Research on Public Attitudes to Migration: What, Where and by Who?

We present a series of visualizations of a dataset of articles about public opinion towards migration, which underlies the meta-analysis authored by Dražanová, Gonnot, Heidland & Krüger (2021).

We analysed hundreds of scientific articles to understand more about this important and growing field of research. Our sample of consists of 529 articles. To construct it, we first settled on five base disciplines – Migration and Ethnic Studies, Economics, Political Science, Psychology, and Sociology. Using the journal-rankings provided by Clarivate (JIF), SCImago (SJR), and Google Scholar, we picked the top 30 journals from each discipline. The selection was then refined to articles with a specific focus on attitudes towards migration. Information was gathered into an accessible resource that allows users to dig into the details of scientific work on attitudes to migration. Our analysis allows us not only to see the topics for research, but also more general questions about the composition and production of the social science scholarship on attitudes to migration. We provide insights in terms of method, research question, and sample, as well as the characteristics of the authors such as where they are based and their gender.

Historical Index of Ethnic Fractionalization Dataset (HIEF), Version 2.0

The Historical Index of Ethnic Fractionalization (HIEF) dataset contains an ethnic fractionalization index for 162 countries across all continents. The dataset covers annually the period 1945-2013. The ethnic fractionalization index corresponds to the probability that two randomly drawn individuals within a country are not from the same ethnic group. The new dataset is a natural extension of previous ethnic fractionalization indices and it allows its users to compare developments in ethnic fractionalization over time, as described in this blog post. The figure below shows the development of ethnic fractionalization (1945 – 2013) in a sample of European countries.
