FDIC研究信息系统（RIS）数据集是美国联邦存款保险公司（FDIC）通过其FOIA页面公开分发的研究信息系统的精选Parquet快照。该数据集是一个关系数据库，涵盖所有FDIC insured机构的银行结构和财务数据，主要数据来源包括：银行结构数据（如机构名称、章程类型、位置、RSSD ID）、呼叫报告数据（来自监管申报的财务报表）、财务比率（从呼叫报告派生的绩效指标）、失败/援助数据（记录银行失败或接受FDIC援助的情况）以及结构变化（如合并、收购、章程转换）。数据集以季度CSV快照形式发布，覆盖时间范围从2006年第一季度至今，并转换为Parquet格式以便高效处理。数据集包含多个配置表，例如RAT（财务比率）、STRU（银行结构数据）、MERG（合并和结构变化）、CDI（合并财务数据）和FTS（财务时间序列），每个表按季度存储为Parquet文件，文件名格式为<TABLE><YYMM>.parquet。数据更新频率为季度，FDIC通常在季度结束后约45天发布新数据。数据集采用CC0-1.0许可证，底层FDIC RIS数据为美国政府工作，不受版权保护。The FDIC Research Information System (RIS) dataset is a curated collection of Parquet snapshots from the FDIC Research Information System, which is publicly distributed by the FDIC through its FOIA page. This dataset serves as a relational database containing bank structure and financial data for all FDIC-insured institutions. Key data sources include: bank structure data (e.g., institution name, charter type, location, RSSD ID), call report data (financial statements from regulatory filings), financial ratios (performance metrics derived from call reports), failure/assistance data (records of banks that failed or received FDIC assistance), and structural changes (such as mergers, acquisitions, and charter conversions). The dataset is published as quarterly CSV snapshots covering the period from Q1 2006 to the present, and has been converted to Parquet format for efficient processing. It includes multiple config tables, such as RAT (financial ratios), STRU (bank structure data), MERG (mergers and structural changes), CDI (consolidated financial data), and FTS (financial time series), each stored as Parquet files per quarter with filenames following the pattern <TABLE><YYMM>.parquet. Updates are released quarterly, with the FDIC publishing new data approximately 45 days after the end of each quarter. The dataset is licensed under CC0-1.0, and the underlying FDIC RIS data is a U.S. government work not subject to copyright protection.
