ESRP SURVEYS

AUSTRIA

Fielded: September 30 to October 10, 2017

Interviews: 990

Fielded by: YouGov

Description: 1072 respondents were interviewed and then matched down to a sample of 990 to produce the final dataset (815 general population and a 175 oversample of Austrians highest on the base Populism Propensity Score (PPS) comprised of four child rearing questions). The four child rearing questions have been used on social science surveys in the United States to rank respondents’ disposition to authoritarianism.

Respondents were matched to a sampling frame on gender, age, education, past vote, and federal state. The frame was constructed by stratified sampling from the full 2013 Austrian Election Study (AUSNES) sample with selection within strate by weighted sampling with replacements (using the person weights on the public use file).

The matched cases were weighted to the sampling frame using iterative proportional fitting (IPF). The matched cases were weighted to six categories -- age by gender, three categories -- education, federal state, and official turnout and voting results of the 2017 Austrian federal election.

The final dataset was subset on authoritarian respondents, and the oversample was adjusted to match the distributions of age by gender categories, education categories, and official turnout and voting results of the 2017 Austrian federal election of those respondents.

FRANCE

Fielded:  April 13, 2017 to April 20, 2017

Interviews: 1432

Fielded by: YouGov

 

GERMANY

Fielded:  July 27, 2017 to July 31, 2017

Interviews: 1352

Fielded by: YouGov

Description: 949 German adults plus an oversample of 403 Germans highest on the base Populism Propensity Score (PPS) comprised of four child rearing questions – an additional 1405 German adults were screened to produce the oversample. The four child rearing questions have been used on social science surveys in the United States to rank respondents’ disposition to authoritarianism.

The general population sample was weighted to YouGov benchmarks on region, past vote, and ideology, as well as gender and age based on population data from the 2015 Eurobarometer.

The survey starts for the oversample of 1405 German adults was also weighted to general population benchmarks for region, gender, and age. The sample was then subset on the 403 authoritarians, and weights post-stratified to the observed distribution of prior vote in the PPS portion of the general population sample to produce the oversample weight.

THE NETHERLANDS

Fielded:  March 21, 2017 to March 29, 2017

Interviews: 1300

Fielded by: YouGov

Description: 2058 respondents were interviewed and matched down to a sample of 900 Dutch adults (18+) and another sample of 1000 Dutch adults containing 400 adults. These adults scored highest on the base Populism Propensity Score (PPS) comprised of four child rearing questions. The four child rearing questions have been used on social science surveys in the United States to rank respondents’ disposition to authoritarianism.

Both samples were weighted to the sampling frame using propensity scores. The matched cases and the frame were combined and a logistic regression was estimated for inclusion in the frame. The propensity score function included age, gender, and level of education. The propensity scores were grouped into deciles of the estimated propensity score in the frame and post-stratified according to the deciles. The weights for the general population sample were then post-stratified on the 2017 general election vote. The PPS oversample was then post-stratified to the observed 2017 general election vote distribution of the PPS subset of the general population sample.
