Top 10 US States by FDIC-Insured Bank Concentration
US states ranked by FDIC-insured bank count and total assets from current Call Report data.

Research question
Across the US states, which jurisdictions anchor the largest concentrations of FDIC-insured banking activity by institution count and aggregate assets, and how do the average health-grade distributions of those state banking sectors compare?
Methodology
This ranking reflects the data currently in our database, sourced from the agency referenced in the citation below and updated automatically as new filings are processed.
Coverage and exclusions: the source agency occasionally suppresses values for confidentiality, small sample size, or quality control, and suppressed rows are excluded from this ranking rather than shown as zero. If the agency later revises a figure, the revised value replaces the old one automatically the next time our data is refreshed.
Data provenance: we pull each release as it becomes available and normalize it into our database; a later release simply supersedes the one before it, so readers never see a mix of old and new figures on the same page.
Comparability across years: when the source agency revises its release schedule, definitions, or coverage, we note the affected years on the methodology page so readers can compare like-with-like rather than across a changed measurement.
Editorial governance: a named editor reviews every ranking page before publication (see the byline above). If an entity disputes a figure attributed to it, corrections are checked against the official source record before any change is made.
Every number on this page can be traced back to its source by following the entity links and the citation below, so independent verification never requires anything beyond the original public source.

Findings
Top entity in the ranking
The top-ranked record in this dataset is Ohio, with a value of 5,191,490,334 on the Aggregate assets ($) column. The full top-10 set is rendered in the table above. Every value comes directly from the current dataset; no number is hardcoded into this page. When the U.S. Federal Deposit Insurance Corporation publishes a revision, the ranking and the prose around it update automatically.
Distribution shape
The gap between the top-ranked record (5,191,490,334) and the 10th-ranked record (581,849,278) characterizes how concentrated the top of the distribution is. Where the top value is many multiples of the median value of the visible set, the population is highly concentrated, a small number of entities accumulate the bulk of the measured quantity. Where the top and bottom of the visible set are close together, the distribution is relatively flat across the top end. The full distribution beyond this top-10 cut is summarized in the aggregate context section below and explored in the linked entity profiles.
Aggregate context
Across the full population behind this ranking, here are the summary statistics: how many records exist in total, the sum of the ranking metric across all qualifying records, and the mean per-record value. The methodology page documents the exact filter applied (records with null or zero values on the ranking metric are excluded). This aggregate row is computed from the same dataset that powers the ranking above.
Source provenance
The records in this ranking originate from U.S. Federal Deposit Insurance Corporation, specifically the FDIC Quarterly Banking Profile (state-aggregated). PlainBankData ingests the source vintage published by the agency and keeps this page current, there is no static export carrying stale numbers, and a newly published dataset is reflected here within hours. The methodology page documents the source URL, the vintage date, and the steps applied to prepare the data.
Why this ranking matters
Rankings like this one let a reader scan a population quickly and identify outliers, concentrations, and patterns that warrant deeper investigation. The detail pages linked from each entity in the table above give the full per-entity context: time-series history where available, related metrics from adjacent tables, and links onward to the underlying source records. The methodology page explains how an entity earns inclusion in the dataset and how the ranking column is computed at the source.
What this analysis cannot tell us
State aggregations key on the state where the FDIC-insured bank's headquarters is registered, which can differ substantially from the geographic footprint of the bank's branch network and customer base. Money-center states such as New York, Ohio, and North Carolina host headquarters of nationally-active multi-state banks whose assets reflect activity well outside the headquarters state. Conversely, states with smaller aggregate assets relative to population may simply be home to fewer headquartered banks while being heavily served by branches of out-of-state banks. The average health-score column is a state-aggregate of bank-level health scores computed by PlainBankData from FDIC capital-adequacy and asset-quality ratios; the average is unweighted by bank size, so a state with one large stressed bank and many small healthy banks will show a higher average than a deposit-weighted measure would. Cross-state comparisons should consider per-capita banking density, the mix of headquartered versus branch banks, and the geography of consumer banking choice alongside this aggregate.
