The collection

Maintained indices and trackers

These datasets are maintained as long-running public goods, distinct from the Institute’s one-off reports and papers. Each is versioned, updated on a fixed cadence, built from named sources, and released under a CC BY 4.0 licence with a documented methodology and codebook. For a single study rather than a maintained series, see the publications library.
