If the population growth in a municipality is calculated, municipal redivisions are taken into account. The municipal redivision of 1 January 2014 is extrapolated to the past and population growth is recalculated.
The municipality of Rozenburg, for example, was incorporated in Rotterdam on 18 March 2010. With respect to the population growth in Rotterdam, Rozenburg and Rotterdam are considered as one municipality during the entire period.
If municipal redivisions are not taken into account, the share in the population growth of the thirty largest municipalities is 93 percent.
