UNI-CEN Standardized Census Data Table - Census Tract (CT) - 1971 - Long Format (DTA) (Version 2023-03)
收藏资源简介：
UNI-CEN Standardized Census Data Tables contain Census data that have been reformatted into a common table format with standardized variable names and codes. The data are provided in two tabular formats for different use cases. "Long" tables are suitable for use in statistical environments, while "wide" tables are commonly used in GIS environments. The long tables are provided in Stata Binary (dta) format, which is readable by all statistics software. The wide tables are provided in comma-separated values (csv) and dBase 3 (dbf) formats with codebooks. The wide tables are easily joined to the UNI-CEN Digital Boundary Files. For the csv files, a .csvt file is provided to ensure that column data formats are correctly formatted when importing into QGIS. A schema.ini file does the same when importing into ArcGIS environments. As the DBF file format supports a maximum of 250 columns, tables with a larger number of variables are divided into multiple DBF files. For more information about file sources, the methods used to create them, and how to use them, consult the documentation at https://borealisdata.ca/dataverse/unicen_docs.

UNI-CEN标准化普查数据表（UNI-CEN Standardized Census Data Tables）收录经重新格式化的普查数据，所有数据均采用通用表格结构，搭配标准化的变量名称与编码。该数据集针对不同应用场景提供两类表格格式：“长格式”表格适配统计分析环境，“宽格式”表格则多用于地理信息系统（Geographic Information System，GIS）环境。长格式表格以Stata二进制（dta）格式存储，可被所有统计软件读取。宽格式表格附带代码本，以逗号分隔值（comma-separated values，CSV）与dBase 3（dbf）格式提供。宽格式表格可便捷地与UNI-CEN数字边界文件进行关联拼接。针对CSV文件，配套提供.csvt文件，以确保其导入QGIS时列数据格式准确无误；若导入ArcGIS环境，则可通过schema.ini文件实现相同功能。由于DBF文件格式最多支持250列，当变量数量超出该阈值时，数据表将被拆分为多个DBF文件。如需了解文件来源、制作方法及使用方式等更多细节，请参阅https://borealisdata.ca/dataverse/unicen_docs 处的官方文档；若想了解该项目的详细信息，可访问https://observatory.uwo.ca/unicen。
