5 things to know about population growth in your state, the country and the world

Dec 29, 2017

Illinois got smaller. Missouri got bigger (slightly). And western states seem to have a pull on people looking to relocate. That’s according to the U.S. Census Bureau's annual population estimates that were released on December 20.

To calculate growth (or shrinkage), the bureau takes into account three factors: Births, deaths and migration (people moving in and people moving out). Illinois took a hit when it comes to people leaving the state: The number births and people moving in could not make up for the 114,000 residents the state lost.

Why are people leaving Illinois? The Chicago Tribune interviewed residents who recently left the state and found a number of reasons, “from high taxes to state budget crises to crime, as well as the cold weather.”

Orphe Divounguy, chief economist with the Illinois Policy Institute told the Tribune that the state is experiencing an “out-migration crisis.” Divounguy blamed property and income taxes as contributing factors.

  1. Illinois is no longer the nation’s fifth most populous state; it was edged out of the spot by Pennsylvania. The Land of Lincoln lost more than 33,000 residents in 2017, dropping to the sixth most populous state in the union with 12,802,023 residents.
  2. Missouri grew by 22,356 people in 2017, making it the nation’s 18th most populous state at 6,113,532.
  3. The projected U.S. population on New Year’s Day is 326,971,407. This represents an increase of 2,314,238, or 0.71 percent.
  4. In January 2018, the United States is expected to experience one birth every eight seconds and one death every 10 seconds.
  5. The combination of births, deaths and net international migration will increase the U.S. population by one person every 18 seconds.
