Concerned about mass migration in the U.S.? Good. Me too.
TL;DR: Christian organizations make up the vast majority migrant resettlement in the US. Accounting for roughly 70% to 80%. Jewish organizations make up about 5%. While NGOs make up roughly 15%.
The structure of the resettlement programs matters here because the system is centralized through a small set of national agencies (VOLAGs), most of which are faith-based.
A quick breakdown of U.S. refugee resettlement by over roughly the last 40+ years (post-1980 Refugee Act) clearly shows Christian organizations as the vast majority of all resettlements. But that shouldn't be surprising as Christianity is the largest religion in the U.S.
Catholic
Primary organization: U.S. Conference of Catholic Bishops (via Migration and Refugee Services + Catholic Charities network)
Share of U.S. refugee resettlement: ~25–35% annually (often the largest single share). Estimated total (since 1980): ~900,000 to 1,000,000+ refugees
Why they dominate scale:
The Catholic system operates as a highly centralized national network with diocesan infrastructure in nearly every major U.S. city. That gives them unmatched placement capacity, especially for large family units and long-term integration services.
Protestant (Mainline + Evangelical)
Primary organizations:
Church World Service
World Relief
Episcopal Migration Ministries
Lutheran Immigration and Refugee Service
Combined share: ~40–50% (when aggregated across all Protestant agencies). Estimated total (combined): Likely comparable to or exceeding Catholic totals when taken together, but fragmented across multiple organizations.
Key structural point:
Protestant resettlement is decentralized. No single Protestant agency rivals the Catholic system alone, but collectively they form the largest overall religious bloc in refugee resettlement.
Jewish
Primary organization: HIAS
Share of U.S. refugee resettlement: typically ~5–10%
Estimated total (since 1980): hundreds of thousands, though smaller than Christian networks
Notable context:
HIAS is one of the oldest refugee organizations in the world. It originally focused on Jewish refugees but now resettles people of all backgrounds. Its footprint is smaller in volume.
Summary:
Largest single organization: Catholic (USCCB)
Largest combined denomination: Protestant (due to multiple agencies)
Smaller but historically influential: Jewish (HIAS)
The U.S. refugee resettlement programs have been dominated by Christian organizations (Catholic + Protestant), which together account for the clear majority of placements over the past four decades. Jewish participation remains consistently smaller in scale.
