This article is a preliminary report of a joint survery conducted in 1952 by seven investigators including the authors.
The questionnaire used consisted of six sections, e.g. : (a) items relating to the authoritarian personality, (b) politico-economic orientation, (c) class identification, (d) social grading of occupation, (e) spatial mobility, (f) face-sheet.
The population from which the sample for this survey was drawn is the adult male population of approximately 2, 500, 000 individuals living in the urban districts of the Tokyo metropolis.
Considerations which entered into the decision concerning sample size were : (a) the precision of the estimate, (b) the precision of the test of significance, and (c) the limitation of the time and financial resources. The size thus determined wes 700.
Stratified sub-sampling and double sampling were used. The population was divided into 70 strata according to the type of industry and social characteristics of each districts. One primary sampling unit (cho or chôme-street) from each stratum was selected by probability-proportionately and from there 70 primary sampling units 40 male adults in proportion to the size of each stratum were obtained. These adults were again stratified according to age, occupation, and the characteristics of their dwelling place, and the final sample of 700 was obtained at a sampling ratio of 4.5 Population from which the sample was drawn was inferred from the registry of family cards.
Fieldwork was conducted through the use of the house-to-house interview method and 534 person's in the sample (%) were interviewed. In order to estimate the effect of failure to interview a portion of the sample, the age-and occupation-composition of the non-interviewed group was examined and the “quasi-re-survey” method was utilized. This examination shows that deviation due to non-interviewing of a portion of the sample was negligible.
The theoretical framework and the results of this survey will be reported in the following issues by individual invertigators.
