Summary This is a public opinion poll on the 1996 General Election for the House of Representatives, which was conducted before and after the election. As a US-Japan joint project, the poll deals with the first general election after the House went through institutional changes, and its items are composed in a way conductive to verify two models concerning institutional impacts (i.e. the political culture model and the psychological model expecting manifestation of institutional realities). Through the examination of impacts of political culture and social psychological effects of institutional changes in the Japanese political process, the survey offers opportunities to study Japanese adaptation and maladaptation to the political system and party reorganization processes as understood by voters. In addition, data provided by the poll include those items which correspond to an international project of the CSES (Comparative Study of Electoral Systems), thereby offering comparative data involving 52 nations in the world.
JEDS96 is a shortened name of Japanese Elections and Democracy Study 96. Data sets written in English (jeds96e1.sav) is available. The number following jeds96.. means the version, and the contents are in agreement if the number of the Japanese version and the English version is the same.

Sampling Procedure Probability: Systematic random
Probability: Stratified
Probability: Stratified: Proportional
Probability: Multistage
Stratified two-stage random sampling. (Details are given below.)
1. Population: Nation's men and women, 20 years old and above.
2. Number of individuals sampled: 2,100
3. Number of localities sampled: a total of 154 localities (121 cities and wards, and 33 towns and villages).
4. Sampling methods: stratified two-stage random sampling
(1) The nation's cities, towns, and villages were divided into 11 regional blocks on the basis of proportional representation districts.
(2) The localities in each regional block were further divided into 5 groups, depending on their population size. This generated a total of 52 first-stage strata The 5 criteria for population size were derived from the "Numerical Tables of Nationwide Populations, Households, and Population Trends" (edited by the Local Administration Bureau of the Ministry of Home Affairs), which were in turn derived from the Residents' Basic Registrar as of March 31, 1996.
(3) A total of 2,100 slots were distributed to the 52 strata in proportion to their estimated numbers of people 20 years of age or above (as of March 31, 1995) so that each survey spot would have 10 to 16 slots. This generated a total of 154 survey spots.

(1) The Survey Districts set upon the National Census of 1990 were used to derive the survey spots as the unit of first-stage sampling.
(2) In the sampling of survey spots (districts), a regular interval method was used for those strata which received two or more survey spots. The interval for each stratum was determined by dividing its total number of survey districts by the number of allocated survey spots.
(3) The order of cities, wards, towns, and villages for each stratum was derived from the localities' codes used in the above National Census.
(4) Individuals on each survey spot were sampled at a regular interval from the Voters' List (or the Residents' Basic Registrar in some cases) within the spot's sphere (towns, chome, banchi, districts, etc. were designated).
Mode of Data Collection Interviewing (except the supplementary survey in which postcards were mailed out)
