These are the nations that number more than 100.

The top four places with the most centenarians are all island nations, according to a study by Luty, a digital marketplace for older adults seeking care. First place goes to Guadeloupe, an archipelago in the Caribbean with 299 centenarians – or 75 per 100,000 people. This is a nearly 80 percent increase since 2000.

The French mainland is followed by its Caribbean neighbors – Barbados and Martinique – in second and third place respectively. Barbados has 71 centenarians per 100,000 and Martinique has 63. Japan and Uruguay are fourth, each with 62 more than 100 people per 100,000.

The United States came in 11th with 29 centenarians per 100,000 people. In total, there are 97,104 people over the age of 100 living in the U.S. – an increase of 58{239e285f263255a4def39786004ab453a8a476bcb9996e0d54e1ce7666739355} over the past two decades.

The US territory of Puerto Rico fared even better than the mainland. Coming in sixth, the Caribbean island has 1,660 centenarians, of which about 74{239e285f263255a4def39786004ab453a8a476bcb9996e0d54e1ce7666739355} are women and 26{239e285f263255a4def39786004ab453a8a476bcb9996e0d54e1ce7666739355} are men. The number of people over 100 in Puerto Rico has increased by 67 percent since 2000.

The data used for the study was collected in 2020, and every place in the top 15 has seen an increase in the number of centenarians since 2000. The largest percentage increase came from Hong Kong, which was at number 7. The 100-year-old population increased by nearly 90 percent — with 3,561 centenarians living in the Chinese region.

Every country in the survey saw more women than men living up to 100. Barbados has the lowest gender gap, with about 46 percent of centenarians male and 54 percent female. The largest margin is in Uruguay, where nearly 90{239e285f263255a4def39786004ab453a8a476bcb9996e0d54e1ce7666739355} of centenarians are women and only 10{239e285f263255a4def39786004ab453a8a476bcb9996e0d54e1ce7666739355} are men.
