Description

IND1930 reports the industry in which the person worked, coded into the original 1930 census classification scheme. In census usage, "industry" refers to work setting and economic sector, as opposed to the worker's specific technical function, or "occupation."

Some persons work in more than one industry. The 1930 census instructions asked for the industry from which the person earned the most money. Respondents not sure about this were to report the industry in which they spent the most time. For persons listing more than one industry, the samples use the first one listed. Persons not currently employed were to give their most recent industry.

The variable IND provides a numeric industrial classification that is identical to the IND1930 scheme. The correspondence between the IND and IND1930 codes is recorded in the 1930 Industry Codes list.

IND1930 is a 4-digit alphanumeric variable which reports the industry in which the person worked, coded into the original 1930 census classification scheme. In census usage, "industry" refers to work setting and economic sector, as opposed to the worker's specific technical function, or "occupation". IND1930 specific variable codes for missing, edited, or unidentified observations, observations not applicable (N/A), observations not in universe (NIU), top and bottom value coding, etc. are provided below if applicable by Census year (and data sample if specified).

Comparability

To increase comparability over time, the IPUMS provides IND1950, which applies a common classification system over time. This variable is created in the same way as the parallel occupational variables, which are discussed at length in "Occupation Codes and Income Scores."

User caution: IND1930 contains alphabetic characters. See IND for a fully numeric classification of occupations.

The term "labor force" and other key employment terms are defined in the documentation for EMPSTAT.
