These nine states are also the most populous, and include about one-half of the total U.S. population. Sparsely populated states such as Alaska, Wyoming, Vermont, and North Dakota have very small elderly populations â less than 100,000 each in 2000.But the states with the most elderly do not necessarily have the oldest population age profiles.California is still a relatively young state even though it has the greatest number of elderly residents: Less than 11 percent of the state's total population was age 65 or older in 2000.In contrast, nearly 18 percent of Florida's population was age 65 or older, the highest proportion of any state (see table).parsely populated states such as Alaska, Wyoming, Vermont, and North Dakota have very small elderly populations â less than 100,000 each in 2000. But the states with the most elderly do not necessarily have the oldest population age profiles.
