We look at the politicisation of immigration in Switzerland during the oil crisis of the 1970s and the financial crisis of the late 2000s. Based on 2,853 newspaper claims from 1970-1976 and 1995-2018, we measure and compare differences in salience, polarisation, actor diversity and frame use between crisis and non-crisis periods. We find that immigration was indeed more salient, polarised, and diversified during the oil crisis, but the situation is less clear for the financial crisis. There was increase in the use of identity-related frames for both periods. Crises do not increase politicisation automatically but may provide important opportunity structures that foster it.

PLOS ONE. 16(3): e0248066.  [ Open Access | Data: Mobility and border control | Data: International travel restrictions ]

A research note to introduce the Citizenship, Migration and Mobility in a Pandemic (CMMP). This new dataset features systematic information on border closures and domestic lockdowns in response to the Covid-19 outbreak in 211 countries and territories worldwide. We document the evolution of the types and scope of international travel bans and exceptions to them, as well as internal measures including limitations of non-essential movement and curfews in 27 countries.

Estimates different kinds of contemporary migration trajectories, highlighting multiple or repeated migrations. Using sequence analysis on linked longitudinal register data, we identify different migration trajectories for three cohorts (1998, 2003, and 2008) of 315,000 immigrants in Switzerland. We demonstrate high heterogeneity in migration practices, showing that direct and definitive settlement in the destination country remains a common trajectory and that highly mobile immigrants are less common.

Ruedin, Didier. 2021. ‘Decision-Making Under Uncertainty: African Migrants in the Spotlight’. Social Inclusion 9 (1): 182–186. [ Open Access | Editorial ]
Examines questions of decision-making under limited (and contradictory) information, focusing on migration decisions. Migrants are far from a homogenous population, but they commonly use narratives as heuristics. We observe much agency among migrants to pursue migration plans, with migration decisions best understood as chains of multiple decisions rather than simple push-pull or two-step models.

We look at the immigration profile of the Austrian People’s Party (ÖVP) and ask whether it can be considered an anti-immigrant party by systematically analysing the party’s electoral manifestos from 1994 to 2019. The article identifies an amplification of restrictive positions after 2017. In the electoral manifestos of 2017 and 2019, immigration plays a key role, with a strong focus on Muslim immigrants and their descendants as a ‘cultural other’. A major driver of the explicit anti-immigration profile was the restructuring of the ÖVP into a leadership party.

Introduction to special issue, reflects on the knowledge production in the sociology of migration. We emphasise the continuous and changing challenges of knowledge production in the sociology of migration, taking a historical perspective to outline how contemporary contributions are a development of previous work. We observe an unprecedented willingness by researchers to challenge earlier perceptions of “immigrants” as a homogenous population, – something largely banished to populist political discourse these days. We identify contributions to the reflexive turn, but also and increasing focus on specific social phenomena and the dedication to finding solutions to societal challenges such as inequality or social cohesion.

We examine the relationship between attitudes to foreigners and the share of foreigners at the occupational level. Using a question from the Swiss Household Panel, we show a negative association between the share of foreigners in one’s occupation and positive attitudes to foreigners: Workers seem to react to competition with foreigners. When we add the occupational unemployment rate, objective pressures in the labour market appear as relevant as contact at the occupational level. Both factors – particularly objective pressures – are probably accounted for by sorting on job quality. We also show that the association between the occupational share of foreigners and attitudes decreases for workers with better job prospects. This implies that workers welcome foreigners to overcome labour market shortages.

This article uses 24 questions on potential neighbours to systematically vary the characteristics of immigrants in a representative survey in Switzerland, 2013. Respondents systematically consider immigrants from distant cultures and those more likely to receive welfare benefits as more threatening. At the same time, those who feel threatened by one kind of immigrants also tend to feel threatened by others. Questions about immigrants in the generic sense likely capture the right correlates, but they may miss differences in the level of threat evoked by different immigrants.

Little research has examined mainstream parties and their public stances on immigration. Drawing on a political claims analysis of 7 countries between 1995 and 2009, we present the salience, position and overall coherence of claims made by mainstream parties on immigration control and immigrant integration. Mainstream left parties adopt a more positive/expansive position on immigration and exhibit higher levels of coherence than centrist and right-wing parties. We also show that the impact of extreme-right parties (ERP) on the political claims of mainstream left parties seems to be limited. Our conclusions highlight that immigration does not necessarily constitute a cross-cutting cleavage across mainstream left parties.

We examine how proportional changes in residential context are associated with changes in attitudes towards immigrants using data from the Dutch LISS panel and fixed-effect models, measuring the composition of neighbourhoods at the level of four-digit postcodes. A larger change in the proportion of immigrant residents is associated with more positive views on immigrants among natives. It is particularly a change in the proportion of visible non-Western immigrants that appears to be relevant for changes in attitudes. We find little evidence for ‘defended neighbourhoods’ in the Netherlands in the years under consideration.

The literature on attitudes to foreigners and immigrants focuses on Western countries. This article tests broad insights from Western countries in South Africa, an important validity check of the theories. I used data from the 2013 SASAS and the 2013 WVS and show that, in line with research on Western countries, individual personality is associated with differences in attitudes; people in vulnerable positions and those who lack a personal support mechanism are more likely to oppose immigrants. Research on attitudes to immigrants appears to generalize to non-Western contexts.

A systematic assessment of various methods to position political parties on immigration in Austria, Belgium, France, Ireland, the Netherlands, Spain, Switzerland, and the UK, between 1993 and 2013. We find high levels of consistency between expert positioning, manual sentence-by-sentence coding, and manual checklist coding; and poor or inconsistent results with the CMP, Wordscores, Wordfish, and the dictionary approach. An often-neglected method – manual coding using checklists – offers resource efficiency with no loss in validity or reliability.

To what extent do political parties in South Africa politicize immigration? We systematically analyse the party manifestos of all major parties in post-apartheid South Africa. Although we can expect high politicization of immigrants in new democracies, most party manifestos do not treat immigration at all. If parties in South Africa treat immigration in their manifestos, they tend to take relatively inclusive positions, focus on immigrant integration rather than immigration control, and use instrumental frames. It appears that the nation-building project of a post-apartheid South Africa has not led to an increased politicization of immigration by political parties qua parties, although individual politicians certainly play a role

We assess who among migrants is likely to choose unauthorized migration. At the individual level, unauthorized migration in a context of circular migration is linked to being young and male – interpreted as risk-taking individuals – and being free of social responsibilities like having a partner or children. Social responsibilities appear to moderate the impact of risk taking on choosing unauthorized migration.

I present a new representative survey on participation in the 2015 municipal elections in the Canton of Geneva, Switzerland, and predict electoral participation with logistic regression models. Most immigrant groups vote less than the majority population. Social origin (resources), political engagement, civic integration and networks, as well as socialization are associated with differences in electoral participation, but contrary to some recent studies, substantive differences between nationalities remain.

We use claims-making analysis to capture how immigrant groups are differentiated in seven Western European countries. We find that Muslim-related claims-making is associated with the parliamentary presence of anti-immigrant parties and the policy topic under discussion. By contrast, the evidence for policy-oriented and socio-structural explanations is inconclusive.

This article explores how immigrants and their integration are debated across citizenship regimes, with a focus on ‘voiceless’ groups without formal franchise and a precarious residence status: asylum seekers, refugees, and irregular immigrants. Having an ethnic citizenship regime is associated with more claims about voiceless immigrant groups. At the same time, the association between immigrant group size and the extent to which immigrant groups are politicized is moderated by the citizenship regime.

We present a meta-analysis of 738 correspondence tests in 43 separate studies conducted in OECD countries between 1990 and 2015. In addition to summarizing research findings, we focus on groups of specific tests to ascertain the robustness of findings, emphasizing (lack of) differences across countries, gender, and economic contexts.

We examine individual attitudes towards equal opportunities for foreigners and Swiss citizens, using cross-sectional data from the Swiss Household Panel. Individuals with low levels of education tend to oppose foreigners, while the opposition by individuals with high levels of education increases with the risk of unemployment. Values and beliefs explain the negative attitudes of individuals with low levels of education, but not the association with the risk of unemployment for individuals with high levels of education. Clearly, both values and economic factors are important for explaining attitudes towards foreigners.

We provide a systematic and truly historical assessment of immigration and integration policy in Switzerland: between the foundation of modern Switzerland in 1848 and 2014. The most recent MIPEX questionnaire was used to provide a systematic and multidimensional portrait of how immigration and integration policy has evolved in Switzerland. Using these data, we identify three distinctive periods (expansive, restricting, expanding), and argue that the changes in policies reflect the fact that immigrants are increasingly accepted as a permanent feature of Swiss society.

It is possible to increase the validity of research by recombining individual indicators of existing indices. This approach is demonstrated by using data from the widely used Migration Integration Policy Index (MIPEX), recombining some of the 148 indicators to approximate Koopmans et al.’s (2005) two-dimensional conception of citizenship models. The recombined MIPEX data match the desired conception of citizenship models and can be applied to all countries covered in the MIPEX. For the first time theoretically predicted ethnic-pluralistic citizenship models (segregationism) are observed.

In this article we examine the potential drivers of variations in the opinion-policy gap on immigration in seven countries (1995–2010). We analyse the effect of the politicization of immigration on this opinion-policy gap. The strength of anti-immigrant parties is unrelated to the opinion-policy gap on immigration. The salience of the issue and the intensity of the public debate are associated with the opinion-policy gap, and the combination of negative attitudes with extensive media coverage seems particularly conducive to policy congruence.

To what extent does the source language of a text affect automatic approaches to coding party manifestos? Compares German-language and French-language manifestos using a keyword-based dictionary approach and Wordscores. Because of language differences, both stemming and particularly stop words are important to obtain comparable results for Wordscores.

Women’s representation in national parliaments is examined using a large cross-national sample. In line with some recent contributions, this article finds that the proportion of women in parliament is explicable in terms of culture—particularly attitudes towards women as political leaders. Once controlling for regional or cultural differences, the provision of voluntary party quotas does not appear to be significant at the national level.

This article presents a new conceptualisation and measure of political representation to complement conventional approaches. Individual representation scores place the individual rather than the legislature at the centre, providing a fresh perspective on the relationship between inequality and representation. They are calculated by comparing first the position of the individual with other citizens, and second the position of the individual with the legislature. The article outlines how to make sense of individual representation scores and includes an empirical example.

This article examines the relationship between levels of gender representation and levels of ethnic group representation in national parliaments. Taagepera (1994) and Lijphart (1999) predicted that because of shared mechanisms and covariates levels of representation in the two forms should be positively correlated. There is no evidence of an association between levels of gender and ethnic group representation. Representation scores tend to be higher in the forms of representation that are thought to be more salient.

This paper compares the levels of ethnic group representation in parliament in 95 democracies. Considering both electoral and cultural variables, the results cast doubt on whether the role of the electoral system in shaping political representation is dominant. In contrast to what much of the literature suggests, once controlling for the ethnic make-up of society and cultural attitudes, electoral aspects seem of little significance. Levels of ethnic group representation are best explained with cultural variables, in particular liberal attitudes towards marginalised groups in society.

A computer simulation is used to empirically test Milbrath’s 1965 framework of political participation. It is found that both political institutions and social capital are significant contributors to political participation. Rather than the time spent in a community, personal contacts appear to be more important for political participation.

This paper addresses the integration of immigrants and other societal groups from a conceptual point of view. With increased conceptual clarity and by working toward an objective definition as far as possible, the paper creates a possible foundation on which indicators of integration can be built. Integration is conceptualized as proximity, and a distinction is drawn between the integration of groups and individuals. It is argued that integration should be understood as assimilation in relevant dimensions, whereas in other dimension significant differences are accepted.

This paper examines the reliability of the Migrant Integration Policy Index (MIPEX) as a scale. The results of the reliability analysis suggest that overall, MIPEX is a reliable scale. Moreover, the individual strands are also reliable, although in most instances the scales could be improved by removing specific items. In contrast, however, most of the dimensions identified are not reliable. It seems that the number of indicators in MIPEX could be reduced, and the data are probably better presented in a different way than the six strands MIPEX uses.

This edited book brings together the work of several scholars affiliated with the MOVE Network on mobility studies. Instead of assuming a seamless world of flows, as is common in mobility studies, the volume highlights questions of power, inequality, and moorings as integral to mobility of capital, goods, images, practices, or people. My role was managing the publication, and trying to encourage contributors to be more systematic, precise and coherent in their accounts of mobility.

Despite this, there is unease with immigrants. Using a representative survey, I show that most Swiss citizens are not strongly opposed to immigrants, but there are clear differences in how various immigrant groups are perceived.
