A University of Washington Center for Human Rights report documents immigration enforcement across the Pacific Northwest during late 2025, with arrests increasing from 250 in late 2024 to 2,250 in the final three months of 2025. Yakima County had 180 arrests per 100,000 residents, the highest rate per capita in the state.
