So, what explains the big increases in these somewhat unexpected places? Well, essentially, it's because there have been more deaths and fewer births elsewhere. In fact, nine states actually saw a decline in population over the last year, including New York, Illinois, West Virginia, Louisiana, Hawaii, Mississippi, Alaska, Connecticut, and Wyoming.
“Many states have seen fewer births and more deaths in recent years,” said Sandra Johnson, a demographer and statistician with Census Bureau, in a press release. “If those states are not gaining from either domestic or international migration they will experience either low population growth or outright decline.”
Overall, the US population grew by 0.6% over the last year, per the Census stats, thanks to both "natural increase" (births) and international migration. Also, while both Texas and Florida made the top 10 in terms of percentage increases in population, they took the number one spot in two other metrics. Texas had the biggest growth in terms of actual people living there (379,128) and Florida saw the biggest influx of domestic migrators (132,602).
And sure, there are lots of reasons certain states are growing fast, but hey, maybe Boise and Reno really are underrated after all.
