# Myrdal data — terms of use

This package is a **compilation** of demographic and migration statistics drawn
from the public sources named, series by series, in `PROVENANCE.csv`.

**The upstream sources keep their own terms.** Each series in `PROVENANCE.csv`
names the body that published it (World Bank WDI, the Maddison Project, Clio-Infra,
the World Inequality Database, the US Census Bureau, and the IRS Statistics of
Income division). Consult that body for the terms that apply to that series. No
term is asserted here on any upstream publisher's behalf.

**The compilation** — the series identifiers, the per-series files, the data
dictionary and the provenance record — is offered under **CC-BY-4.0**, as
declared in `CITATION.cff`. That grant covers this compilation only; it cannot
and does not re-license anyone else's underlying data.

It is a reconstruction: it can lag official revisions and can contain
reconstruction error, and it is not a substitute for the original source. For
authoritative figures, defer to the source named for that series.

**No warranty.** Provided as is.
