Data studies
Original studies built from primary data: government surveys and published provider
research, transcribed into pinned, tested datasets and explained without hype. Every
figure carries its source, lens, and data year, every table downloads as CSV under
CC BY 4.0, and the lead chart and main table of each study can be embedded with
attribution built in.

How every study is built
The same discipline applies to all of them. Figures come from primary sources, the
Federal Reserve's Survey of Consumer Finances, the BEA, the Census Bureau, the IRS, and
named provider research, and are transcribed into version-controlled data modules,
never fetched at build time, so every number changes only through a reviewable diff.
Automated integrity suites pin each figure to its source and enforce the structural
rules the pages describe, down to blocking checks that fail our build if a study and
its paired calculator ever disagree. Projections are computed by the same tested,
decimal-precise engine behind our calculators, with assumptions stated beside every
chart.
Each study refreshes when its sources publish new data: provider research annually, IRS
limits each fall, and the Fed's triennial survey when the next wave arrives (the 2025
SCF, expected in late 2026, refreshes every SCF-based page in one pass). Changes are
recorded in the changelog,
and the full process lives on
how we verify.
Reuse the data
Every table on these pages downloads as a CSV licensed CC BY 4.0: reuse it freely with
attribution to FinExplained and a link, with the underlying figures credited to their
primary sources as each file's header states. Each study's lead chart and main table
are also embeddable as auto-sizing iframes that carry the source line and attribution
link built in, so an embed can never show a figure without its provenance.
