WASHINGTON — Oklahoma's population grew by nearly 1 percent between July 2012 and July 2013, according to U.S. Census Bureau figures that show the state is steadily closing in on 4 million people.
Estimates released by the bureau on Thursday show the state gained 34,788 people in that time period, roughly in line with population growth in the previous two years.
The state's official population in April 2010, after the actual head count, was 3,751,351.
The Census Bureau conducts the actual count every 10 years and, in between, does surveys to estimate population growth.
According to those surveys, Oklahoma gained just more than 99,000 people between April 2010 and July 2013 and had a population of 3,850,568.
The gain over the three years was almost evenly split between migration from outside the state and births.
Population for the entire United States also grew by less than 1 percent between July 2012 and July 2013, rising from 313.8 million to 316.1 million, the Census Bureau reported.
