Description

STDMCD is a string variable indicating minor civil division.

STDMCD only exists in the 1940 1% sample. The original geographic strings that were entered for 1940 are often inconsistent and sometimes unclear as to which places they are specifying. Standardized geographic place names were created for consistency using an auxiliary dictionary of 1940 census geography compiled by the National Archives and Records Administration (NARA). NARA created this dictionary when they digitized original enumeration sheets from the 1940 census. The standardized geography string variables included in the 1940 file are: STDMCD, STDTRACT, STDWARD, STDED, STDCITY and STDCNTY. These standardized string variables also correspond to the published population reports from the 1940 census.

Another variable, MCDSTR, contains the original "as entered" alphabetic string for minor civil division. Most users will find STDMCD more useful because it contains strings that are uniform for each place.

This variable is only available in the 1940 1% file. STDMCD is a 90-character alphabetic string variable which reports the respondent's minor civil division of residence. MCDSTR contains the alphabetic string entries for minor civil division "as entered", however STDMCD differs since its alphabetic strings have been cleaned and standardized for consistency using an auxiliary dictionary of 1940 census geography compiled by the National Archives and Records Administration (NARA). NARA created this dictionary when they digitized original enumeration sheets from the 1940 census. STDMCD 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).
