A Dutch study explores a key barrier to social integration: strong in-group preferences. One hopeful exception: young people don’t have strong preferences for people of their own ethnicity when it comes to sports activities. In PNAS Nexus: academic.oup.com/pnasnexus/ar...

Overall, our paper underscores the pervasiveness of ingroup preferences. It’s difficult to tackle segregation by just targeting meeting opportunities. Measures to support preference change are also needed (e.g., programs promoting tolerance and acceptance).

Experiment 3 shows that respondents prefer their ingroups to a similar degree, regardless of whether the composition of their entire club or the team is concerned (with whom they would spend most time). This suggests that segregation likely ‘adds up’ at each decision node in the setting selection.

These ingroup preferences are stronger among individuals who are currently part of neighborhoods or civic organizations with larger proportions of ingroup members.

Older individuals prefer settings where more people are above 50 and Dutch people without a migration background prefer settings with fewer people of Turkish or Moroccan origin. The only exception are individuals without university education, who display no ingroup preferences regarding education.

For example, respondents with a college degree were on average willing to travel 6 minutes further from their neighborhood to key amenities or from their home to a civic organization if that would mean the respective setting had 75 instead of 25% college-educated members.

Experiments 1 & 2 then showed that people consistently prefer settings with more ingroup members. These preferences are sizable and our experimental setup allows us to express them in terms of additional travel time they are willing to incur.

First, we asked respondents about the composition of their current neighborhoods and organizations and the composition of the people they regularly interact with. For all dimensions studied (age, ethnicity, education), segregation is stronger in civic organizations vis-à-vis neighborhoods.

We fielded survey modules including three conjoint experiments in two high-quality samples of the population in the Netherlands (LISS and TRIAL). What are the findings?

1

Kasimir Dederichs @kasimirdederichs.bsky.social · 23d

We identify ingroup preferences using a set of conjoint experiments, looking at how individuals choose between neighborhoods and civic organizations (e.g., sports clubs, cultural associations) with different social compositions.

Kasimir Dederichs @kasimirdederichs.bsky.social · 23d

Many people live their lives in social bubbles, i.e., segregated settings that offer little opportunity for intergroup contact. Such segregation may emerge from ingroup preferences or opportunity constraints. Both are difficult to distinguish by only looking at the social settings people end up in.

Ansgar Hudde @hudde.bsky.social · Apr 15

Ab in den Druck!🎉

Mein Buch „Wo wir wie wählen: Politische Muster in Deutschlands Nachbarschaften“ ab 18.06. bei Campus

Eine politische Landkarte🇩🇪 basierend auf Wahldaten, Sozialstruktur & Eindrücken vor Ort

Jetzt vorbestellen—in eurer Lieblingsbuchhandlung oder hier www.campus.de/buecher-camp...

Das Bild zeigt die Rückseite des Covers:

Hat sich Deutschland politisch auseinandergelebt? Grenzen sich Anhänger der unterschiedlichen politischen Gruppen auch räumlich vermehrt voneinander ab? Finden wir politisch typische und untypische Orte eher in den Metropolen, in den mittleren und kleineren Städten oder auf dem Land? In Ost- oder in Westdeutschland? Mit einem einzigartigen Datenschatz zum Wahlverhalten in allen 94.000 Wahlbezirken Deutschlands geht Ansgar Hudde diesen Fragen nach und entdeckt: Die Mehrheit der Deutschen lebt nicht in politischen Blasen, sondern in Nachbarschaften, deren Wahlverhalten grob dem Bundestrend entspricht.

Das Buch verknüpft die Analyse von Wahlergebnissen mit sozialstrukturellen Daten und Gesprächen vor Ort und zeichnet dadurch kenntnisreich Lokalporträts ausgewählter deutscher Orte. Hudde identifiziert vier Wahlmuster in Deutschlands Nachbarschaften: das politische Typischdeutschland, vor allem in westdeutschen Klein- und Mittelstädten, das Konservativ-Wahlmuster im ländlichen Bayern, das AfD-trifft-Linke-Wahlmuster in Ostdeutschland jenseits der Großstadtzentren und das Grün-Links-Wahlmuster in den zentrumsnahen Vierteln von Metropolen und Universitätsstädten. Wer diese Wahlmuster kennt und ein Bild von den charakteristischen Orten und Nachbarschaften vor Augen hat, kennt nicht nur Deutschlands politische Landkarte, sondern gewinnt auch ein tieferes Verständnis der Bundesrepublik insgesamt. Eine aufschlussreiche Analyse, die auch die Bundestagswahl 2025 einschließt!

»Ansgar Hudde entwickelt in seinem Buch eine Kartografie des Wahlverhaltens, die eindrücklich zeigt: Orte und Regionen machen einen Unterschied. Deutschland tickt sehr anders, je nachdem, wo man sich befindet. Eine willkommene Landkarte zur Navigation durch die politische Landschaft.« Steffen Mau

While there are certainly organizations out there working very hard and successfully to promote integration, our findings suggest that overall, social sorting dynamics remain pervasive in civic life - both across and within civic organisations.

... ethnic majority members form fewer social connections in organizations with larger shares of ethnic outgroup members and are more likely to leave them. This increased dropout risk can partially be attributed to their weaker social integration in those organizations.
