=== Purpose ===
As Wikidata Product Managers, we would like to understand how different segments of Wikidata's data developed over time, so we can inform our projections.
=== Scope ===
* How did the number of Items of the following types develop over time?
** A) Items that contain a sitelink to one of the Wikimedia projects (e.g. about a notable person)
** B) Items that are needed to build A (used in Item A in a statement or reference, e.g. the non-notable father of that notable person)
** C) All other Items
=== Desired output ===
* Monthly stats of the number of Items in category A, B and C
Acceptance criteria
[] Current numbers for A, B and C to verify the approach
[] Historic weekly data for A, B, and C (for all snapshots that are available)
[] Weekly data process to capture new data
[] Public output of data in the form of a table (and ideally diagram)
