Social Cohesion & Identity

Social Cohesion & Identity

Large-scale immigration has led to unprecedented levels of diversity and rapid demographic change, transforming communities across major immigrant-receiving countries in fundamental ways and challenging closely held notions of national identity, particularly in an era of economic uncertainty. The research here focuses on what policymakers can do to mitigate the destabilizing effects of rapid societal change — especially changes tied or perceived to be tied to immigration — in order to create stronger and more cohesive societies.

The skyline of Singapore

With limited land, low fertility, and a changing economy, Singapore has long depended on immigration to grow its labor force and global competitiveness while preserving national identity. This country profile examines how the nation has managed migration-related challenges in adapting to shifting demographic, economic, and political pressures.

Anti-refugee activists in Austria.

In recent years, vigilante groups opposed to immigration have formed to conduct patrols, stage parades, and even commit violence against asylum seekers and other migrants in Europe, North America, and other regions. Vigilantes often claim that the government has been soft on irregular migration and use performative, symbolically heavy imagery to sway public opinion. This article traces the trends in vigilante movements targeting migrants.

President Donald Trump addresses the nation.

U.S. immigration policy, practice, and enforcement changed dramatically over the first year of President Donald Trump's second term, touching most corners of the immigration system. The government has cracked down on unauthorized immigration in the U.S. interior and at the border, expanded scrutiny of immigrants of all legal statuses, and erected barriers for would-be arrivals. This article provides a sweeping overview of the changes that have taken place and assesses their impacts.

Families from Venezuela in Trinidad and Tobago.

Many Venezuelan migrants in Trinidad and Tobago have found that their situation is more complex than expected as the Caribbean country has largely adopted an enforcement-first approach. Many Venezuelan migrants face stigma and precarity—issues complicated amid escalating tensions between Venezuela and the United States, as this article details. 

A woman and child at the Moldova-Ukraine border

One of Europe’s poorest countries, Moldova has hosted more displaced Ukrainians per capita than any other nation. More than one-quarter of the nearly 7 million Ukrainians who fled since Russia’s 2022 invasion have passed through Moldova. This article provides an overview of the little country shouldering a disproportionate burden even as it is pulled between Russia and the European Union.

In many high-income countries, governments are scrambling to prove they are in control of immigration by tightening the rules on who can enter and stay. While some policies signal toughness, they do not necessarily improve outcomes for either local communities or migrants. This report examines ways to rebuild public trust through integration policy reforms that go beyond control signaling.

La reforma de la ley de movilidad humana de Ecuador impone controles de inmigración más estrictos, vinculando la migración de venezolanos con el aumento vertiginoso de los índices de criminalidad. Sin embargo, esta vinculación no está respaldada por los hechos, y Ecuador debería pasar ahora a una segunda fase en la elaboración de sus políticas: una fase centrada en la integración y el desarrollo de los inmigrantes.
