Census of Population and Housing 1970, [San Diego, California]: Summary Statistic File 4A: Population

This data collection includes population data by census tract for San Diego County in 1970.

Separate tallies are available for the total, white, Negro, and Spanish American populations. Whites and Negros are defined as racial categories by the Census Bureau. In California, Spanish Americans include "Persons of Spanish language or Spanish surname". The California state 4A data file was processed with PERL and SPSS by the Social Science Data Collection (SSDC) staff of the University of California, San Diego from Census Bureau data processed by DUALabs, Inc. and archived at the Odum Institute. PERL script concatenated record type codes and output five data files that match the record types described in the codebook: total population, White population, Negro population, Spanish American population, and population allocations. These five f iles were subsequently processed with SPSS to extract tracts for San Diego County and compute additional population data content. Users may browse a list of data variables (tables and cells) included in these five data files. Data from Tables 1-99 are available for all files except allocations. Data from tables 100-127 are available for allocations and substitutions. The Census Bureau produced printed reports for 1970 Summary Tape File 4A. The UCSD Geisel Library maintains printed reports and census tract maps in 1970 Census of Population and Housing Census Tracts, San Diego, Calif. (SSH Docs US Stacks C 3.223/11:970/188).

本数据集包含1970年美国加利福尼亚州圣地亚哥县各普查街区（census tract）的人口数据。5%、15%与20%的样本计数源自《1970年人口与住房普查摘要磁带文件4A（Summary Tape File 4A）：人口卷》。人口统计特征涵盖年龄、职业、行业、收入及收入构成、婚姻状况、受教育年限、家庭类型、子女数量、贫困状况、出生地以及父母出身情况。数据集提供总人口、白人、黑人（Negro）以及西班牙裔人口的独立统计结果。其中白人与黑人由美国人口普查局（Census Bureau）界定为法定种族类别。在加利福尼亚州范围内，西班牙裔人口包含“使用西班牙语或拥有西班牙姓氏的人群”。加州版4A数据文件由加州大学圣地亚哥分校社会科学数据采集中心（Social Science Data Collection, SSDC）工作人员，基于DUALabs, Inc.处理并由奥达姆研究所（Odum Institute）归档的人口普查局原始数据，使用PERL与SPSS进行加工处理。PERL脚本用于拼接记录类型代码，并生成五个与代码手册中记录类型一一对应的数据集文件：总人口文件、白人人口文件、黑人人口文件、西班牙裔人口文件以及人口分配文件。随后工作人员使用SPSS对上述五个文件进行处理，提取圣地亚哥县的普查街区数据并补充计算额外的人口统计内容。用户可浏览这五个数据文件中包含的数据变量（含表格与单元格）清单。除人口分配文件外，其余所有文件均可获取1至99号表格的数据；人口分配与替换数据可获取100至127号表格的数据。美国人口普查局曾为1970年摘要磁带文件4A制作印刷版普查报告。加州大学圣地亚哥分校盖泽尔图书馆（UCSD Geisel Library）保存有《1970年人口与住房普查：圣地亚哥县普查街区》的印刷版报告及普查街区地图，馆藏编号为"SSH Docs US Stacks C 3.223/11:970/188"。
