There are about 12,000 homeless people (the count was 11,890) in Colorado according to a survey taken last summer. A winter count is underway.
Colorado has a population of about 4.7 million people. So about 1 in 400 people in the state are homeless. The definition of homelessness used in the survey includes people with shelter, but not homes. It is not restricted to vagrants sleeping in parks or on the street.
