Census Establishment Size Distribution Data, 1963, 1967, 1972 (M279)

There are two datasets for 1963. They are similar in arrangement as the 1967 and 1972 files, described below. One is aggregated and on is dis-aggregated. In this dataset, a technique for dis-aggregating the data allows for estimates of the true values of the aggregated variables. Each record is uniquely associated with a particular size class in a particular industry. Records are sorted by 1) Census SIC, and 2) Size class code. There are two datasets for 1967. The first dataset contains census statistics by establishment size classes for the 2- and 4-digit census manufacturing industries. Data is also included for \"all industries\" under the 1-digit code \"1\". The data is often aggregated to avoid revealing confidential firm information. Each record is uniquely associated with a particular size class in a particular industry. Records are sorted according to 1) Census SIC and 2) Size class code. The sort is in ascending sequence. The number of records per industry is variable because empty size classes are not given. The source of this file is from U.S. Bureau of the Census. Census of Manufactures: 1967 Subject Statistics: Size of Establishments. The second 1967 dataset (dis-aggregated data) contains the 1967 census statistics by establishment employment size classes for the 2- and 4-digit census manufacturing industries, but differs from the original data in one important respect. In the original data (see above) is aggregated to preserve confidentiality of firm information. In this dataset, a technique for dis-aggregating the data allows for estimates of the true values of the aggregated variables. Each record is uniquely associated with a particular size class in a particular industry. Records are sorted by 1) Census SIC, and 2) Size class code. For each industry there are eleven records; one for each of the 10 size classes, plus an additional record for industry totals. The source of the data is from the U.S. Bureau of the Census. Census of Manufactures: 1967. Subject Statistics: Size of Establishments. As with the1967 data, there is one aggregated file and one dis-aggregated file for the 1972 datasets. The first 1972 dataset contains census statistics by establishment employment size classes for the 2- and 4-digit census manufacturing industries. Data is also included for \"all industries\" under the 1-digit code for \"0\". The data is aggregated to preserve confidentiality of firm information. Each record is uniquely associated with a particular size class in a particular industry. Records are sorted according to 1) Census SIC and 2) Size class code. For each industry there are 12 records; one for each of ten size classes, on record for establishments covered by administrative records, and one record for industry totals. The source of the data is from U.S. Bureau of the Census. Census of Manufactures: Vol. 1, parts 1 and 2, 1972. The second 1972 file is similar to the 1967 dis-aggregated file. This file contains the 1967 census statistics by establishment employment size classes for the 2- and 4-digit census manufacturing industries, but differs from the original data in one important respect. In the original data (see above) is aggregated to preserve confidentiality of firm information. In this dataset, a technique for dis-aggregating the data allows for estimates of the true values of the aggregated variables. Each record is uniquely associated with a particular size class in a particular industry. Records are sorted by 1) Census SIC, and 2) Size class code. For each industry there are eleven records; one for each of the 10 size classes, plus an additional record for industry totals. The source of the data is from the U.S. Bureau of the Census. Census of Manufactures: Vol. 1, parts 1 and 2, 1972.1963年共有两份数据集，其编排格式与下述1967年及1972年数据集一致。其中一份为聚合式数据集（aggregated dataset），另一份为拆解式数据集（disaggregated dataset）。本数据集采用数据拆解技术，可估算聚合变量的真实取值。每条记录唯一对应特定行业内的特定规模层级。记录排序依据为：1）普查标准产业分类（Census SIC）；2）规模层级代码。 1967年同样设有两份数据集。第一份数据集包含按企业规模层级划分的2位与4位码普查制造业行业统计数据，同时涵盖以1位码"1"标识的"全行业"统计数据。为避免泄露企业机密信息，该数据多采用聚合形式存储。每条记录唯一对应特定行业内的特定规模层级。记录排序依据为：1）普查标准产业分类；2）规模层级代码，且采用升序排列。各行业的记录数量并不固定，空规模层级不会被纳入数据集。本数据集源自美国人口普查局（U.S. Bureau of the Census），对应资料为《1967年制造业普查：主题统计：企业规模》。 第二份1967年数据集（拆解式数据）包含按企业雇佣规模层级划分的2位与4位码普查制造业行业1967年统计数据，但与原始数据存在一处关键差异。原始数据（见前文）为保密企业信息而采用聚合形式存储。本数据集通过数据拆解技术，可估算聚合变量的真实取值。每条记录唯一对应特定行业内的特定规模层级。记录排序依据为：1）普查标准产业分类；2）规模层级代码。每个行业对应11条记录：10个规模层级各对应1条记录，外加1条行业总计记录。本数据集源自美国人口普查局，对应资料为《1967年制造业普查：主题统计：企业规模》。 与1967年数据集一致，1972年数据集同样包含一份聚合式文件与一份拆解式文件。 第一份1972年数据集包含按企业雇佣规模层级划分的2位与4位码普查制造业行业统计数据，同时涵盖以1位码"0"标识的"全行业"统计数据。为保密企业信息，该数据采用聚合形式存储。每条记录唯一对应特定行业内的特定规模层级。记录排序依据为：1）普查标准产业分类；2）规模层级代码。每个行业对应12条记录：10个规模层级各对应1条记录、1条对应行政记录覆盖企业的记录，外加1条行业总计记录。本数据集源自美国人口普查局，对应资料为《1972年制造业普查：第1卷，第1、2部分》。 第二份1972年数据集与1967年拆解式数据集结构相似。该数据集包含按企业雇佣规模层级划分的2位与4位码普查制造业行业1967年统计数据，但与原始数据存在一处关键差异。原始数据（见前文）为保密企业信息而采用聚合形式存储。本数据集通过数据拆解技术，可估算聚合变量的真实取值。每条记录唯一对应特定行业内的特定规模层级。记录排序依据为：1）普查标准产业分类；2）规模层级代码。每个行业对应11条记录：10个规模层级各对应1条记录，外加1条行业总计记录。本数据集源自美国人口普查局，对应资料为《1972年制造业普查：第1卷，第1、2部分》。
