Dutch Parliamentary Election Study The Dutch Parliamentary Election Study is a longitudinal social science survey project that examines voter behavior, party competition, and public opinion in the Netherlands through systematic post-election interviews and panel data collection. The study links electoral outcomes, party dynamics, campaign effects, and demographic change across multiple national elections, providing evidence used by scholars at University of Amsterdam, University of Groningen, Erasmus University Rotterdam, and analysts at the Netherlands Institute for Social Research. Major users include researchers affiliated with Leiden University, Radboud University Nijmegen, Vrije Universiteit Amsterdam, and policy analysts at the Ministry of the Interior and Kingdom Relations.
The project collects data on voting intentions, turnout, party identification, candidate evaluations, and policy preferences tied to elections such as the Dutch general election, 2021, Dutch general election, 2017, Dutch general election, 2012, Dutch general election, 2006, and older contests like the Dutch general election, 1977 and Dutch general election, 1967. Survey waves commonly coincide with events including party congresses of Democrats 66, People's Party for Freedom and Democracy, Christian Democratic Appeal, and campaign milestones for figures like Mark Rutte and Geert Wilders. The dataset is frequently cited in comparative studies with projects such as the Comparative Study of Electoral Systems and the European Social Survey.
Origins trace to postwar electoral research traditions linked to institutions such as University of Amsterdam and institutes following models like the American National Election Studies and the British Election Study. Early waves documented transformations after formation of parties including Democrats 66 and the consolidation of the Christian Democratic Appeal; later waves captured fragmentation tied to entrants like Party for Freedom and regional movements in Friesland and Groningen (province). Collaborations expanded with centers at Centrum voor Beleidswetenschap and international partners including scholars from Oxford University, Harvard University, Sciences Po, and the Max Planck Institute for the Study of Societies.
Fieldwork employs mixed-mode surveys combining face-to-face, telephone, and web panels modeled on protocols used by the European Election Studies and the International Social Survey Programme. Sampling frames leverage population registries maintained by municipal authorities such as Gemeente Amsterdam and Gemeente Rotterdam, stratified by provinces including North Holland, South Holland, and North Brabant. Questionnaire modules adapt validated items used in studies by GESIS – Leibniz Institute for the Social Sciences and measures comparable to the World Values Survey. Analytical techniques incorporate logistic regression, multilevel modeling, and panel attrition corrections consistent with standards from American Political Science Review and methods taught at London School of Economics.
Major outputs include monographs and articles in journals like Acta Politica, European Journal of Political Research, Electoral Studies, and Party Politics. Findings document party system change, volatility illustrated in analyses of the Dutch general election, 2010 and the rise of populist actors exemplified by Geert Wilders's movements; studies address cleavage realignment related to migration debates after events such as the 2004 European Parliament election in the Netherlands and policy shifts following the Treaty of Lisbon. Notable authors include scholars affiliated with Tilburg University, Utrecht University, and research groups at the Netherlands Institute for Social Research.
Datasets and codebooks are distributed to researchers through archives modeled after the UK Data Service and the Data Archive of the Netherlands, with metadata standards similar to ICPSR. Sampling targets registered voters aged 18 and over, with oversamples for municipalities like The Hague and constituencies covering Utrecht (province). Panel retention strategies mirror protocols from the German Longitudinal Election Study, incorporating refreshment samples and weighting schemes to correct for nonresponse as practiced by the European Social Survey.
The study informs campaign strategy for parties such as Socialist Party (Netherlands), GreenLeft, and CDA while shaping parliamentary research at the Tweede Kamer der Staten-Generaal and policy briefs used by think tanks like Clingendael Institute and Netherlands Institute for Multiparty Democracy. It supports comparative inquiries linking the Dutch case to episodes like the European migrant crisis and electoral shifts studied in contexts such as France, Germany, Belgium, and Spain. Graduate curricula at University of Amsterdam and Leiden University integrate DPES findings into seminars on voting behavior and public opinion.
Critiques parallel those leveled at large-scale surveys including panel attrition noted in comparisons with the British Election Study, potential measurement error when aligning survey items with parliamentary roll-call behavior in the Tweede Kamer der Staten-Generaal, and debates over fieldwork timing relative to events like the 2008 financial crisis. Concerns also address underrepresentation of transient populations in port cities such as Rotterdam and limits on capturing intra-party factionalism within parties like Christian Democratic Appeal and People's Party for Freedom and Democracy.
