The Seattle king county survey also found out that 80% of those homeless lived in pioneer square before becoming homeless. Definitely fishy if you know the city.
Do you have a source? Closest I can find is from 2016, and it's 25% of in-county zip codes equalling Pioneer Square, not 80% of all:
"The records show that more than 8,000 clients [of any homeless/housing services tracked by All Home] listed their last ZIP code as 98104, which covers Pioneer Square and downtown. That’s about 25 percent of all clients who gave King County ZIP codes. Putnam says clients sometimes list ZIP codes for the shelters where they last stayed or the neighborhood where they’d been seeking services."
