Childhood lead data is scattered. Help us pull it together.

Roughly half of U.S. states bury their childhood blood-lead results in slide-deck dashboards, locked portals, and one-off PDFs. There is no single public picture of where American children are actually being exposed. We are building one. If you know where your state, county, or city keeps its numbers, send us the link.

Why this is worth your two minutes

Lead exposure is almost entirely preventable, and the single best lever is knowing where it is concentrated. Health departments collect that data, but it is published unevenly and rarely in a form anyone can actually use. Every working link you send makes the map more honest for the next parent who types in their ZIP code.

What counts as a useful source

State or county elevated-blood-lead datasets. Anything with counts or percentages of children tested and found elevated. ZIP code or census tract level is gold. County level still helps.
Health-department dashboards and reports. Even a Tableau or ArcGIS dashboard with no download. Send the link and we will work out how to read it.
Surveillance reports, audits, or studies. Annual childhood lead surveillance PDFs, academic papers with local breakdowns, FOIA responses you have already gotten back.
You work in public health and know the real source. That is the most valuable submission of all. Point us at it, and leave your email if we can ask a follow-up question.
