Many Connecticut Cities and Towns participated in the Local Update of Census Addresses (LUCA). CtSDC thanks these communities for helping to assure an accurate and authoritative count that is the basis for significant federal-to-state funding that flows into Connecticut.
A 2010 Census Planning
Document is in its initial stages. It is initially based on 2000 Census tract data, and will be updated to
include ACS data from 2005 and 2005 and other releases, as they become available.

User Guide to the Census Bureau
The U.S. Census Bureau serves as the leading source of statistical data about our nation's people and its economy, under Title 13 of the the United States Code. A thorough illustration of the data types and their uses is included in the Census Bureau submission to Congress of its Subjects Planned for the 2010 Census and the American Community Survey (ACS).
Under its current charter, Census distributes surveys for information to individuals and businesses, schools and farmers, in every state almost every day of the year. The final page of the Abstract of Demographic Surveys lists Contact names for each of the thirty-one (31) on-going surveys.
Comparing American Community Survey with Decennial Census data
The U.S. Census has been capturing and distributing information about residents, both
(1) how many of us there are, and (2) major characteristics we share, in the categories of population and housing.
During the second half of the 20th Century, we remember both the
(a) the short form (called "100%-Data", since every household is included) and (b) the long-form
(called "Sample Data", since it is distributed to approx. 1 in 6 households). {See middle of this
American FactFinder website for a fuller description.}
ACS, as a survey of demographic, social, economic and housing characteristics, is only in the middle of its 8-year start-up process, which will culminate in 2010, with its first complete set of "sample data". Rather than sampling only every ten years, surveys are distributed (a) every year for communities and counties above 65,000, (b) every two years for entities between 20,000 and 65,000 people, and (c) every five (5) years for entites below the 20,000 threshold. Executing these multiple survey instruments in the state of Connecticut employs approximately 50 people. Upwards of 650 people do Census work in New England.
PLEASE NOTE that some survey questions and their resulting data collection have been changed from the 2000 Census and between a number of ACS surveys. Please review the following data comparison charts (and associated pages) before setting up comparisons.
- Guidance on Comparing 2006 ACS Data to Other Sources
- Papers and Presentations about ACS vs. Census Methodology
- N.Y. State SDC comparison between Census 2000 and ACS 2005 fields.
- NSF Panel review of ACS, Preliminary, prepub version
- ACS vs. Census CPS "estimates" program, see next paragraph.
To find each Connecticut's individual town population, go to the
Subcounty Population Tables. One last CAUTION is
that 2006 ACS includes Group Quarters counts in the total ACS populations,
while for previous years, ONLY household counts were reported.
Data Distribution Service for other Agencies
In addition to its core deliverables, Census performs work under reimbursement agreements for
USDA, DOL, HHS, HUD, DOE, and DOJ; the Bureau of Justice Statistics (BJS), the National Center for
Education Statistics (NCES), the Bureau of Transportation Statistics (BTS),
EPA (Environmental Protection Administration), and
the Agency for Health Care Research and Quality (AHCRQ). Census also develops statistics that are
used by the Department of Education Title I office of "No Child Left Behind".
Furthermore, Census serves as a data conduit for other statistics sources, such as the
Centers for Disease Control(CDC).
Did Census Contact You?
The U.S. Census Bureau has replaced the "long form" survey, that was part of the every-ten-year Census survey, with the American Community Survey (ACS). Now, every year, the Census Bureau will be contacting between 2- and 5-% of a state's population, and asking them to complete a survey which is equivalent to the long-form.
The Census Bureau website, Are You in a Survey? answers basic questions about participating in a survey, whether through a mail-in questionnaire, on the telephone or with a Census representative on your doorstep.
If you have concerns about completing any official Census survey, call the
following 800 number, to talk with a Census representative:
1-800-562-5721
If you need additional assistance clarifying a situation, please contact our Connecticut State Data Center staff (see in Contacts below) or the Census Regional Office in Boston, , to discuss any concerns about the surveys in New England.
