**Possible improvement:** Filtering/removing outlier values that are likely noise (e.g., due to reporting anomalies or missing data) could make the state-level trends clearer and more accurate.
**Tech:** Built with Python (pandas for data wrangling, Plotly for the maps, and imageio for the animation).

can really see the financial crisis of 2008 where everything went dark blue – especially SW from 2007-2010.

Very fun to watch. Obviously fun to see the 08 crash and 20 covid era.
Really nice to stare and find the “most white” states with the least increase/decrease.
Any chance you can draw this back another 10 years? It would be nice to see state by state changes through the early 90’s, mid 90’s, and dot com bubble. Just for some context of what we have seen the last 20+ years vs how markets moved 30+ years ago.

Y scale incorrect? Says % and has fractional values. Shouldn’t it be +20%~-20% instead of +0.2%~-0.2%

Since we still have covid 19 protections for mortgages in place, we would be at mortgage delinquency percentage at 2008 levels.

Really interesting graphic, thanks for sharing.
Louisiana stood out during the “covid spike” – seems to have been relatively unchanged
