Original analysis from the Center for American Progress Action Fund shows that, on average, cities in blue states have lower rates of gun homicides and shooting incidents than comparably sized cities in red states and are seeing larger single-year decreases in gun violence rates in 2023.
I can really only personally speak about Portland, but the decline seems steeper because the increase had been so dramatic.

January to August shooting numbers:
2019 - 276
2020 - 497
2021 - 850
2022 - 898
2023 - 725
So, yeah, a dramatic difference from 2022, but still not back to a pre-pandemic baseline.
If you look at full year numbers:
2019 - 413
2020 - 919
2021 - 1315
2022 - 1309
2023 - 725 (through August)
