The 2010 Census counted 53,364 people age 100 and older in the United States, and they were overwhelmingly female. For every 100 centenarian women, there were only 20.7 centenarian men.

These figures come from a special report based on the 2010 Census that provides a portrait of the centenarian population in the United States describing their age, sex, race, Hispanic origin and living arrangement characteristics. The report, Centenarians: 2010, also compares centenarians with other age groups in the older population.

According to the report, the population 100 and older made up a small proportion of the total U.S. population — representing less than two per 10,000 people. Centenarians represented 19 per 10,000 people who were 70 and older. More than half (62.5 percent) of centenarians were age 100 or 101 while roughly 92 percent were ages 100 to 104. Supercentenarians — those ages 110 and older — represented 0.6 percent of the centenarian population.
