Common questions
How this is built. Percentiles are modeled for this cohort from federal survey microdata — the Federal Reserve's 2025 Survey of Consumer Finances (released October 2026), the BLS Consumer Expenditure Survey (2024), the Census American Community Survey and BLS Occupational Employment & Wage Statistics (May 2025) — with metro cost-of-living and wage adjustments. As Keeping Up members in this cohort grow, the band blends toward anonymized, aggregated live data (minimum cohort sizes apply; no individual is ever identifiable). Seeded figures are household-level, as in the SCF; live cohorts are individual-level. Amounts are in current dollars. Read the full methodology.
