Baker did see an influx of New Orleans residents during the immediate aftermath of Hurricane Katrina but as of January 2007 only about 1,000 to 2,000 displaced families remain in Baker and most reside in temporary housing in the form of Federal Emergency Management Agency provided trailers, as stated above most displaced residents plan on returning to New Orleans or at least leaving Baton Rouge so the long term impact of Hurricane Katrina on Baton Rouge and surrounding areas is expected to be minimal.
