Population Change in America

Population growth in the United States continues to fall. According to the Census Bureau since Census Day (April 1) 2010, the population of the U.S. has grown by 21,476,884 or 6.96%. However in 2019 in forty-two states (and the District of Columbia) there were fewer births than there were in 2018. Only eight states saw a birth increase last year. The falling birth rate and increasing number of deaths means that although the population has grown there has also been a decline in 'natural increase' (or births minus deaths) over the last decade.

You can explore population change over the last ten years across the whole of the United States on this Population Change interactive map. The map visualizes where the population has grown and fallen over the last decade at the zip-code level. The map uses census data to show which neighborhoods have seen the biggest increase in population and which have seen a drop in population.

When zoomed out on the map you can tell that Texas and Florida in particular are two states which have seen high levels of population growth over the last ten years. However, if you zoom in on the map, you can explore population change at a far more local level. The map sidebar provides a number of quick links to zoom the map to a number of cities which have seen interesting developments in population over the last 20 years.

You can explore the map in even more detail by zooming in on zip-code areas. Click on a zip-code area on the map and you can view the local population in 2010 and 2019 and the percentage by which the population changed over this period.
