Public portion of the source data for the banking-concentration visualizations
project at
https://github.com/aaron-freedman/banking-concentration. This dataset
assembles regulatory filings from three US bank and thrift supervisors covering
1959–2025 into a single, loadable collection of parquet and comma-separated
values (CSV) files.
Important: three additional files are needed by the full preprocessing
pipeline but are not included here… See the full description on the dataset page:
