Population by year:
2019: 978,763
2020 high estimate for Jan 1 (996,369) - https://austin.culturemap.com/news/city-life/01-15-20-austin...
2020: 961,855 (Census, low mark)
2023: 979,882
2024 (estimated high mark): 986,928
So yes, the population cratered from a high in early 2020. This brought down prices with a 2 year lag, as owners started to get rid of empty units. The prices will come right back up now, that the population is recovering.
