The Afghan immigrant population in the United States has grown dramatically since 2010, and particularly since the 2021 withdrawal of U.S. forces from Afghanistan. Most Afghans who obtained a green card in recent years have done so through the Special Immigrant Visa (SIV) program, reserved for interpreters and other Afghans who worked with the U.S. government. This article offers data on the approximately 195,000 Afghan immigrants in the United States.

Severe weather, rising seas, and other consequences of global climate change are affecting the way people live, work, and move around the planet. While there is no clear, direct line between the impacts of climate change and changing human movement, there are indications that the warming planet is indirectly creating or altering patterns of migration. Our podcast Changing Climate, Changing Migration dives deep into the intersection of climate change and migration to separate fact from fiction.

The changing nature of conflict has brought an uptick in gender-based violence in war-torn countries, with instances of rape particularly common in conflict zones. While many women leave their countries to escape such violence, setting off on the journey is no guarantee of safety, as they are vulnerable to further gender-based abuse in transit and at destination. This article explores the rates of gender violence among refugee, asylee, and migrant women, and examines supports available to survivors in the United States.
