The word "address" doesn't appear on the link I provided. Nor in the page where that site define homelessness. So I fail to see how you deduce that the statistics are compiled with your definition of homelessness. Again, read the links. (And it's not only shelters and street, either.)

"Experiencing homelessness" may not be the same as "being homeless", but it is a sure sign of strong poverty, of unreliability of housing access. It is an indicator of absolute poverty.

And 1.5% of Americans experiencing homelessness every year is reality, as frightening as the 2% that sleep in jail every night (another indicator of poverty)
