(sorry, was not done posting before your previous response) 
I do not think that blood quantum is tracked anywhere in the states homeless data system, however here are some stats from the system regarding people that Identify as Hawaiian. 

In 2015 :  30.5% - 4,554
in 2014 : 39% - (number not listed - I believe it was close to or over 6,000)
2013 : 29% - 4,584
2012 : 28% - 3,943

There are a number of people in homeless services that are also on the DHHL waiting list. i would have to do some digging, and not even sure there is a direct cross reference available. That might be info we would have to ask in updating records / data.  

My organization also tracks data from the homeless shelters, and just taking a stab at the numbers based on our experiences with what we manage, I would safely say that maybe 1/3 or more of the Hawaiian Homeless, qualify for DHHL
