2011 American Community Survey Release Schedule

The U.S. Census Bureau schedule for the release of the American Community Survey data for 2011 starting in September of 2012 is now available. Included below are details on each release so be sure to make your calendars as this data will be available via the American FactFinder website once the data is released.

2011 American Community Survey — The Census Bureau plans to release one-year estimates from the 2011 ACS on Thursday, Sept. 20, 2012. The ACS produces estimates for numerous social, economic and housing characteristics including language, education, the commute to work, employment, mortgage status and rent, as well as income, poverty and health insurance. Embargo subscribers will have access on an embargoed basis to the estimates beginning Tuesday, Sept. 18. Estimates will be available for the nation, all 50 states, the District of Columbia, Puerto Rico, every congressional district, every metropolitan area, and all counties and places with populations of 65,000 or more. In June 2011, the ACS annual sample size was increased from 2.9 million to 3.54 million addresses, which should result in an improvement in the reliability of the estimates.

On Sept. 20, the Census Bureau will also release the first in a series of short briefs that analyze a wide range of topics. Additional briefs will follow. Each year, the Census Bureau varies the topics of these short briefs.

2009-2011 American Community Survey — The Census Bureau plans to release the three-year estimates from the 2009-2011 ACS on Oct. 25, 2012. Embargo subscribers will have access to the estimates up to 48 hours in advance of the public release. The estimates will cover all geographic areas with populations of 20,000 or more. They will include the first set of three-year estimates for field of degree of bachelor’s degree holders.

2007-2011 American Community Survey — The Census Bureau plans to release the five-year ACS estimates covering 2007-2011 on Dec. 6, 2012. Embargo subscribers will have access to the estimates on Dec. 4. These estimates are available for all areas regardless of population size, down to the block group.
The ACS Public Use Microdata Sample (PUMS) files for each of the three sets of statistics will be released one to two months after each public release.

U.S. Census Bureau API now available

The U.S. Census Bureau has released an Application Programming Interface (API) to enable developers to create applications for the web and mobile platforms to enable users to explore census data via customized interfaces. The API enables developers to access the 2010 Census (Summary File 1) and the 2006-2010 American Community Survey (ACS) 5 Year Estimates allowing users to view data on population, age, sex, race, Hispanic origin, households, education, income, employment, commuting, occupations, housing, and more.

The U.S. Census Bureau has developed an “App Gallery” which will feature applications developed using the API. Currently there are two examples in the App Gallery that provide examples of the potential for using the Census API. These applications include:

  • Age-Finder – enables users to count population for single years or for a range of customized age ranges. 
  • Poverty Map – provides poverty statistics from the American Community Survey for New York state and includes an visualization of margin of error and more.

Want to explore the Census API and develop your own application? Developers can access the Census Bureau API at: http://www.census.gov/developers/.  Have an idea for an application using the API? Share your ideas through the Census Bureau’s Developers Forum.

Try out the Census Bureau API and if you create something be sure to share it with the U.S. Census Bureau. Enjoy!

V. Projects in Progress – July 2012
Each month the students and staff at MAGIC and the Connecticut State Data Center are working on a series of projects, tasks, data sets, and resources which users typically don’t know about until we add the resource to our website. Included below is a list of projects that are currently underway which will be completed in the coming months and made available in their final forms via our websites.

  • Connecticut Population Projections 2015-2025 – This project involves developing updated population projections based on the 2010 Census, Birth and Mortality data from the Connecticut Department of Public Health, and developing derived migration based on these data for multiple levels of geography. Over the past month we have been refining the methods by incorporating additional data which will enable additional age groupings to be provided while also providing the ability to calculate more detailed rates of survival to improve the projections. Throughout this process we have been preparing scripts to help process the data for the projections which will enable future updates to be conducted on an annual basis (if necessary). This project is still underway and the public is able to view a preliminary version (population estimates are subject to change as we refine the methods over the next month). View the preliminary projections and the interactive data interface at: http://ctsdc.uconn.edu/projections.html
  • Data Visualization – This project involves testing new tools and methods for visualizing data at the Connecticut State Data Center and MAGIC. Testing has included Tableau, Google Fusion Tables, and ArcGIS Online to determine which solution(s) are best depending upon the data visualization needed (maps, graphs/charts, or combinations).
  • Google Floor Maps – in collaboration with colleagues from the UConn Libraries Undergraduate Education team, we have begun developing updated floor maps for the storrs campus libraries (regional campuses will be included at a future date) to contribute these maps to the Google Maps Floor maps for Android. We have uploaded our first map and once approved, google maps users will be able to view a generalized floor map to help navigate public areas within the building. Learn more about this in the following article from Wired.
Have an idea for a project or suggestions for improvements to MAGIC and the Connecticut State Data Center’s website and web offerings? Leave us a comment or contact us at magic@uconn.edu.  





Each month we will be posting a “Month in Review” article so check back next month to see the latest information on usage trends at MAGIC and the Connecticut State Data Center.
