title: Replication Data for: The Non-linearity of Populist Attitudes and Political Ideology

description: The relationship between populist attitudes and ideological orientations remains an area of considerable academic interest, yet much is still unknown about the ideological inclinations associated with populist attitudes. While many scholars acknowledge the link between populist attitudes and political ideology, existing studies often treat this relationship as either a given or a peripheral concern. This paper represents an initial exploration into the association between populist attitudes and political ideology. Utilizing data from the fifth wave (2016-2021) of the Comparative Study of Electoral Systems, which encompasses 43 countries and 52 elections, this study aims to uncover how this relationship manifests cross-nationally. By employing a variety of rigorous methodological models, including the Generalized Additive Model, our results reveal a non-linear relationship between populist attitudes and political ideology. Specifically, we find that political ideology and populist attitudes exhibit a U-shaped non-linear relationship and that ideological extremism and populist attitudes demonstrate an exponential non-linear relationship. These findings emphasize the nuanced interplay between ideological positions and populist attitudes, providing a deeper understanding of how they intersect.

title: ANES 1972 Time Series Study
title: Archival Version

description: This study is part of a time-series collection of national surveys fielded continuously since 1948. The election studies are designed to present data on Americans' social backgrounds, enduring political predispositions, social and political values, perceptions and evaluations of groups and candidates, opinions on questions of public policy, and participation in political life. In addition to the core content, this dataset also includes topics like women's liberation, racial attitudes, economic attitudes, payment of federal income tax, feelings about the quality of life, and various cultural attitudes. As a result of findings from previous ANES studies, the general themes of trust in government, alienation, and efficacy were emphasized in an attempt to determine the causes of the observed decrease in public support of the political system. Besides being a stand-alone time series study, this dataset also represents the first wave in a three-wave data collection that continued with the ANES 1974 Time Series Study (ICPSR 7355) and the 1976 ANES Time Series Study (ICPSR 7381). The full panel file of data from these years, the ANES 1972-1976 Merged File (ICPSR 7607), also includes some cases not represented in the time series studies. To maximize the number of questions asked in 1972, two forms of the interview were developed, and each was administered to half of the respondents in both the pre- and the post-election waves. Each half-sample of respondents assigned to a specific questionnaire version also constitutes a cross-national sample, representative of the study population, so that the two sub-samples may be used together, or separately for analysis purposes. The two forms contain approximately 80 percent of the same items, while 20 percent are unique questions. In addition, in the post-election wave, 57 Form I respondents were re-designated Form III, and 37 Form II respondents were re-designated Form IV, because they were interviewed using a mail questionnaire that contained most, but not all, of the questions included in the face-to-face versions of the post-election questionnaire. Demographic variables include sex, age, race and marital status, number of children in household, level of education, occupation and employment status, religious preference.

description: This study is part of a time-series collection of national surveys fielded continuously since 1952. The election studies are designed to present data on Americans' social backgrounds, enduring political predispositions, social and political values, perceptions and evaluations of groups and candidates, opinions on questions of public policy, and participation in political life. In addition to the usual content, other items included an evaluation of President Ronald Reagan's performance in office, his personal qualities, and the respondent's own feelings toward him.
description: Data for the 1982 National Election Study were obtained by interviewing, in person, individuals living in households in the coterminous United States, exclusive of households on military reservations. The 74 primary areas of the SRC national sample include 12 major metropolitan areas, 32 other standard metropolitan statistical areas (SMSAs), and 30 counties or county-groups representing the nonmetropolitan or rural portions of the country. At the overall rate of 1:35,360, a sample of 2,278 housing units was drawn. These are the dwellings where interviewers called in 1982 to attempt interviews with one objectively-selected eligible person. The selections were thinly spread, averaging only one or two from a sample block.

title: ANES 1984 Time Series Study
title: Archival Version

description: This study is part of a time-series collection of national
surveys fielded continuously since 1952. The election studies are
designed to present data on Americans' social backgrounds, enduring
political predispositions, social and political values, perceptions
and evaluations of groups and candidates, opinions on questions of
public policy, and participation in political life. Part 1 of this
collection contains the traditional Pre- and Post-Election Survey
(ICPSR Version). Interviews were conducted in person prior to the 1984
election. In the post-election wave, half of the respondents were
randomly assigned to be reinterviewed in person, and the other half to
be reinterviewed by telephone using a shortened version of the
questionnaire. In addition to the standard core questions, new topic
areas (most of which had been piloted in 1983) included measures of
"predispositions" such as economic individualism and egalitarianism,
and group identification items. Vote validation data also are
provided. Part 2, Continuous Monitoring: January 11, 1984, Through
December 31, 1984, was designed to examine the impact of the election
campaign on voters' perceptions, beliefs, and preferences.
Respondents were questioned about their knowledge of the candidates'
stands on the issues, about their own stand on the issues, and about
their opinions and evaluations of the candidates. Interviews were
conducted by telephone throughout the year, with a total of 46
separate cross-section samples selected by a random-digit dialing
design, and an average of 76 respondents interviewed in each of the 46
sample weeks. Although the survey instrument was very much the same
from one sample week to the next, some questions were deleted and
others added during the course of the campaign, as issues became more
or less relevant. Thirteen versions of the questionnaire were
incorporated into this data file. For each telephone number selected
in the Continuous Monitoring Study administrative information is
included, such as number of calls, household composition, and final
disposition.

description: This study is part of a time-series collection of national surveys fielded continuously since 1952. The election studies are designed to present data on Americans' social backgrounds, enduring political predispositions, social and political values, perceptions and evaluations of groups and candidates, opinions on questions of public policy, and participation in political life. In addition to the standard or core content items, new topics include evaluations of the presidential primary candidates, respondent's primary vote, the budget deficit, health insurance, foreign policy, equal rights for women, the drug problem, the Reagan presidency, recall of the 1984 presidential vote, parental party identification, evaluation of Bush and Dukakis on the issues of environment and crime, the death penalty, and new system support and political efficacy items. The file also contains post-election vote validation and election administration survey data as well as data collected in 1991 to revalidate the 1988 respondents in order to assess the reliability of the vote validation process.

description: face-to-face interviewTwo forms were used in both the pre- and post-election surveys so that a maximum amount of content could be included. For both the pre- and post-election surveys, half the sample was assigned to Form A, the other half to Form B. In particular, the lengthy section containing Reagan retrospective evaluation items was split between the two waves and the two forms in order not to make either the pre- or post-election instrument unacceptably long, and to study the effects of post-election media analysis of the presidency. The other major use of the two forms was to conduct an experiment in survey response.

Description: European regions were classified into three socioeconomic contexts (C1, C2, and C3) based on combined economic, demographic, and farmer-related variables at the NUTS 2 level. 

C1 or "High-profile" regions demonstrate positive characteristics like higher organic farming prevalence, younger and more trained farm managers, larger farms, lower unemployment, and a predominantly urban/intermediate character, suggesting a strong economic base for agroforestry. 

C3 or "Low-profile" regions face challenges such as lower organic farming adoption, fewer trained managers, an older farming population, lower economic output, higher unemployment, and a predominantly rural character, requiring targeted support. 

C2 or "Medium profile" regions encompass those not meeting C1 or C3 criteria (at least four of six socioeconomic factors), representing an intermediate category with unique attributes requiring a tailored approach to agroforestry implementation.
