82,000 homeless on a population of 9,818,605 [2]; 0.835%
I just compared it to the 2012 stats for The Netherlands (highest homeless count in 2012).
27,300 homeless [3] on a population of 16,779,575 [4]; 0.163%
That was a bit surprising to me. It looks like there are 5 times more homeless per capita in LA than in The Netherlands...
