Re: District of Columbia Count Question Resolution Challenge
Dear Challenge Staff:
As the Mayor of the District of Columbia, I am submitting a cha llenge of the District's 2010 Census
Red istr icting Data (Public law (P .L.194·171). Th is letter and the enclosed documents are being submitted to
the U.S . Cen sus Bureau's Count Qu est ion Resolution (CQR) p r o g r ~ m for th e purpose of this challenge.
Complete and acc urate data from the decennial census co unt are central to our democratic system of
governmen t. As required by the Constitution, Census results are used to apportion seats in the U.S. Hou se of
Representatives, to redraw con gressiona l and legislative d is tr ict s, allocate billions of dollars in federal
assistance to states and local governm en ts, and for many other publiCand pr ivate sector purposes. While we
applaud the U.S. Ce nsus Bureau on conducting a very succes sful 2010 Census, we afe also aw are that failure
to delive r quality data could skew the eq uitable distribution of political power, impair pub lic and privat e
decision making, and erode public co nfidence in Censu s data . The D.C Office of Planning's State Data Cent er
co nducted a rev iew of the District's 2010 Cens us Redistricting Data and identifi ed severa l instances wh ere
the District's hou sing units and population appear to hav e been ass igned to the wrong census blocks and /o r
incorrectly tabulated.
As permissib le under the Count Ques ti on Resolution progra m, I am requesting: 1) geocoding corrections
where the Bureau placed the living qu arters and their as sociated population in the wrong location, and 21
coverage corrections where the Burea u's enumeration of livin g quarters and their corres ponding population
wi thin census blocks differs substantiall y from what the Di strict believes to be the correc t number. This
challenge relat es to 549 ce nsus blocks with iss ues categorized as follows:
• The Cen sus has reported housing units in census blocks that are clea rly medians, parks, or other
places that do not actually have hOUSing units;
• The District has records of housing un its that do not appear in the Censu s records for so me census
blocks; an d
• Census co unts of housing units in some census blocks differ from those in the District's records by a
substantial number.

I urge the Cen sus Bu reau to correct these errors as soon as possible so th at the residents of the District of
Columbia are not on ly counted accurately but counted where they are actually located. I look forward to the
Bureau's full cooperation in this process, and refer you to the following individua ls as the District's point of
contacts for this challenge:
