How to read this release diff

Use the matched-pair tallies for movement; use the year-file table only as coverage context.

  • Every movement count uses the same EIN + plan number in both 2023 and 2024. Plans in only one year are excluded from the direction tallies.
  • Year-to-year differences in total filings reflect release-file coverage and extensions, not a verified count of plan terminations.
  • A higher participant or asset figure can follow hiring, eligibility changes, mergers, investment returns, or reporting revisions. Form 5500 does not name the cause. Methodology

Absolute participant gains and declines on linked rankings require a 10,000 prior-participant floor so ordinary small-plan churn does not dominate national lists.

Site product updates (corrections, features) live on the changelog. Methodology for matching and ranking floors is on methodology.

Every figure on PlainRetire is rendered directly from the Department of Labor's Form 5500 annual return filings, no number is typed in by an editor. See our editorial standards & corrections policy, the methodology behind these numbers, or report a data error.
