DutchPolitics: Political party and candidate preference in the Netherlands

Description Usage Format Source References Examples

Description

The data come from a Dutch panel study (T1 = February 1977, T2 = March 1977) and concern the questions for which party the respondent intends to vote (variables A and B, respectively) and which candidate the respondent prefers to become the next Prime Minister (C and D). The data have been analyzed before (Hagenaars, 1986, 1988, 1990), and more information on the panel study and the outcomes may be obtained from these references.

The data are tabulated in Bergsma, Croon, and Hagenaars (2009, Table 6.1).
