If you are in the US, you may be observing a local trend rather than one representative of the whole country. It's very difficult to measure, but this site has an estimate: https://www.statista.com/statistics/555795/estimated-number-...

It shows about a 12% drop in homeless people 2007-2019. The US population overall grew just under 10%, too, so the drop on a per capita basis is higher than that. I imagine 2020 led to a large increase again, though. I also can't vet their sources without registering so take it with a grain of salt.
