* Figures regarding the number of connections have been adjusted retrospectively - from 2020 - to be in line with the numbers in the Central Connection Register (Centraal AansluitRegister = C-AR).
* This figure was restated in 2023: due to a miscalculation, some of the ‘switchers’ in 2022 were not included.
