Low & Moderate Income Area Analysis

GIS tools and data resources enable easier and more comprehensive mapping, geospatial and demographic analysis of census tract geography to examine low and moderate income (LMI) area pattern and characteristics.  Resources are reviewed in this section to analyze LMI data by census tract.  Though focused on LMI applications, the resources may be applied to a much broader set of census tract mapping and demographic-economic pattern analysis.

Low and moderate income designation is closely associated with implementation of the Home Mortgage Disclosure Act (HMDA) and the Community Reinvestment Act (CRA) and is widely used in many other applications as a measure of economic prosperity. The HUD Community Development Block Grant (CDBG) program seeks to expand economic opportunities for LMI areas. Of the 72,581 Census 2010 census tracts (U.S. and Puerto Rico), 5,588 are designated low income and 15,998 are designated as moderate income based on 2013 HMDA designations.

Use tools described in detail at http://proximityone.com/tractslmi.htm to analyze LMI areas of interest. Optionally set your own designations of LMI.

The following view shows a thematic pattern map of census tracts by low and moderate income status in the Houston, Texas area (red: low; orange: moderate). In this section we will review how, in just a few steps, you can develop maps like this one for your areas of interest, and others with further drill-down and labeling, using ProximtyOne no-fee resources. These resources enable national scale applications and include all Census 2010 census tracts.

We have integrated HMDA “Census 2013” data with American Community Survey demographic-economic data into a U.S. national scope shapefile. It has been made a part of a ready-to-use GIS project. See details and additional details.
