This data collection contains FIPS codes for state, county, county subdivision, and place, along with the 1990 Census tract number for each side of the street for the urban cores of 550 counties in the United States. Street names, including prefix and/or suffix direction (north, southeast, etc.) and street type (avenue, lane, etc.) are provided, as well as the address range for that portion of the street located within a particular Census tract and the corresponding Census tract number. The FIPS county subdivision and place codes can be used to determine the correct Census tract number when streets with identical names and ranges exist in different parts of the same county. Contiguous block segments that have consecutive address ranges along a street and that have the same geographic codes (state, county, Census tract, county subdivision, and place) have been collapsed together and are represented by a single record with a single address range.

本数据集收录了美国550个县城市核心区内各街道两侧的州、县、县分区、建制地的联邦信息处理标准（FIPS）代码，以及1990年人口普查区（Census tract）编号。数据集同时提供街道名称信息，包括前缀和/或后缀方位词（如北、东南等）与街道类型（如大道、车道等），还包含该街道段在对应人口普查区内的地址范围与匹配的人口普查区编号。当同一县内不同区域存在名称与地址范围完全一致的街道时，可借助FIPS县分区与建制地代码确定正确的人口普查区编号。针对同一条街道上地址范围连续、且拥有相同地理代码（州、县、人口普查区、县分区、建制地）的连续街区段，已将其合并聚合，并以单条记录及单一地址范围进行呈现。
