Our new population projections over 2020, 2030, and 2040 for the nation as well as the 50 states and District of Columbia were released today. Looking forward, the U.S. population is expected to reach 383 million by 2040, but the rate of growth is projected to slow down from nearly 10% over the 2000-2010 decade to 6% between 2030-2040. Similar trends are also expected from most states.
The geographic distribution of this growing population also tells an interesting story. Back in 2000, six of the top ten largest states belonged to the North. By 2040, five of the top ten are expected to be in the South. The slowing down of the northern states along with rapid population growth in the south and west, means that over time the country will become more Southern and Western. This trend in regional population distribution is already evident from the shift in the mean center of population for the United States charted by the Census Bureau from 1790 to 2010, and will continue south-westward in the next few decades.
