MUNICIPALITIES:
Redistricting After a Special Census
The Honorable Patricia Reid Lindner
Assistant Republican Leader
State Representative, 50th District
32 Main Street, Suite A
Sugar Grove, Illinois 60554
Dear Representative Lindner:
I have your letter inquiring whether a municipality that is required to redistrict as a
result of a special census may, pursuant to subsection 3.1-20-10(b) of the Illinois Municipal Code
(the Municipal Code) (65 ILCS 5/3.1-20-10(b) (West 2006)), adopt an ordinance providing for
fewer aldermen than the number fixed by statute for municipalities of that population. For the
reasons stated below, it is my opinion that subsection 3.1-20-10(b) is applicable only to
municipalities redistricting "following the *** receipt of the new federal decennial census
results[.]" Therefore, a municipality that redistricts on the basis of the results of a special census,
rather than a Federal decennial census, may not adopt an ordinance restricting the number of
aldermen under subsection 3.1-20-10(b).

BACKGROUND
Your district includes the United City of Yorkville (Yorkville), a municipality
located in Kendall County. In the 2000 Federal decennial census, Yorkville's population was
6,189. Illinois Blue Book 455 (2003-2004). Based on information that you have provided,
Yorkville's current population is 11,204,¹ and, accordingly, the city currently has eight aldermen.²
Yorkville has requested a special census and anticipates that it "will yield a population count
greater than 15,000[.]"
Pursuant to subsection 3.1-20-25(c) of the Municipal Code (65 ILCS 5/3.1-20-
25(c) (West 2007 Supp.)), a city council must immediately redistrict a city's wards if the results
of an "official census" show, among other things, that the city's population has increased to a size
that requires a greater number of aldermen. A special census is considered an "official census."
13 U.S.C.A. §196 (West 1990) (authorizing the Secretary of Commerce to conduct special
censuses for municipalities on a cost-reimbursable basis, and providing that "[t]he results of each
such special census shall be designated 'Official Census Statistics"). Cities of more than 15,000
but less than 20,000 inhabitants must elect ten aldermen. 65 ILCS 5/3.1-20-10 (West 2006).
Therefore, assuming that Yorkville's special census reflects the anticipated increase in
population, you have inquired whether, pursuant to subsection 3.1-20-10(b), Yorkville may adopt
an ordinance establishing its number of aldermen at eight, rather than ten.
'We will assume that Yorkville previously contracted for the conduct of a special census.
²Illinois law generally requires eight aldermen to be elected in cities exceeding 3,000 but not
exceeding 15,000 inhabitants. 65 ILCS 5/3.1-20-10 (West 2006).

ANALYSIS
Section 3.1-20-10 of the Municipal Code (65 ILCS 5/3.1-20-10 (West 2006))
provides:
(a) Except as otherwise provided in subsections (b) and (c)
of this Section, Section 3.1-20-20,¹³ or as otherwise provided in the
case of aldermen-at-large, the number of aldermen, when not
elected by the minority representation plan, shall be as follows: in
cities not exceeding 3,000 inhabitants, 6 aldermen; exceeding
3,000 but not exceeding 15,000, 8 aldermen; exceeding 15,000 but
not exceeding 20,000, 10 aldermen[.] ***
(b) Instead of the number of aldermen set forth in
subsection (a), a municipality with 15,000 or more inhabitants may
adopt, either by ordinance or by resolution, at least 180 days prior
to the first municipal election following the municipality's receipt
of the new federal decennial census results, the following number
of aldermen: in cities exceeding 15,000 but not exceeding 20,000,
8 aldermen[.] (Emphasis added.)
The primary objective of statutory construction is to ascertain and give effect to
the intent of the General Assembly. The most reliable indicator of legislative intent is the
statutory language itself. Where the language is clear and unambiguous, it must be applied as
written, without resort to extrinsic aids to statutory construction. People V. Perry, 224 Ill. 2d
³Subsection 3.1-20-10(c) (65 ILCS 5/3.1-20-10(c) (West 2006)) authorizes municipalities with
between 40,000 and 50,000 inhabitants to adopt an ordinance or resolution increasing the number of aldermen from
14 to 16.
Section 3.1-20-20 (65 ILCS 5/3.1-20-20 (West 2006)) permits cities with fewer than 100,000
inhabitants to reduce, pursuant to referendum, the number of aldermen to one-half the total authorized by section 3.1-
20-10 or to reduce the number of aldermen to one alderman per ward plus an additional number of aldermen at large.

312, 323 (2007). Further, statutes must be construed so that each word, clause, and sentence is
given a reasonable meaning and not rendered superfluous. Lohr V. Havens, 377 Ill. App. 3d 233,
237 (2007), appeal denied, 226 III. 2d 616 (2008).
Assuming that the special census shows that the population of Yorkville has
increased to between 15,000 and 20,000 inhabitants, subsection 3.1-20-10(a) will require
Yorkville to increase its number of aldermen from eight to ten, unless otherwise excepted.
Under subsection 3.1-20-10(b), a municipality with a population of between 15,000 and 20,000
inhabitants may establish its number of aldermen at eight, if the municipality adopts the
necessary ordinance "at least 180 days prior to the first municipal election following the
municipality's receipt of the new federal decennial census results[.]" (Emphasis added.)
Subsection 3.1-20-10(b) expressly references the receipt of "new federal decennial census
results[.]" Although a special census may be an "official census," it is not a "federal decennial
census." Accordingly, under the plain and unambiguous language of subsection 3.1-20-10(b),
Yorkville is not authorized to adopt an ordinance to establish the number of aldermen at eight
based on the results of a special census. To construe the language of subsection 3.1-20-10(b)
otherwise would render the term "federal decennial census" superfluous. This interpretation is
4Under Federal law, the Secretary of Commerce is required to take a decennial census of the
population as of the first day of April "in the year 1980 and every 10 years thereafter[.]" 13 U.S.C.A. §141 (West
1990). The most recent Federal decennial census was conducted in the year 2000.
13 U.S.C.A. §196 (West 1990) authorizes the Secretary to conduct a special census for cities or
other political subdivisions within a state upon payment of the costs of conducting the special census. Results of
such special census may be designated as "Official Census Statistics" and may be used in the manner provided by
applicable law.
The Honorable Patricia Reid Lindner - 5
consistent with other provisions of the Municipal Code (65 ILCS 5/1-1-1 et seq. (West 2006)) in
which the General Assembly has expressly directed that the results of an official census - and not
a Federal decennial census - be used for a particular purpose. See, e.g., 65 ILCS 5/3.1-20-25
(West 2007 Supp.) ("Whenever an official census shows that a city contains more or fewer wards
than it is entitled to, the city council *** shall redistrict the city") (emphasis added); 65 ILCS
5/3.1-20-30 (West 2006) ("After an official census is officially published, if a city is divided into
a greater number of wards and has elected a greater number of aldermen than the city is entitled
to *** all acts, resolutions, and ordinances of the city council *** are valid") (emphasis
added); contra 65 ILCS 5/7-6-7 (West 2006) ("If *** there is in existence any municipality in
which the Bureau of the Census did not determine the population when the last preceding
decennial census was taken, the county board of the county in which such municipality is located
may *** arrange with the Bureau of the Census to take a special census of such municipality").
CONCLUSION
Because subsection 3.1-20-10(b) of the Illinois Municipal Code is expressly
limited to redistricting based on the receipt of "new federal decennial census results,"
municipalities that are required to redistrict based on the results of other types of censuses may
not, pursuant to this subsection, adopt an ordinance establishing the number of aldermen at a
figure below the statutorily required number. Therefore, it is my opinion that a municipality
which redistricts as a result of a special census must establish the number of aldermen in
accordance with subsection 3.1-20-10(a) of the Municipal Code.
The Honorable Patricia Reid Lindner - 6
I would further note, however, that there is no significant distinction between the
redistricting required by the results of a special census, in contrast to the redistricting required by
the results of the Federal decennial census, that would argue against permitting municipalities
that conduct a special census to adopt an ordinance providing for fewer aldermen than the law
would otherwise require. Accordingly, in light of the rapid population growth in Kendall County
(and other metropolitan areas of this State), the General Assembly may wish to consider whether
to amend the provisions of subsection 3.1-20-10(b) of the Municipal Code to apply to
redistricting based on any official census results, including special censuses conducted during the
period between Federal decennial censuses.
Very truly yours,
