Austin Kocher

Austin Kocher, a data researcher, geographer and Substack writer, will write a monthly immigration column for Documented NY, a New York City outlet covering immigrant communities. Kocher has spent nearly two decades studying the U.S. immigration enforcement system, and the column follows an earlier interview the outlet conducted with him.

Researcher Austin Kocher has published his weekly roundup of US immigration enforcement statistics, dated October 3, 2026. The recurring digest compiles recent data on arrests, detentions, and immigration court activity, and is followed by advocates, journalists, and analysts tracking how enforcement levels shift week to week under current policy.
