Iowa's population grew by about 15,000 people between mid-2012 and mid-2013, according to new government estimates.
That put the state's rate of growth about in the middle of its neighbors. Iowa grew faster than Illinois, Missouri and Wisconsin but slower than Minnesota, Nebraska and South Dakota.
The U.S. Census Bureau estimated that as of July 1, 3,090,416 people lived in Iowa. That's up from 3,075,039 the year before.
Iowa has typically been a slow-growing state, much in keeping with the rest of the region.
Since the 2010 Census, the state has added fewer than 45,000 people.
Of all the states neighboring Iowa, South Dakota grew the fastest, by 1.3 percent. Illinois grew the slowest. Its population went up just one tenth of 1 percent, to 12,882,135.
In fact, Illinois' growth was so slow that Iowa — at one quarter its size — still added more people than its neighbor to the east, 15,377 to 13,943.
The nation's fastest-growing state isn't too far from Iowa, however.
North Dakota, which is experiencing an energy boom, grew by 3.1 percent, a rate nearly five times faster than the country as a whole. It's just the latest in a three-year spurt that has boosted the state's population from 672,000 people in 2010 to 723,000 this year.
Overall, the United States grew by 2.2 million people to 316.1 million between mid-2012 and mid-2013. That's a 0.7 percent rate of growth over the 12-month period.The South and West regions grew the fastest, while the Midwest and Northeast grew the slowest.
