Data Sources and Methodology

Current estimates of the population are based on the 2001 population census and annual estimates of births and deaths obtained from the Registrar General’s Department (RGD). Estimates migration are calculated based on statistics produced by the major receiving countries, supplemented by data extracted from the Embarkation/Disembarkation cards made available by the Passport Immigration and Citizenship Agency (PICA).

The births and deaths represent events occurring in the year and registered up to 12 months after, adjusted by STATIN for under coverage. Details of the adjustment process are presented in the annual Demographic Statistics reports.

All data are considered provisional and subject to change as revised births, deaths and migration statistics become available.
