RSEI Data Dictionary: Disaggregated Geographic Microdata for Other Geographies
The following tables provide descriptions for each field in each table. Note that for the Geographic Microdata, "Other Geographies" includes block groups, census tracts, and ZIP code files. For more information, see the RSEI methodology document and the RSEI Microdata documentation.
These files are the same as the disaggregated Geographic Microdata files, but instead of being presented at the grid cell level, the values are averaged over other geographies (block groups, census tracts or ZIP codes). Note that 3-year averaged files are no longer available; each files contains data for a single year only.
Naming: These files are named as follows, where XXXX is the reporting year for the data freeze, and YYYY is the year of the data contained in the file .
- Block group: censusmicroblockgroupXXX_YYYY.csv
- Census tract: censusmicrotractsXXX_YYYY.csv
- ZIP codes: censusmicrozipcodeXXX_YYYY.csv
Users should note that Geographic Microdata file structures and fields have changed for version 2.3.12. Documentation for previous versions can be found on the Geographic Microdata documentation web page.
