Abstract
The census of manufactures enforced in the U. S. has come through three major transitions in its history since 1810. (1) The conceputual changes in “establishment”; (2) The changes in enumuration coverage; and (3) The conceptual changes in “industry” and changes in the principle of “industrial classification.” In (1), it is examined how the idea of “establishment” has separated from the concept of the “enterprise”; and in (2), how the enumuration coverages has been changed under what sort of view point of census of manufactures; then finally in (3), under what kind of condition, the branches of manufacturing have been classified as “industries” and how the standard of “industrial classification” has changed.
