Harmonize or Control? The Use of Multilevel Analysis to Analyze Trust in Institutions in the World

by Claire Durand, Isabelle Valois and Luis Patricio Peña Ibarra, Department of Sociology, University of Montreal

This article presents the current progress of a research project whose aim is to develop methods to analyze combined micro-data. The most recent papers that were presented (see references) give an insight into the work that has been accomplished to date.

This project was triggered by a preceding project where we aimed at analyzing change in support for Quebec sovereignty over time taking into account that question wordings and specific constitutional choices offered in survey questions varied over time and between surveys. We had identified close to 700 questions asked in polls over a 40-year period. In order to analyze these data, we used a multilevel model where polls were embedded within months. This allowed for analyzing the impact of question characteristics at level 1. Since time itself was at level 2, we could study change in support for sovereignty over time and the impact of events that occurred during each period controlling for question wording and constitutional choices (Yale & Durand, 2011).

This research ended with a frustration. We would have liked to be able to answer questions like whether the impact of age on support for sovereignty was fading over time. This requested combining micro-data, not just poll results. Therefore, we decided to combine data sets in order to be able to answer our research questions. However, instead of maintaining the focus on Quebec sovereignty, the focus was changed to institutional trust.

The first project is Valois’s Trust in Canada which involves combining survey data over a 40-year period; the second and third project started with the objective of combining all the surveys that had questions on trust in institutions everywhere in the world. One project is Durand et al.’s Trust in the World who combined the data from all the Barometers conducted outside Europe and the Latin American Public Opinion Project (LAPOP) surveys; the other one is Peña Ibarra’s Trust in Latin America, which uses a subset of these data to focus on Central and South America plus Mexico. The basic information on the three projects is presented in Table 1.

Harmonizing Corruption Items in Cross-national Surveys

by Ilona Wysmułek, Graduate School for Social Research, Polish Academy of Sciences

Corruption, given its secretive nature, is a phenomenon that is hard to capture in the interview situation.

In corruption research, surveys are among the major sources of our knowledge about the subject (Heath, Richards and de Graaf 2016; Karalashvili, Kraay and Murrell 2015).  However, there are several methodological challenges to studying cross-national trends in corruption with public opinion data. Corruption, given its secretive nature, is a phenomenon that is hard to capture in the interview situation. Some respondents are reluctant to answer sensitive questions and some may understand the concept differently than intended by researchers (Azfar and Murrell 2009; Bertrand and Mullainathan 2001). Moreover, international survey projects dealing with corruption continue to face challenges of unequal country representation. Estimation of rare event determinants also remains problematic, given that reported corruption instances are, for most modern democracies, highly infrequent.

To overcome some of these methodological problems, I apply ex-post harmonization of cross-national survey data in corruption research. In my dissertation project, I study corruption perception and individual corruption experience of giving informal payments (as a bribe or a gift) in public schools in Europe. I use cross-national survey data on corruption in public schools in Europe combined with country-level indicators, for example from the World Bank Education Statistics and OECD’s Education at a Glance. I follow the Survey Data Recycling (SDR) framework developed by the research team of Kazimierz M. Slomczynski, which provides a blueprint for ex-post survey data harmonization and for integrating surveys and other data sources (please see corruption project for more detailed information).

Harmonizing Ethnic Minority Status in International Survey Projects

by Olena Oleksiyenko, Graduate School for Social Research, Polish Academy of Sciences

This article focuses on issues of harmonizing information on ethnic minority status as part of a larger project on patterns of electoral and non-electoral political participation in post-soviet states. Specifically, I am interested in differences in political participation between a given country’s Russian-speaking minority and the majority population in Armenia, Azerbaijan, Belarus, Estonia, Georgia, Kazakhstan, Kyrgyzstan, Latvia, Lithuania, Moldova, Tajikistan, Uzbekistan and Ukraine.

There is no single international survey project that adequately covers all the former Soviet republics since the Soviet Union’s collapse, to current times. Even projects with the broadest country coverage, such as Life in Transition, do not allow for meaningful over-time comparisons. Hence, I selected, for purpose of ex-post harmonization, international projects that measure peoples’ electoral and non-electoral participation and ethnic identification in any of the post-soviet countries. Table 1 presents the list of the international survey projects I included, which taken together, span the period 1993- 2015.

Table 1. International Survey Projects with Relevant Data


Cross-national comparisons of ethnic groups are not as straightforward as it may seem, since in many cases the underlying concept of “minority group” is different in each state. The literature proposes different approaches to increase comparability of the concept. The “absolutist” approach suggests that only one marker of minority status should be taken into account, e.g. citizenship or language. The advantage of such a solution is conceptual clarity, but one can argue that the complexity of the minority status cannot be precisely studied with only one indicator. An alternative is the “relativist” approach to harmonization of items on minority status. This involves cross-classification of different ethnic referents to obtain a single, cross-nationally equivalent score on “ethnic minority status” (Lambert 2005). The problem with the “relativist” approach is the low availability of the same markers across all surveys.

New Book! Democratic Values and Protest Behavior: Harmonization of Data

The Harmonization Project has released their first book:

Democratic Values and Protest Behavior Harmonization of Data from International Survey Projects IFiS Publishers 2016

Democratic Values and Protest Behavior: Harmonization of Data from International Survey Projects by Kazimierz M. Słomczyński, Irina Tomescu-Dubrow, and J. Craig Jenkins with Marta Kołczyńska, Przemek Powałko, Ilona Wysmułek, Olena Oleksiyanko, Marcin W. Zieliński and Joshua K. Dubrow. 2016. Warsaw: IFiS Publishers.

This book is available on our website free to download and read.

Across the world, mass political protest has shaped the course of modern history. Building on decades of theory, we hypothesize that the extent and intensity of political protest is a function of micro-level democratic values and socio-demographics, country-level economic development and democratic practices, and the discrepancy (i.e. cross-level interaction) between a country’s democratic practices and peoples’ trust in key democratic institutions – that is, political parties, the justice system, and parliament.

This book is a Technical Report on the logic of, and methodology for, creating a multi-year multi-country database needed for comparative research on political protest. It concerns both the selection and ex-post harmonization of survey information and the manner in which the multilevel structured data can be used in substantive analyses.

The database we created contains information on more than two million people from 142 countries or territories, interviewed between the 1960s and 2013. It stores individual-level variables from 1,721 national surveys stemming from 22 well-known international survey projects, including the European Social Survey, the International Social Survey Programme, and the World Values Survey. We constructed comparable measures of peoples’ participation in demonstrations and signing petitions, their democratic values and socio-demographic characteristics. We complemented the harmonized individual-level data with macro-level measures of democracy, economic performance, and income inequality gathered from external sources. In the process, we pulled together three strands of survey methodology – on data quality, ex-post harmonization, and multilevel modeling.

This book is funded by the (Polish) National Science Center under a three-year international cooperation grant for the Institute of Philosophy and Sociology of the Polish Academy of Sciences (IFiS PAN), and The Ohio State University (OSU) Mershon Center for International Security Studies (grant number: Harmonia-2012/06/M/HS6/00322).
