Data Release Schedule:
The 2010 Census data will be released in phases. As mandated by law, the national and state population counts must be delivered to the President of the United States by December 31st. This data is used for congressional apportionment. Some states will likely gain (or lose) seats in the U.S. House of Representatives based on the 2010 Census count. By March 31, 2011, the Census Bureau will release more detailed data to help states redraw congressional, state, and local legislative district boundaries in the process called “redistricting”. All 2010 Census data will be available on the Census Bureau’s new database website: http://www.factfinder2.census.gov

2010 Census Challenge Programs:
There are two programs the Census Bureau offers for challenging the decennial Census counts:
Count Question Resolution Program
Program runs June 1, 2011 – June 1, 2013
Governmental units can challenge the 2010 counts of housing units and group quarters, including:
Boundaries – challenges related to inaccurate reporting or the inaccurate recording of boundaries legally in effect on January 1, 2010
Geocoding – challenges related to the placement of living quarters and associated population.
Coverage - challenges, that if upheld by the Census Bureau, result in the addition or deletion of specific living quarters and persons associated with them identified during the census process, but erroneously included as duplicates or excluded due to processing errors.
There are no costs associated with this program other than administrative costs and staff time.

Special Census
Program available approximately one year after the 2010 Census
A Special Census is a basic enumeration or count of population, housing units, and group quarters conducted by the Census Bureau at the request of a governmental unit for the entire governmental unit geography, including newly annexed areas or a portion of the governmental unit geography.
The governmental unit is responsible for the cost of conducting a Special Census and may request a cost estimate from the Census Bureau ($200 fee to request). The cost is based on the estimated increase in population. For example, the City of Eldridge requested a Special Census in 2004, resulting in a gain of 648 persons. The special census cost the City approximately $77,000. However, they were able to justify this by estimating an increase in road use tax funds alone that would recoup the cost in one to two years.
For more information visit: http://www.census.gov/regions/specialcensus/
Both programs require fairly detailed information and study related to the costs and benefits. Detailed Census information is needed for population and housing units at the Census block level.
Operational Milestones:
Complete Questionnaire Data Capture and Processing - COMPLETE
Once the Census Bureau receives completed questionnaires the data is put into an electronic format, processed and then tabulated in order to provide state population totals necessary for apportionment.
Quality Assurance Operations - COMPLETE
The Census Bureau will conduct three major quality assurance operations and other processes to ensure that the 2010 Census is accurate and complete.
• Coverage Follow Up Operation (4/11/10 – 8/13/10) - During this operation, the Census Bureau will call households who have responded but there are questions regarding the answers on the form.
• Vacant Delete Check (7/24/10 – 8/25/10) - Additional information is collected to ensure that housing units classified as vacant (or nonexistent) were in fact unoccupied on April 1st.
• Field Verification (8/6/10 -9/3/10) - The Census Bureau verifies whether or not an address exists and confirms its geographic location if it does not match an address in their files. These addresses are from those households who submitted a census form without an identification number linked to the Census Bureau’s address files.
Door-to-Door Follow up Phase – COMPLETE
Census takers visited roughly 47 million households that did not mail back their questionnaire (or who did not receive a form delivered to them).
Form Delivery and Mail Back Phase – COMPLETE
The 2010 Census mail out was the largest single delivery ever undertaken by the United States – over 120 million forms were mailed in March 2010. Additional forms were sent to increase mail back participation in low responding areas.
Address Verification – COMPLETE
Approximately 140,000 Census Bureau employees checked 145 million addresses from March through July 2009.
About 2010 Census:
What
Count
The Census is a count of everyone residing in the United States: in all 50 states, the District of Columbia, Puerto Rico and the Island Areas.
Who
Everyone
All residents of the United States must be counted. This includes people of all ages, races, ethnic groups, citizens and non-citizens.
When
Every 10 years
Every 10 years, and the next census occurs in 2010. Census questionnaires will be mailed or delivered to every household in the United States in March 2010. The questions ask you to provide information that is accurate for your household as of April 1, 2010.
The Census Bureau must count everyone and submit state population totals to the U.S. President by December 31, 2010.
The first Census was conducted in 1790 and has been carried out every 10 years since then.
Where
Everywhere in the U.S.
The census counts everyone residing in the United States: in all 50 states, the District of Columbia, Puerto Rico and the Island Areas.
People should be counted where they live and sleep most of the year.
Why
The U.S. Constitution (Article I, Section 2) mandates a headcount of everyone residing in the United States. The population totals determine each state’s Congressional representation. The numbers also affect funding in your community and help inform decision makers about how your community is changing.
How
The Census Bureau will mail or deliver questionnaires to your house in March 2010. A second form will mailed to households that do not respond to the initial questionnaire.
Bi- State’s Role in the 2010 Census:
Bi-State Regional Commission has pledged to be a 2010 Census Partner in both Iowa and Illinois and has adopted a resolution in support of the 2010 Census. In doing so Bi-State staff plans the following activities:
• Act as an intermediary contact between the Census Bureau and local governments and other affiliates that would like assistance being involved in the 2010 Census;
• Provide resources and information (including promotional materials as available), and participate in Census activities;
• Create a 2010 Census page on the Bi-State Regional Commission website.
• Encourage participation and cooperative coordination among the local governments, and hold quarterly meetings for Complete Count Committees to coordinate activities and share ideas.
