Live births by time of occurrence are used in the calculation of vital statistics.
Deaths (excluding foetal deaths) by time of occurrence are used in the calculation of vital statistics.
Net movement refers to (i) net flow of Hong Kong Permanent Residents and Hong Kong Non-permanent Residents into the Hong Kong Resident Population; and (ii) net change of persons from visitor status to Hong Kong Permanent/Non-permanent Resident status.
Births and deaths data: Under legislation, births and deaths occurred in the territory are required to be registered at the Births and Deaths Registries of the Immigration Department within the specified period of time.
Net movement: the Immigration Department is responsible for recording information on passengers arriving in, or departing from, Hong Kong. A “Record Linkage” approach is adopted whereby large volumes of (anonymized) individual passenger movement records are linked and then tabulated for the compilation of net movement data in respect of Hong Kong Permanent Residents. As regards Hong Kong Non-permanent Residents, balance of arrivals and departures is used to estimate their net movement. Administrative data are used to calculate the number of persons changing status between visitor and Hong Kong Permanent Resident/Hong Kong Non-permanent Resident. This enables the computation of “resident population” estimates at any reference time-point.
Revision of provisional figures is due to the availability of information on the amount of time of stay in Hong Kong of residents during the six months after the reference time-point. The discrepancy between the provisional figures and revised figures is generally small.
