The TIGER/Line shapefiles and related database files (.dbf) are an extract of selected geographic and cartographic information from the U.S. Census Bureau's Master Address File / Topologically Integrated Geographic Encoding and Referencing (MAF/TIGER) Database (MTDB). The MTDB represents a seamless national file with no overlaps or gaps between parts, however, each TIGER/Line shapefile is designed to stand alone as an independent data set, or they can be combined to cover the entire nation. The Address Ranges Feature Shapefile (ADDRFEAT.dbf) contains the geospatial edge geometry and attributes of all unsuppressed address ranges for a county or county equivalent area. The term "address range" refers to the collection of all possible structure numbers from the first structure number to the last structure number and all numbers of a specified parity in between along an edge side relative to the direction in which the edge is coded. Single-address address ranges have been suppressed to maintain the confidentiality of the addresses they describe. Multiple coincident address range feature edge records are represented in the shapefile if more than one left or right address ranges are associated to the edge. The ADDRFEAT shapefile contains a record for each address range to street name combination. Address range associated to more than one street name are also represented by multiple coincident address range feature edge records. Note that the ADDRFEAT shapefile includes all unsuppressed address ranges compared to the All Lines Shapefile (EDGES.shp) which only includes the most inclusive address range associated with each side of a street edge. The TIGER/Line shapefile contain potential address ranges, not individual addresses. The address ranges in the TIGER/Line Files are potential ranges that include the full range of possible structure numbers even though the actual structures may not exist.

The United States Environmental Protection Agency (USEPA) requires Michigan to attain the National Ambient Air Quality Standards (NAAQS) for six criteria pollutants. The data contained in this layer file outlines the statewide nonattainment areas and maintenance areas for the 2015 Ozone NAAQS as designated by the USEPA. The nonattainment areas consist of two partial counties (Allegan and Muskegon) and one full county (Berrien) located on the west side along Lake Michigan. In southeast Michigan there is a seven-county Attainment/Maintenance area. Further information about the six criteria pollutant NAAQS and Michigan’s ozone designation status can be found on EGLE Air Quality Division’s SIP and Attainment webpage.
