A lot of people do not want to deal with the "authorities". Other people may be connected with the helping system. In the USA, some people came up with an idea to help fix that problem. The government agency in charge of these issues is called Housing and Urban Development. That agency requires a homeless count every two years. Organizations such as w:Common Ground are trying to reach out to more people with the homeless counts and use these counts to get a list of homeless people who need some help. Hopefully one of the good things to come from all of that work is there will be better ways to make sure people know about the warming centers.
