Get registration statistics

Retrieve aggregated registration and termination statistics, broken down by time period, country and optionally by municipality.

Statistics are pre-computed from the full dataset and refreshed after each daily sync.

active_count is the running net total for that municipality — registrations minus terminations up to and including the period — i.e. the number of organizations on the register at the end of it. Organizations with no establishment date are not part of the series.

Each country is a separate series. Use countries=SK,CZ to retrieve both.
