The atlas shows 148 factories (fabriki and zavody) spread across 25 provinces. The distribution is far from uniform: 50 factories are located in Perm alone.
If you go through this layer in detail (either on the Imperiia Map or in Dataverse) you will notice that the "placenames" are, in most cases, no such thing: they are instead descriptions of the kind of factory at a given location. [Translations to come in the next iteration of the data.]
