2010 Census Resources and Connecticut Results

Census2010.jpg

On March 9, 2011, the U.S. Census Bureau released 2010 Redistricting files for Connecticut, containing a limited amount of local-level information on population, race/ethnicity, age, and housing unit counts from the 2010 Census.

Additional data from the 2010 Census will be posted at the Census Bureau's American Factfinder website, as well as on DataHaven. Specific tables by age group, race, gender, and housing type will become available on a rolling basis from the Census Bureau. Please visit the Census Bureau's 2010 Census website for the latest information, or follow them on Twitter.

DataHaven will post files and data visualizations related to the 2010 Census on this page. We encourage organizations, agencies and citizens located within the Greater New Haven and Valley Region to contact us if they need assistance with using data from the Census Bureau.

Important Note: What's New About the 2010 Census?

There are several differences between the 2010 Census and previous Censuses. The Census "long form," which was used to collect data for the 2000 Census as well as previous Decennial Censuses, provided a 1-in-6 population sample of demographic and socioeconomic characteristics such as educational attainment, commuting, income, housing costs, and poverty. This form is no longer collected as part of the Decennial Census, and instead has been replaced by the American Community Survey (ACS). The ACS is a nationwide, continuous survey designed to provide reliable and timely demographic, housing, social, and economic data every year. The 2005-2009 5-Year ACS provides an approximately 1-in-9 population sample, collected over 5 years, that may be used to changes in these data at a local level since 2000. 3-Year and 1-Year ACS samples are also available, but are subject to larger margins of error and only provide data for larger geographies such as counties and large cities.

2010 Social, Housing, Demographic, and Economic Data Profiles

Links to the most recent town- and county-level Census socioeconomic data profiles are posted on our website at this page. These are from the ACS (see above). Various indicators from the American Community Survey and Census are also being posted on DataHaven's indicator page. Please contact us if you can't find what you need.

Connecticut Data Visualizations

The following pilot data visualizations are developed using the Weave platform developed by the Open Indicators Consortium (OIC) working with faculty and students at the University of Massachusetts Lowell. The Connecticut Data Collaborative is a founding member of the OIC and DataHaven is working closely with the Partnership to develop their statewide project at http://www.CTData.org.

These visualizations may take a minute to load - please be patient. Depending on your system settings, you may need a modern internet browser and/or updated version of Adobe Flash to view these.

Total Population: Percentage Change in Population, 2000-2010

This map and data table, available at the County Subdivision level, allows users to select geographies within the table or by clicking on the map. Scroll over each town to view its characteristics. Colors are based on % population change since the 2000 Census. The population of the State of Connecticut as a whole in the 2000 Census was 3,405,565. The state's population increased by 4.9% between 2000 and 2010, to 3,574,097.

You may click on any column in the Data Table to sort by that indicator. You may also be able to download an image (jpg) using the "Export" button. We expect that these tools will be significantly improved over time as the Open Indicators Weave platform is developed.

Visualizations of Change in Race and Hispanic/Latino Population, 2000-2010

We have developed visualizations of the 2010 Census Data by Race and Ethnicity at this page. Here you may view:

  • Total Change in Hispanic or Latino Population (of any Race), 2000-2010
  • Total Change in White, Not Hispanic Population, 2000-2010
  • Total Change in Black or African-American, Not Hispanic Population, 2000-2010
  • Total Change in Asian, Not Hispanic Population, 2000-2010

Other Demographics Resources and Future Visualizations

Please see our page on Demographic Data and Indicators for links to other statewide and national data sources, including those compiled by DataHaven. Please contact us with any questions -- our resource collection expands in large part based on requests from our users.
