# Contact One address, read by the people who build the dataset: [hello@m2index.com](mailto:hello@m2index.com). ## Found a wrong number Send the page URL and what the source says. Every confirmed error becomes a dated entry in the [corrections log](/corrections/) — we publish our own mistakes rather than editing them away. If our figure disagrees with the primary source on the same observation date, that is a bug and we want it. ## Using the data The full dataset is a [single CSV](/data/broad-money.csv), free, no registration and no email gate, licensed [CC BY 4.0](https://creativecommons.org/licenses/by/4.0/). Attribution: "M2 Index, m2index.com", plus the observation date of the figure you quote. Journalists and researchers: if you need a cut we do not publish — a longer history, a specific country set — ask; the raw series are already there. ## What we cannot answer We publish measurements, not advice. We do not forecast money supply, recommend investments, or interpret what a number means for a portfolio. Questions about method — how a rate is windowed, why a series carries a break — are answered in the [methodology](/methodology/) and by email.
