Don't know where you came with your figure unless your using the figure of how many veterans make up the US population which happens to be 10%.
Veterans who are Homeless
According to
Veteran Homelessness: A Supplement to the 2009 Annual Homelessness Report
,
released in January 2011 by the U.S. Department of Veterans Affairs and the U.S. Department of
Housing and Urban Development

:
•
An estimated
75,609
veterans (male and female) were homeless on a single night in January
2009.
•
Roughly
160,000
veterans experienced homelessness over the course of the year (about
10%
of the total homeless population
).
•
Roughly
44,000 to 66,000 veterans
are experiencing chronic homelessness.
•
Nearly
one-half
of all homeless veterans on a single night were located in just four states:
California, Florida, New York, and Texas.
•
Almost all
of sheltered homeless veterans are single adults, however
4%
are part of families.
They tend to be younger, African-American, and female.

And a report I read about five years ago from another agency that deals with tracking homeless placed the figure at over fifty percent. Which I am likely to believe than a watered down report from the Veterans agency that doesn't deal with the homeless issue. In other words they're making their crap look good and not stink. Even the article I posted for you above places the number over twice as high as the Vets Administration...
You can believe what you wish to believe but I'll bet the percentages are at least 40-60% of the current homeless population are vets. Most not being accounted for in the statistical reports because the government doesn't want to look bad.
