Gender diversity on corporate boards has made measurable progress over the past decade. But the trajectory is uneven, and the headline numbers conceal significant variation by company, industry, and role. We analyzed 7,427 directors across 772 public companies using their most recent SEC proxy filings. Here's what the data shows.
The Headline: 32.5% of Directors Are Women
Women hold 2,361 of the 7,270 board seats with identified gender in our dataset — 32.5%. Men hold the remaining 67.5%.
That figure is up from roughly 12% in 2010 and 20% in 2015, representing genuine structural change driven by investor pressure, Nasdaq listing requirements, and state legislation. But the rate of new female appointments has been declining every year since 2019, which means the aggregate percentage is growing slowly if at all.
The Distribution: Most Companies Cluster in the 30-39% Range
The aggregate 32.5% masks wide variation across individual companies:
| Female Director % | Companies | % of Total |
|---|---|---|
| 0% (no women) | 17 | 2.2% |
| 1–19% | 61 | 8.0% |
| 20–29% | 211 | 27.7% |
| 30–39% | 284 | 37.2% |
| 40–49% | 129 | 16.9% |
| 50%+ | 61 | 8.0% |
The largest single bucket — 37.2% of companies — sits in the 30–39% female range. This is not coincidental. The Nasdaq board diversity rule (effective for most companies by 2023) requires at least two diverse directors, one of whom must be female. A typical 9-person board with three women lands at 33%. These thresholds explain the clustering.
61 companies (8.0%) have reached majority-female representation. At the other extreme, 17 companies (2.2%) still have all-male boards as of their most recent proxy filing.
The All-Male Holdouts
Seventeen public companies field all-male boards. The most notable among larger boards:
| Ticker | Company | Board Size |
|---|---|---|
| SCCO | Southern Copper Corp | 8 |
| SN | SharkNinja, Inc. | 8 |
| MLM | Martin Marietta Materials | 7 |
| GSAT | Globalstar, Inc. | 7 |
| APO | Apollo Global Management | 5 |
| GME | GameStop Corp. | 5 |
| MDB | MongoDB, Inc. | 5 |
Several of these companies have dual-class share structures or controlling shareholders that insulate them from proxy voting pressure. Companies without a controlling shareholder — like Apollo and MongoDB — face escalating institutional investor backlash at each annual meeting.
The Leaders: Companies With Majority-Female Boards
61 companies have achieved majority-female board representation. Among those with at least 7 directors:
| Ticker | Company | Board Size | Women | % |
|---|---|---|---|---|
| ATI | ATI Inc | 9 | 6 | 67% |
| NVT | nVent Electric | 9 | 6 | 67% |
| CAT | Caterpillar | 8 | 5 | 63% |
| MO | Altria Group | 8 | 5 | 63% |
| TSCO | Tractor Supply | 8 | 5 | 63% |
| FFIV | F5, Inc. | 8 | 5 | 63% |
| PH | Parker-Hannifin | 10 | 6 | 60% |
| BBY | Best Buy | 10 | 6 | 60% |
| ULTA | Ulta Beauty | 10 | 6 | 60% |
| HPQ | HP Inc | 12 | 7 | 58% |
Caterpillar and Parker-Hannifin stand out as majority-female boards in traditionally male-dominated industries (heavy equipment and industrial manufacturing). These are not the companies most observers would expect to lead on board diversity.
Industry Breakdown: Retail Leads, Tech Lags
The gender gap varies by industry:
| Industry | Female % | Total Directors |
|---|---|---|
| Wholesale Trade | 35.9% | 181 |
| Retail Trade | 35.2% | 383 |
| Manufacturing | 32.9% | 2,741 |
| Financial Services | 32.3% | 1,588 |
| Transportation & Utilities | 31.8% | 785 |
| Services | 31.6% | 1,107 |
| Construction | 30.1% | 133 |
| Mining | 28.7% | 188 |
| Technology | 26.3% | 57 |
Technology is the most significant laggard at 26.3% — below the aggregate and below every other major industry in our dataset. This reflects the industry's well-documented pipeline problem: the executive talent pool from which boards recruit skews heavily male, and boards tend to recruit from that pool.
Retail (35.2%) and wholesale trade (35.9%) lead in part because these sectors serve predominantly female customers, and boards have made deliberate efforts to align composition with customer demographics.
The Tenure Gap: Women Are Newer to Their Boards
Female directors average 6.5 years of tenure. Male directors average 9.0 years. The 2.5-year gap has structural implications.
It reflects timing. The meaningful acceleration of women onto corporate boards began around 2013-2016. A woman who joined in 2014 has 12 years of tenure today — but the majority of female directors joined more recently, pulling the average down.
The tenure gap matters in two ways:
Leadership roles are lagging. Board chairs and senior committee assignments typically go to longer-tenured directors. Among the 678 board chairs identifiable in our dataset, only 80 (11.8%) are women — well below the 32.5% seat share. Among the 354 lead independent directors we identified, 80 (22.6%) are women — better, but still below parity with seat representation.
Independence rates are high. Female directors are classified as independent at a 93% rate, compared to 75% for male directors. This reflects how most women reached the boardroom: through an external search process seeking independent perspective, rather than the insider paths (founder status, executive promotion) that produce non-independent directors.
The Appointment Trend: Slowing Since 2019
The sharpest insight in the data is the year-over-year trend in female appointments among directors who joined each year:
| Year Joined | Total Directors | Female | % Female |
|---|---|---|---|
| 2019 | 449 | 205 | 45.7% |
| 2020 | 516 | 221 | 42.8% |
| 2021 | 551 | 238 | 43.2% |
| 2022 | 494 | 193 | 39.1% |
| 2023 | 569 | 223 | 39.2% |
| 2024 | 601 | 218 | 36.3% |
| 2025 | 614 | 171 | 27.9%* |
*2025 is incomplete; many proxy statements cover elections held in spring 2025 but some companies have not yet filed.
The share of new board appointments going to women peaked at 45.7% in 2019 and has declined in most subsequent years. The 2025 number will rise as remaining filings come in, but the directional trend from 2019-2024 is clear.
This matters because the aggregate 32.5% is a stock number reflecting all current directors. The flow — who is being added — determines where the aggregate is heading. A declining flow percentage means the aggregate will plateau and eventually decline.
Several factors may explain the trend:
- Compliance plateau. Once companies met Nasdaq's two-diverse-director threshold, urgency around prioritizing female candidates for additional open seats decreased.
- Competing qualifications. Nominating committees now weigh more criteria simultaneously — cybersecurity, AI governance, sector-specific expertise — which may dilute the weight given to gender diversity.
- Macro backlash. Several large institutional investors have scaled back or publicly softened their public diversity voting policies since 2023.
Leadership Roles: The Last Frontier
Of the 678 board chairs identifiable in our dataset, 80 are women — 11.8%. Of 354 lead independent directors, 80 are women — 22.6%.
Both figures trail the 32.5% share of total board seats significantly. The lead independent director gap is smaller because that role typically goes to the most senior independent director, and women who joined boards in 2013-2018 are now accumulating the tenure required. Board chair representation is harder to shift: the chair role often reflects long-standing relationships that predate the current diversity push.
What This Means for Candidates
If you are a female executive targeting a board seat, the data points to specific strategies:
Industry focus. Technology, mining, and construction companies sit below 30% female and face the most pressure from institutional investors. A qualified female candidate in these sectors targets a compressed pool of competitors relative to the pressure these boards face.
Tenure creates leadership openings. The tenure gap means that women with 10+ years of board experience are a small and valuable cohort. If you have already served on one board, your positioning for committee leadership — and for a second seat — is stronger than the aggregate numbers suggest.
The all-male boards are pressured. Institutional investors including BlackRock, Vanguard, and State Street have policies that result in voting against nominating committee chairs at companies without female directors. The 17 all-male boards in our dataset face escalating pressure with each proxy season.
The 30-39% companies are not done. A company at 33% on a 9-person board has 3 women. If 2 male directors approach mandatory retirement or term limits, they may specifically seek women for those seats to maintain their ratio. Companies in the 30-39% range with aging male directors represent near-term opportunities.
The 32.5% figure is a real achievement relative to where boards were a decade ago. But the declining pace of new female appointments suggests the easy gains — companies moving from zero or one to two women — are largely complete. Reaching 40%+ in aggregate will require continued pressure on the laggards and progress in the leadership roles where women remain significantly underrepresented.
