Trailers aren't the only way FEMA has been helping residents since the storm. Certain individuals have been eligible for rental assistance under the Stafford Act. Housed in Houston, San Antonio, Atlanta, Memphis, Dallas and throughout America, rental assistance is supposed to provide a bridge from disaster to recovery.

FEMA provides rent to evacuees at market rates anywhere in the country for up to 18 months. To qualify, beneficiaries must have been displaced by Katrina or Rita and their homes must be uninhabitable. The rental assistance counts toward a $26,200 cap for applicants receiving FEMA disaster benefits. FEMA has asked beneficiaries to demonstrate they are fixing their homes or working toward returning to a self-sustaining living arrangement.

As of August, the rental assistance program had helped 604,511 families at a cost of $3.7 billion, not including long-term sheltering and travel trailers.

Eighteen months after the storm, on February 28, 2007, FEMA rental assistance will come to an end. Even though this seems like a very generous benefit and provides ample time for people to reestablish their lives, thousands will still be affected when the program comes to an end. ACORN has of course filed suit.

In August 2007 HUD assumed responsibility for the FEMA rental assistance program and said it will continue until March 2009. The HUD announcement said 30,000 families are receiving this benefit. FEMA reports 44,000 travel trailers are in use. This is in addition to the people who were living in housing projects and section 8 housing before the storm.

 In 2008 FEMA plans to collect a $50 per month "stipend" for families continuing to use rental assistance.

No one is saying (willing, able, etc.)  how many people are still using this benefit. Since it is being administered across the entire nation its hard to pull together a specific answer.
