Authenticated Pseudonyms

A system for creating provably unique pseudonyms that can't be linked back to their creator.

Authentication Authorization

Anonymous Credit Tokens

A privacy-focused micropayment system for web APIs that doesn't compromise user anonymity.

Data Science

Empirical projects, downloadable datasets, and visual reports built to be inspected rather than merely described.

Latest analysis

Unionization and median household income across U.S. states

Using BLS union membership rates and Census ACS 1-year income estimates for 2024, this project builds a 50-state dataset and runs two cross-state OLS regressions — one on nominal median household income, one on income deflated by the BEA 2024 Regional Price Parities — then publishes an auditable artifact set with raw inputs, processed outputs, checksums, and provenance.

Slope (nominal) $1,256

Per +1 pp of union membership, before adjusting for state cost of living.

Slope (RPP-adjusted) $537

Same regression after dividing income by the BEA Regional Price Parity (US = 100). Positive slope, compressed by roughly 57%.

R-squared 0.292 → 0.124

Fraction of cross-state income variation explained by union density alone, before and after RPP adjustment.

Coverage 50 states

Aligned to 2024 for BLS union rates, Census ACS income, and BEA Regional Price Parities.
