Census of Population and Housing, 1980: Summary Tape File 3A, Puerto Rico

This data collection is a component of Summary Tape File 3, which consists of four sets of data containing detailed tabulations of the nation's population and housing characteristics produced from the 1980 Census. The STF 3 files contain sample data inflated to represent the total United States population. The files also contain 100-percent counts and unweighted sample counts of persons and housing units. All files in the STF 3 series are identical, containing 321 substantive data variables organized in the form of 150 "tables," as well as standard geographic identification variables. Population items tabulated for each person include demographic data and information on schooling, ethnicity, labor force status, and children, as well as details on occupation and income. Housing items include size and condition of the housing unit as well as information on value, age, water, sewage and heating, vehicles, and monthly owner costs. Each dataset provides different geographic coverage. STF 3A provides summaries for the states or state equivalents, counties or county equivalents, minor civil divisions (MCDs) or census county divisions (CCDs), places or place segments within MCD/CCDs and remainders of MCD/CCDs, census tracts or block numbering areas and block groups or, for areas that are not block numbered, enumeration districts, places, and congressional districts. There are 52 files, one for each state, the District of Columbia, and Puerto Rico. The information in the file for Puerto Rico is similar to but not identical to the data for the 50 states and the District of Columbia. Thus, this file is documented in a separate codebook. The Census Bureau's machine-readable data dictionary for STF 3 is also available through CENSUS OF POPULATION AND HOUSING, 1980 [UNITED STATES]: CENSUS SOFTWARE PACKAGE (CENSPAC) VERSION 3.2 WITH STF4 DATA DICTIONARIES (ICPSR 7789), the software package designed specifically by the Census Bureau for use with the 1980 Census data files.

本数据集为汇总磁带文件3（Summary Tape File 3，STF3）的组成部分，包含四组源自1980年美国人口普查的数据，涵盖全美人口与住房特征的详细制表结果。STF3文件包含经加权膨胀处理的抽样数据，用以精准代表全美总人口规模；同时还收录了人口与住房单元的百分百普查计数，以及未加权抽样计数。STF3系列的所有文件结构完全一致，均包含321个实质性数据变量，以150张“统计表格”的形式组织编排，同时附带标准地理识别变量。针对个人的统计人口项涵盖人口统计学数据、受教育程度、族裔、劳动力就业状况、子女相关信息，以及职业与收入的详细信息。住房相关统计项则包含住房单元的规模与状况，以及房产价值、房龄、供水设施、排污系统、供暖系统、车辆保有量与月度自有住房成本等信息。各数据集的地理覆盖范围各不相同。其中STF3A可提供以下层级区域的汇总统计数据：州或州等效区域、县或县等效区域、基层民政分区（Minor Civil Divisions，MCDs）或普查县分区（Census County Divisions，CCDs）、MCD/CCD范围内的社区或社区分段、MCD/CCD的剩余区域、普查地段或街区编号区域、街区组；对于未进行街区编号的区域，则涵盖枚举区、社区与国会选区。该数据集共包含52个文件，分别对应50个州、哥伦比亚特区以及波多黎各各一份。波多黎各对应文件的统计信息与50个州及哥伦比亚特区的数据类似，但并不完全一致，因此该文件配有独立的代码手册。美国人口普查局开发的1980年人口普查专用统计软件包CENSPAC（Census Software Package）3.2版（附带STF4数据字典，ICPSR编号7789），即《1980年美国人口与住房普查：附带STF4数据字典的CENSPAC 3.2版统计软件包（ICPSR 7789）》，也收录了STF3的机器可读数据字典。
