Murray plans to announce news of the data at a luncheon Wednesday for state veterans' service officers. He said in a statement that veterans "deserve to have a safe place to call home."
The data is based on a count of homeless veterans by the Veterans Affairs and Housing and Urban Development departments. The count was conducted on a single night in January 2012, and compared with previous single-night annual counts. The 1,181 people counted in 2012 represented a 7 percent decline from 2011 and a 26 percent decline from 2010.
Murray has previously announced new federal funding to hire more housing counselors and fund more housing vouchers.
