In this section, you will learn to examine low and moderate income characteristics (based on median family income) by census tract using iVDA with the "Base" project.  The Federal Financial Institutions Examination Council (FFIEC) assigns measures of low and moderate income to census tracts. These data are used for financial institution compliance and related analyses regarding the Home Mortgage Disclosure Act (HMDA) and the Community Reinvestment Act (CRA). VDAGIS resources enable stakeholders to examine these data geospatially and in context of other geography.  See related information and interactive table.

 

iVDA is one part of a broader VDA GIS resource framework.  See more about VDA GIS.
