Abstract: In one aspect, a system and method is provided for developing small geographic area population, household, business and demographic count estimates and projections using a MAF. The systems and methods described herein use mailing addresses and corresponding address related records, in conjunction with the DPV validation and RDI coding functionality, as well as ZIP+4 type coding, in order to build a MAF with unique DPV validated addresses. Each address in the MAF is delivery point coded (DPC), mail delivery validated, has a residential/business address code, and has a USPS ZIP+4 type, FIPS code, latitude and longitude and selected demographic data. The MAF is then tabulated directly or used in conjunction with current county level or Census Bureau estimates to generate estimates of the census block records or census block group records and/or areas of any size or shape.
