U.S. Census Bureau estimates released Wednesday show Illinois' population fell by 33,703 people between July 1, 2016 and July 1 of this year. The state now trails Pennsylvania in population by about 3,500 people, making Illinois the sixth-most-populous state in the U.S.
Illinois was among eight states that saw their population fall, and lost more people than the seven other states that dropped. The decrease was a tiny fraction of Illinois' total population of just over 12.8 million.
States in the west and south saw the greatest population growth. The fastest-growing state was Idaho, followed by Nevada, Utah, Washington, Florida and Arizona.
Wyoming saw the largest percentage decline.
