How many people in the U.S. are over the age of 60? How many over the age of 70?

The census has a page [
http://www.census.gov/population/www/socdemo/age.html ] with links to
exactly the information you are looking for (and other similar
statistics. The census 2000 gateway page [
http://www.census.gov/main/www/cen2000.html ] says that "The
population of the U.S. on April 1, 2000 was 281,421,906" The page that
mentions population by age can be found on the following page: [
http://www.census.gov/population/www/cen2000/phc-t9.html ],
specifically, I consulted the linked file here [
http://www.census.gov/population/cen2000/phc-t9/tab01.txt ], which
stated that for the 2000 census, the following age groups had the
following population in the US:

60 to 64 years            10,805,447
65 to 69 years             9,533,545
70 to 74 years             8,857,441
75 to 79 years             7,415,813
80 to 84 years             4,945,367
85 years and over          4,239,587

So to answer your question specifically, there are 45,797,200 persons
in the united states over 60 years of age, and 25,458,208 persons over
the age of 70.

Now that it is late 2002, it would be reasonable to round up to 46
million (over65) and 25,500,000 for over 70. The number in these older
groups increases very slowly, most years.   Neil

That should have been over 60, not over 65.  Neil
