Actually, the number of homeless people in the U.S. has been decreasing over the past two decades. They might be increasing in some areas, or just becoming more visible, but the total absolute numbers are going down - and the fraction goes down more since the population is going up.

Well, as I mentioned, homelessness has increased nationally every year over the last three years, consecutively.
"Trends in Homelessness
Compared to the previous year, homelessness increased by 3 percent in the 2019 Point-in-Time Count. This marked the third straight year of national-level increases."

My graph only went to 2018, but it's the same data. You can see the first two years of increase on the graph I posted. Yes, it did increase further in 2019 (to 567,715), but we are still well below the levels set in 2007. So... homelessness nationally went down 17% from 2007 to a low in 2016, and then up again 3.2% from that low to 2019.
That's different than the narrative you gave. Even if it had gone down again in 2019, it would still be a problem, and we should still try to address it. But it's important to see that we *have* successfully reduced it from 2007.
The giant map chart thing also shows that homelessness has increased in the states of New York, Washington, Oregon, and California, in particular.
Thus, based on the current and most recent data, what I said is accurate. Homelessness in America is a growing problem.
Why those states? And you're wrong about Washington - it has decreased there. From the site you source,
Since 2007 homelessness overall has decreased, but the ten biggest percent increases have been (in order) South Dakota (+72%), New York (+47%), Idaho (+32%), DC (+23%), Massachusetts (+22%), Montana (+18%), Alaska (+16%), Kansas (+13%), California (+9%), Minnesota (+9%).
Since 2018 which is the recent uptick nationally, the ten biggest percent increases have been New Mexico (+27%), California (+16%), Idaho (+15%), West Virginia (+12%), Kentucky (+11%), Georgia (+10%), Oregon (+10%), Minnesota (+10%), Kansas (+7%), and South Carolina (+6%).
