NPG created this interactive U.S. population map to stimulate greater interest in population issues at the state level. It illustrates how population growth effects each state now, and – in many cases – how it will have an even more devastating effect in the future.

Visit our map often, as we will continually update it to reflect the most recent data available! Currently, our map reflects figures from the 2010 Census.
