Figures)
Overall, from
1990 to 2000 the Illinois population grew 8.6 percent.
Urban areas of the state, that is, Metropolitan Statistical
Areas (MSAs), grew much faster than rural areas. Among the
fastest growing urban areas were Bloomington-Normal,
Rockford, and Chicago, each having double-digit growth
rates. Rural areas of the state grew by just over one
percent during the decade. Only one urban area, Decatur,
had fewer residents in 2000 than in 1990.
Among Illinois' 102 counties, 17 had growth rates exceeding
10 percent. The top three were McHenry (41.9 percent
increase), Will (40.6 percent), and Kendall (38.4 percent),
all in the Chicago metropolitan area. Other counties in the
top 10 were Boone, in the Rockford MSA (35.6 percent); Kane
(27.3 percent) and Lake (24.8 percent), in the Chicago MSA;
Monroe (23.2 percent) in the St. Louis area; two rural
counties, Brown (19.1 percent) and Bond (17.6 percent); and
lastly, McLean county (16.5 percent) from the
Bloomington-Normal MSA.
There were 34 counties with fewer residents in 2000 than in
1990. All but three were rural counties. The urban counties
with a population decline were Henry in the Davenport-Rock
Island-Moline MSA, Macon, which comprises the Decatur MSA,
and St. Clair in the St. Louis MSA. No county lost more
than 10 percent of its residents, but the following rural
counties had declines exceeding five percent: Hancock,
Edwards, McDonough, Gallatin, White, Hardin, and Alexander.
