Today is May Day, an unofficial holiday that many older people remember with pleasure.
So it’s only fitting that the entire month of May is Older Americans Month, a time to celebrate those 65 and older through ceremonies, events and public recognition.
Here’s a look at the nation’s older people by the numbers, courtesy of the U.S. Census Bureau:
41.4 million — The number of people who were 65 and older in the United States on July 1, 2011, up from 40.3 million on April 1, 2010 (Census Day). In 2011, this group accounted for 13.3 percent of the total population.
92 million — Projected population of people 65 and older in 2060. People in this age group would comprise just over one in five U.S. residents at that time. Of this number, 18.2 million would be 85 or older.
2.4 million — Projected number of baby boomers in 2060. At that time, the youngest baby boomers would be 96 years old.
2056 — The year in which, for the first time, the population 65 and older would outnumber people younger than 18 in the U.S.
Nearly 17 percent — Projected percentage of the global population that would be 65 and older in 2050, up from 8 percent today.
In 2005, Europe became the first major world region where the population 65 and older outnumbered those younger than 15.
By 2050, it would be joined by Northern America (which includes Canada and the United States), Asia, Latin America and the Caribbean and Oceania (which includes Australia and New Zealand).
$33,118 — The 2011 median income of households with householders 65 and older, not significantly different from the previous year
