CHICAGO, March 15, 2006 -- Benefiting
from its proximity to large population and employment bases in
northeastern Illinois, Kendall County remained the fastest-growing county
in Illinois with a 9.4 percent population increase from July 1, 2004, to
July 1, 2005, according to estimates released today by the U.S. Census
Bureau. Kendall County, with 79,514 residents, was also the third
fastest-growing county in the nation from 2004 to 2005, and fourth
fastest-growing nationally since the 2000 Census with an overall
population increase of 46 percent.
The Census Bureau bases its new population estimates -- which use
administrative data and estimates for births, deaths and net migration --
on Census 2000 population counts updated to reflect any official census
corrections.
According
to the estimates, seven of the 10 fastest-growing Illinois counties
between 2004 and 2005 were located in the Census Bureau's
Chicago-Naperville-Joliet-IL-IN-WI Metropolitan Statistical Area (MSA).
These include Grundy County, Kendall’s neighbor to the south, ranking
second in the state at 6.5 percent; Will County, fourth at 4.1 percent;
and McHenry County, fifth at 2.6 percent. The fellow MSA counties of
DeKalb, Kane and Lake were also among the 10 fastest-growing in Illinois,
which has a total of 102 counties.

Will County, which includes the cities of Joliet, Romeoville, Plainfield
and Bolingbrook, was estimated to have gained 140,500 residents since the
2000 Census, by far the largest numerical increase posted by an Illinois
county and 11th highest among the nation’s 3,141 counties. In
the year from July 1, 2004 to July 1, 2005, Will County’s population grew
25,319, accounting for nearly half the statewide increase of 51,355.
"Will County remains well on pace to become the state’s third largest
county by 2010," said Marc Thomas, information services manager for the
Northeastern Illinois Planning Commission (NIPC). "It's
now the fourth largest in the Illinois, but by the end of this decade, it
will likely rank behind only Cook and DuPage. Rounding out the top five
Illinois counties estimated to have added the largest number of residents
between 2004 and 2005 were Lake, Kane, McHenry and Kendall Counties, each
of which added at least 6,000 more residents."
Thomas is a long-time member of the Census Bureau's officially designated
State Data Center Network (http://www.census.gov/sdc/), which is a
federal-state partnership that facilitates public access to census data.
He is also a staff member in NIPC's Data Research and Forecasting group,
which is responsible for compiling the official forecasts of population,
employment and other socio-economic indicators that are essential inputs
for transportation and land-use planning.

growth in DuPage County, one of the nation’s fastest-growing counties a
quarter century ago, has flattened out. It increased less than 1,000

Population in NIPC’s six-county service area rose 272,350 from the 2000
Census to July 2005. This accounted for four-fifths of the statewide
increase in the same period.
-
The increase in population of the five collar counties since the 2000
Census was estimated at 345,500, slightly higher than the statewide
increase of 343,700 in the same period.
-
Will, McHenry and Kane Counties are much more reliant on in-migration to
fuel growth than natural increases (births exceeding deaths). DuPage
County has joined Cook County in having more migrants who move out than
move in.

About the Northeastern Illinois Planning Commission
The Northeastern Illinois Planning Commission (NIPC) was created in 1957
by the Illinois General Assembly as the region’s comprehensive land-use
planning agency. The legislation authorizes NIPC to conduct research for
planning -- including official forecasts of population, employment, and
other socio-economic indicators -- to advise units of local government on
their plans and policies, and to provide general comprehensive plans and
policies for use by local governments. The Regional Planning Board was
established in 2005 by the Governor and the Illinois General Assembly to
better integrate planning for land use and transportation. NIPC and the
Chicago Area Transportation Study (CATS) are being consolidated within
this new, streamlined regional agency. For
