Description/Comparability: 
In 1960 all respondents answered the same population questions, but some of the housing questions were asked of a smaller sample of the population. SAMP1960 identifies which set of questions the household answered. All households in the 1960 census were included in either the PH4 sample, those people in cities with 50,000 or more residents, or the PH3 sample, those people living outside large cities. The PH4 included questions about elevators and stories, while the PH3 collected information about sewage disposal and water source. In 1960, 25% of the households also received a second questionnaire containing additional "sample" questions; the PUMS is selected entirely from those households responding to these supplementary questions. From these households, four out of five were sent one questionnaire (the 20% form) and one out of five were sent another questionnaire (the 5% form). The 1960 PUMS maintains the same proportion of households; 80% responded to the 20% form, and 20% responded to the 5% form. 

The following household variables are available only for the indicated samples: 

See Chapter 1, "Introduction," and Chapter 2, "Sample Designs," for more information about the 1960 sampling procedure. 

SAMP1960 is only available in 1960.
