Methodology

All metrics are calculated from U.S. Department of Labor Form 5500 annual filings. The slice "5,000+ participants · 401(k)" is served from the accepted-generation projection for plan year 2024. Medians use percentile_cont over reported values; zero/null values are excluded from rate-style metrics.
