Description
In 1960, all persons included in the IPUMS answered the same population questions, but some of the housing questions were asked of only a subset of households in the IPUMS. SAMP1960 reports which set of housing questions the household members answered.
One dimension of SAMP1960 indicates whether the household received the PH4 census form, distributed in cities of 50,000+ inhabitants, or the PH3 form, distributed elsewhere. Only households in large cities were asked about the presence of elevators (see ELEVATOR) and the number of stories in the structure containing their housing unit (see STORIES). Only households outside large cities were asked about farm-related topics, such as land acreage of 10+ acres (see ACREPROP), land rented for farming (see LANDRENT), and gross receipts from the sale of farm products (see FARMPROD). Questions about sewage facilities (see SEWAGE) and the source of water supplies (see WATERSRC) were also only asked outside large cities.
All cases included in the IPUMS for 1960 are drawn from the 25 percent of households that received the long-form questionnaire. Of these long-form households, four-fifths (or 20 percent of all households) received one additional set of housing questions, while the other fifth of long-form households received different additional housing questions. The second dimension of SAMP1960 reports whether a given household was in the 20 percent or the 5 percent subsample for these additional housing questions. Thus, for example, a household coded as 1 in SAMP1960 has a label of "20% form, PH3 sample." This indicates the household received the form distributed outside large cities and the additional housing questions given to 20 percent of all households (and to 80 percent of the long-form households).
