Census Tract Data, 1950: Elizabeth Mullen Bogue File

The 1950 Census Tract files were originally created by keypunching the data from the printed publications prepared by the Bureau of the Census. The work was done under the direction of Dr. Donald Bogue, whose wife, Elizabeth Mullen Bogue, completed much of the data work. Subsequently, the punchcards were converted to data files and transferred to the National Archive and Records Administration (NARA). ICPSR received copies of these files from NARA and converted the binary block-length records to ASCII format.

1950年人口普查区域文件最初由人口普查局编制的印刷出版物中的数据进行键盘穿孔制作。此项工作在唐纳德·博格博士的指导下完成，其妻伊丽莎白·穆伦·博格完成了大部分数据工作。随后，穿孔卡片被转换为数据文件，并转存至国家档案馆与记录管理局（NARA）。美国社会研究项目中心（ICPSR）从NARA获得了这些文件的副本，并将二进制的块长度记录转换为ASCII格式。
