Design: This study contained a two-wave investigation of the 1971 election for the Second Chamber of Parliament in the Netherlands in the Netherlands. The first wave was held during the election campaign, which means two months before the election date. The second wave was held after the election date of April 28, 1971. The election study explores accurately the respondents’ political orientation. The questions in the pre-election interview focused on the respondents’ partisan preferences, political participation and attitudes toward political issues. In the post-election phase the respondents were questioned about their satisfaction with both the election results and the election procedure. The panel study consisted of six waves. The first two waves were held in 1971, the third was held after the elections from November 29, 1972, the fourth was held after the formation of the Den Uyl-cabinet on May 31, 1973. The fifth wave was held following the pre-1977 election. The final wave was conducted in 1979.
Fieldwork dates: The fieldwork (mainstudy) was done from March 1971 till May 1971. The election date was April 28, 1971. The fieldwork of the panel study was done from March 1971 till 1979.
Sampling frame: This study consisted of a two stages (stratified random) sampling procedure. At first municipalities were selected. In order to get a representative selection of municipalities, information which described the municipalities was obtained from the Central Bureau for Statistics (CBS). 396 municipalities were included in the sample, three municipalities did not cooperate. In the second stage registered voters within these municipalities were selected. In all 396 municipalities addresses were randomly selected. In 143 of the municipalities the addresses were drawn from personal or voters’ registers. In two municipalities addresses could only been drawn from dwelling registers. The other 251 municipalities had an automated administration from which the addresses were drawn.In the first wave there was a selection of 3.330 persons. 2.495 persons did the interview. In the second wave 1.980 respondents were reinterviewed. The panel study was based on the sample drawn for the election study in 1971.
Response (main study): In the first wave there was a response of 75 percent, which means that 2495 pre-election interviews successful were completed. In the second wave the response was 79 percent of the first wave. This resulted in a 20 percent panel attrition.
Panel study: This election study did include a panel study. This study consisted, as already mentioned, of six waves. The study period of this panel study began in 1971 and ended in 1979. The principal investigators of this study were C. van der Eijk and B. Niemoeller (both University of Amsterdam, the Netherlands).
