An annual study this year by the Pew Hispanic Center, using U.S. census data, estimated that the number of immigrants in Utah illegally dropped by 10,000 between 2008 and 2009 — from 120,000 overall to 110,000. But study authors caution those numbers are within statistical margins of error, so it is possible that no decrease occurred — but numbers suggest illegal immigration is at least slowing to a trickle.
