By Total: California has the highest number of seniors in the U.S. with a total of 5,148,448 residents ages 65 and older. But that is likely because California also has the highest population out of the states. Second in line is Florida, with a total number of 3,926,889 seniors.
Maine has the oldest median age in the United States of 45.1 years.
Across the U.S., 52 million Americans are 65 years or older, according to the U.S. Census Bureau, and a quarter of them live in just three states: California, Florida, and Texas. By comparison, North Dakota, South Dakota, Vermont, Wyoming, and Alaska each have fewer than 150,000 senior residents.
U.S. Cities with the Oldest Population
Traditionally, the “elderly” are considered to be those persons age 65 and older. By that definition, in 1987 there were just over 30 million elderly people in the United States, more than 12 percent of the total U.S. population of nearly 252 million (Table 3.1).
The youngest state in the country is Utah, new data shows. Utah residents have a median age of 30.7 years old, younger than any other state in the U.S., according to 2016 data from the Census Bureau’s American Community Survey.
St. Augustine, founded in September 1565 by Don Pedro Menendez de Aviles of Spain, is the longest continually inhabited European-founded city in the United States – more commonly called the “Nation’s Oldest City.”
The median age in China is 38.4 years.
Over 50 million senior citizens live in the U.S., making up 16.5% of the total population. Florida has the highest percentage of senior citizens (21%), followed by Maine (20%). Utah has the lowest percentage of senior citizens (10.8%), followed by Alaska (11.1%).
