Scattered data. Clear answers.
DatumHorizon turns fragmented public data into clear, sourced web pages that anyone can use for free.
What we do
Public information is often published as raw feeds, spreadsheets, or scattered pages. DatumHorizon collects selected public datasets, checks them, and presents each one as a focused page: the answer first, the records beneath it, and the source beside the numbers. Every page shows when its data was collected, what it covers, and what it does not.

How the data is handled
Each page is generated from a validated snapshot. Source responses are kept with checksums, records are checked for expected counts, identifiers, and duplicates, and only a complete snapshot is published. If collection or validation fails, the last good pages stay online. Every topic also offers its full records as CSV and JSON downloads. The sources and methodology page explains each source, its license, and its limits.
