NUMPERHH
Number of persons in household

Description

NUMPERHH reports how many persons lived within the household. This number is sometimes larger than NUMPREC (the number of person records following the household record in the IPUMS), because the census PUMS from 1850 to 1930 did not sample large households (i.e., households containing more than 30 persons) in their entirety. Instead, individuals (SAMPRULE=4) or related groups (SAMPRULE=3) were sampled from these large households; in these cases, NUMPERHH will show how big the entire household was. See SAMPRULE and "Sample Designs" for a discussion of differences in how the samples were drawn.

User note: Because of data entry errors in a small number of large and complex households, NUMPERHH was occasionally entered as less than NUMPREC--a logical impossibility. Correcting these data would be prohibitively difficult, and NUMPERHH has been coded as missing (9999) for these cases. However, visual inspection of these households suggests that DWSIZE is a reasonable approximation of true NUMPERHH values where stated NUMPERHH values are illogical.

Additionally, there are a small number of household records not sampled from within a larger household where NUMPERHH is larger than NUMPREC; these are likely due to data entry errors.

Codes

NUMPERHH is a 4-digit numeric variable which reports how many persons lived within the household. This number is sometimes larger than NUMPREC (the number of person records following the household record in the IPUMS), because the census PUMS from 1850 to 1930 did not sample large households (i.e., households containing more than 30 persons) in their entirety. Instead, individuals (SAMPRULE=4) or related groups (SAMPRULE=3) were sampled from these large households. In these cases, NUMPERHH will show how big the entire household was. See SAMPRULE and "Sample Designs" for a discussion of differences in how the samples were drawn. NUMPERHH 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 by Census year (and data sample if specified).

NUMPERHH Specific Variable Codes
0000 = Vacant but habitable dwelling (1860 and 1870)
0099 = 99 Persons (Top Code: 1910 1.4% sample)*
9999 = Missing/blank

*This Top code exists only for cases from the Preston sample which can be identified as SAMP1910 = 5

Comparability
