The map, not the score: place-based risk terrain and the records it concentrates
United States (multi-state, sequential): Fort Worth, TX (2016 study); Richmond, VA (2019 open-source deployment study); New Hampshire, three regions (2018–2023 federal grant, the only documented operational use); vendor-claimed advisory work in Arkansas, Washington, and Oregon; 2025 protocol jurisdiction under recruitmentA nonprofit maps cities into small grid cells and models which places will see child maltreatment next, from crime, blight, and the built environment — never scoring a family, never touching a caseworker's screen. In Richmond, the builders' open-source model put ~70% of held-out maltreatment events in its top risk tier (double the density baseline) covering just 10% of the city — and their own published audit reported the model does not generalize across neighborhoods of differing racial composition, despite race being excluded from the features. New Hampshire is the one documented operational use: inside a 2018–2023 federal grant, coalitions targeted outreach and issued funded RFPs where the maps pointed. No independent outcome evaluation of any deployment exists, and the atlas's own structural reading names the quiet loop: attention goes where the map points, reporting can rise where attention goes, and next year's model trains on the records that attention wrote.
