Could you please link to your source page directly, so it's obvious where you got your data? People here obviously will have questions about the methodology.

Also, what is the bin size on your chart?

(For example, seeing as there was no FDIC in 1934, and local banks would not have been on any kind of registry, I'm sure we'd all like to see whether the dataset attempts to do an adjustment for this or leaves the data raw. Also, the standard for a "bank failure" has changed significantly since the FDIC and associated regulations were established. In case people haven't noticed, SVB is still around and now solvent -- so is it a failure comparable to 1934?)
