SparkyData develops synthetic demographic datasets calibrated to public statistics, beginning with the New York metropolitan area.

Landing page captured for the 2026-09-04 issue.

Field notes

The stated workflow starts with whole households from disclosure-protected microdata, then calibrates household and person margins simultaneously rather than joining unrelated statistical tables. Additional variables are layered conditionally, and the site says records are validated against two-way joints and held-out statistics. The initial geography is the New York metropolitan area. A featured analysis contrasts 92,000 high-income renter households with alternative counts produced by gross-income and take-home-pay thresholds.
