Note that the registry for this is not central but managed by the towns instead. So it's very decentralized and data in this aggregated form doesn't exist. An often used trick by towns is to pretend some person didn't move away from the town, thus not decreasing the number of people who live there, thus increasing the number of various funds that are paid based on how many citizens the town has. So those registries often aren't 100% accurate.
