HUD puts out an annual report on homelessness that does a great job of capturing the homeless epidemic in America.
You can check out the entire report here:
The 2015 Annual Homeless Assessment Report (AHAR) to Congress
But here are some of the bigger points:
In January 2015, 564,708 people were homeless on a given night. Most (69 percent) were staying in residential programs for homeless people, and 31 percent were found in unsheltered locations.
Nearly one-quarter of all homeless people were children, under the age of 18 (23 percent or 127,787).
Nine percent (or 52,973) were between the ages of 18 and 24, and 68 percent (or 383,948) were 25 years or older.
