Technical Note:

The Population Estimates Program data used here are revised to reflect updated input data and new Census Bureau population controls. Population estimates for previous years change with the release of each new 5-year Census estimate. Since the U.S. Census Bureau revises their post-2010 estimates each year, the data presented here may differ from previously published estimates.
