Livability's Matt Carmichael maps the various pockets of the country where people are growing older, getting richer, or becoming more diverse.
According to recently released 2010-2014 U.S. Census Bureau data (which Carmichael compares with the previous five year period of 2005-2009), as the population gets older, people across the country are choosing to age-in-place in their communities—which is an important to consider when planning housing and cities. Only one in five counties show a an increase in the share of children among the population increase, suggesting that people are having fewer children, and having them later in life.
Where did America grow more diverse? In nearly 90% of counties the Hispanic population grew. However it grew to uneven extents. In the 2009 map, there are not unexpected concentrations in the southwest and west. But if you look closely, you start to see some of the orange areas creep up into the yellow. Some of the blues shift darker. And some of the dark blues pop to purple. In five years, this will shift even further, partially due to the increase in sheer numbers and partially due to the aging of the non-Hispanic population. Those two things will yield bigger and bigger shares in counties throughout the U.S.
