Data & Tools Download

Complete SVI documentation is available for each year under the Data banner, Download Type.
The SVI geospatial data formats have evolved over the years from Esri’s geodatabase format (.mdb) for 2000 and 2010, to Esri’s shapefile format (.shp) for more recent years. Databases are also available in .csv text format. The range of file formats means the data can be used in ArcGIS 10.0 or higher, QGIS (free and open source), Microsoft Access and Excel, as well as other commonly used software packages.

American Community Survey Toolbox

Users of ACS data, or any other sample data, cannot ignore the error if they want valid analysis results. In response to these concerns, we developed a geoprocessing toolbox for ArcGIS that enables users to more easily calculate statistical measures of error. The ACS toolbox:
  1. calculates margins of error for user-derived data;
  2. calculates coefficient of variation (CV), a measure of relative error for comparing error across a study area;
  3. determines, using Census specifications, statistically significant difference among enumeration units over space and time; and
  4. helps the user determine a suitable classification scheme considering data uncertainty.

Population Estimator

The Population Estimator is an ArcGIS geoprocessing tool that estimates the population in a user-defined area surrounding a specified feature or features of interest.
