For the approximate largest 3,300 school districts with population 20,000 and over, wide-ranging demographic updates are available (as of 12/8/08) from the 2005-07 "3-Year" Census Bureau American Community Survey (ACS). A main importance of these data is that they are the first set of wide-ranging demographic data available for this larger set of school districts since Census 2000. ACS data for approximately 900 school districts with population 65,000 or more are included in the annual ACS data releases. They enable assessment of more recent characteristics than provided by Census 2000. They enable assessment of how some demographic measures have changed since 2000. There are a few new types of measures that can provide different insights.
This document reviews access to and use of these demographic updates and use of the Proximity SDDynamics software and database to combine and analyze these and related data. Users of SDDynamics demographic updates should review the ACS data usage notes. See more about analyzing these data in the context of other geography and subject matter in the Texas Decision-Making Information Guide.
ACS Data Availability and Reliability
The population threshold of 20,000 is required as reliable estimates for smaller population areas cannot be developed from the ACS survey design. More attention to reliability of estimates is required as compared to sample based estimates from the decennial census. Some relative sense of the Margin of Error should be kept in mind while using these data.
ACS Data Access and Analysis
While these data are readily accessible using the Census Bureau FactFinder, they are quite difficult to use in an analytical manner. For example, there is no facility to "browse across" or sort school districts using a dataset/extract of these data. There is no facility to view these data as thematic maps to visually examine patterns. There is no facility to integrate other related data. This section reviews Proximity software and integrated data focused on accessing, viewing and analyzing these data. Applications shown here focused on Texas can be produced for any region using the same toolset.
ACS Subject Matter
The SDDynamics database includes ACS 05-07 subject matter tables listed below. Specific subject matter items are listed here: http://proximityone.com/txdmi/acs3yrtables.xls. Item names listed in the first column are also the dbase file names used in CommunityViewer for GIS analyses.
