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.
