The Growing Number of Centenarians
Living to 100 is becoming increasingly common. In the US, the number of centenarians has been growing rapidly — from about 50,000 in 2000 to over 90,000 today. Projections suggest this number could reach 600,000 by 2060.
Countries like Japan, Italy, and Monaco have the highest concentrations of centenarians. Okinawa, Japan, is famous for its high number of people living past 100, often attributed to diet, exercise, and social connections.
Whether you'll reach 100 depends on many factors including genetics, lifestyle, diet, exercise, and access to healthcare. This calculator gives you a fun way to see your century birthday date!
