# Stats > Monthly totals for the people you invite: closed months only, final when published, rounded and designed so they don't identify a person. `GET /api/partner/v1/stats?month=YYYY-MM` (scope `stats:read`) answers one published cohort month. The cohort is the people who **signed up** in that month. - `invites`, `opened`, `signed_up` — exact. - `plan_created`, `practised`, `purchased` — that cohort's later steps, whenever they happened; for your whole partnership only. With `sub_partner_ref=…` the answer has the three exact counts only. A month is published once, on the 1st of the month after next, and never changes; an earlier month answers `422` "counts for this month are not published yet". After signed up, a cohort under 10 comes back as `"hidden"`; other counts are rounded to the nearest 5 (`"rounded": true`), or `"<5"`, or `"hidden"` when they could identify someone. The month is the only window parameter.
