WASHINGTON D.C. (WTAQ) - Wisconsinites are getting grayer -- just like other Americans. The U.S. Census Bureau says that the number of Badger State residents 65-and-older grew by 10.6% in the last decade. The Census counted 777,000 senior citizens in Wisconsin last year. That's just under 14% of the state's population. And in five-of-every-six counties, the percentage of residents 65-and-older was higher than the national average. Nationally, the 2010 Census counted 40.3 million Americans 65-and-older. That's 15-percent more than in 2000 -- higher than the nation's total population growth of nine-point-seven percent.
