32 Million Participants Are Owed a Future Retirement Benefit. Here's How We Counted Them.
The retirement industry discusses missing participants constantly. We went looking for the denominator — how many separated participants are out there in total — and could not find it published anywhere.
So we computed it. From the Department of Labor's own public Form 5500 filings, form year 2024: 32.2 million people are entitled to a future retirement benefit they are not yet receiving, across 93,069 plans.
That is not a count of missing people, and we will be precise about what it is before going further, because the overstated reading of this number is the one that deserves to be ignored. But it is the population that missing participants are drawn from, and if you are a fiduciary, a third-party administrator or ERISA counsel, it is the surface your obligation sits on.
The numbers
The Department publishes every Form 5500 filing as bulk public-domain data. Main-form line 6c asks for "retired or separated participants entitled to future benefits." One field, filed under penalty of perjury, by every plan in the country.
Form year 2024, from the "Latest" dissemination file — 225,591 total filings, of which 130,742 are pension plans:
| Pension filings reporting at least one separated vested participant | 93,069 (71.2%) |
| Total separated participants entitled to future benefits | 32,239,902 |
| Total already receiving benefits | 10,884,319 |
| Separated participants with partially vested benefits | 3,533,266 |
The distribution is extremely top-heavy:
| Separated vested per plan | Plans | People | Share of people |
|---|---|---|---|
| 1–49 | 45,068 | 883,227 | 2.7% |
| 50–249 | 33,430 | 3,679,853 | 11.4% |
| 250–999 | 10,003 | 4,783,622 | 14.8% |
| 1,000–4,999 | 3,528 | 7,273,123 | 22.6% |
| 5,000+ | 1,040 | 15,620,077 | 48.4% |
A thousand and forty plans account for nearly half of everyone. That is 0.8% of pension filings holding 48.4% of the population. Whatever the right operational answer is, it is not evenly distributed.
Two further cuts we found more interesting than the headline:
94.6% of plans that report any separated vested participants owe more people than they are currently paying. Not a minority condition. The normal state of a retirement plan is that the queue of people waiting is longer than the line of people being paid.
10,058 plans report more separated vested participants than they have active employees. Those plans cover 7.4 million people. In roughly one plan in nine, the population the plan owes money to is larger than the population currently working for the sponsor — which is the situation where contact information decays fastest, because nobody in the building has a current address for someone who left a decade ago.
Geographically, plans with 250 or more separated vested participants concentrate where you would expect: California (1,590), New York (1,449), Texas (1,047), Illinois (815), Pennsylvania (772), New Jersey (601), Ohio (581), Florida (563).
What this number is not
It is not 32 million missing people. Line 6c counts everyone entitled to a future benefit and not yet receiving it. The large majority are not missing at all — they are not yet old enough, or have not elected to start payments, or are perfectly reachable and will be paid on schedule. Reading this as a missing-participant count would be wrong, and we would rather say so than let the bigger number travel.
It is the exposure surface, not the incident count. Missing participants are a subset of this population, and Form 5500 does not tell you how large that subset is. We are not aware of any public source that does, which is rather the point.
It is not a compliance judgment about any plan. A large 6c count is a demographic fact about a plan's history and workforce turnover, not evidence that anyone did anything wrong.
We are stating these limits up front rather than in a footnote because a number this size is easy to misuse, including by us.
Why the number matters anyway
Because the Department's guidance attaches duties to this population regardless of how many turn out to be reachable.
Field Assistance Bulletin 2014-01 requires fiduciaries to take specific search steps, in mandatory language, and separately requires that "Plan fiduciaries must be able to demonstrate compliance with ERISA's fiduciary standards for all decisions made to locate missing participants and distribute benefits on their behalf." The 2021 Best Practices guidance closes its list of search methods with "Searching regularly using some or all of the above steps" — which means the artifact is a dated series, not a one-time memo.
And in January 2025, Field Assistance Bulletin 2025-01 made a documented search a condition of enforcement relief: a fiduciary transferring small balances to a state unclaimed property fund gets that relief only where it "has implemented a prudent program to find missing participants consistent with the Department's Best Practices for Pension Plans, and nevertheless has been unable to locate the participant or beneficiary."
Read those together against the table above. Thirty-two million people sit inside an obligation measured by process rather than outcome — and process is only provable with records.
Reproduce this
We think the method matters more than the headline, so here is everything needed to check us.
Data: the DOL's Form 5500 datasets. The 2024 main-form file is at https://askebsa.dol.gov/FOIA Files/2024/Latest/F_5500_2024_Latest.zip. Use the Latest file, not All — All includes amended, duplicate and errored filings.
Fields: RTD_SEP_PARTCP_FUT_CNT (line 6c), RTD_SEP_PARTCP_RCVG_CNT (6b), TOT_ACTIVE_PARTCP_CNT (6a), SEP_PARTCP_PARTL_VSTD_CNT (line 7), TYPE_PENSION_BNFT_CODE (8a, used to select pension filings). The real data dictionary is the *_layout.txt inside each zip — the files the DOL labels "data dictionary" are PDFs of blank forms.
Four things that will trip you up. The CSVs are latin-1, not UTF-8, and a naive read throws. Publication lags roughly 18–24 months to maturity, so the most recent form year is incomplete and should be treated as a leading indicator only. Schedule C — which names service providers — covers large plans only (generally 100+ participants) and only providers paid $5,000 or more, so smaller plans and their administrators are absent from it. And provider names are filer-entered free text truncated to 35 characters, so any provider analysis has to normalise on EIN rather than name.

If you reproduce this and get different figures, we would genuinely like to know.
One thing the data cannot give anyone
Form 5500 reports the count. The named individuals go to the IRS on Form 8955-SSA, which is not part of the public dissemination data.
That distinction is worth sitting with. Every number in this article describes plans, not people. It is possible to size this problem precisely without touching a single person's record — and for anyone building tools in this space, that is not a limitation to work around. It is the shape the work should have.
Frequently asked questions
How many participants are owed a retirement benefit they are not yet receiving?
Based on Department of Labor Form 5500 filings for form year 2024, 32,239,902 participants were reported as retired or separated and entitled to future benefits, across 93,069 pension plans. This is the figure reported on main-form line 6c, aggregated across all pension filings in the DOL's "Latest" public dissemination file.
Does that mean 32 million retirement plan participants are missing?
No. Line 6c counts everyone entitled to a future benefit who is not yet receiving one. The large majority are not missing — they may not have reached retirement age, or may not have elected to begin payments. Missing participants are a subset of this population, and Form 5500 does not report how large that subset is.
Which plans have the most separated vested participants?
The distribution is highly concentrated. 1,040 plans reporting 5,000 or more separated vested participants account for 15.6 million people, or 48.4% of the total, while 45,068 plans reporting fewer than 50 account for 2.7%.
Where does the public Form 5500 data come from and can anyone use it?
The Department of Labor publishes Form 5500 filings as bulk downloadable datasets through its public disclosure program. The data is in the federal public domain with no licence, attribution requirement or commercial-use restriction.
Does Form 5500 identify individual participants?
No. Form 5500 reports counts only. Information identifying separated vested participants is filed with the IRS on Form 8955-SSA, which is not included in the public dissemination data.
