国，全球人口亦然。预计到2025年，全球劳动力的中位年龄将达到39.6岁，相较于1990年的33.8岁有所上升。此外，预计到2050年，全球百岁以上的人口将超过三百万。
