TIGER/Line Shapefile, 2012, Series Information File for the Address Range-Feature County-based Shapefile
Description
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 provides
seamless national coverage with no overlaps or gaps between parts. Each TIGER/Line File is designed to stand alone as an independent data set, or it can
be combined with shapefiles for other counties to cover a region or 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 Files 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.
