ANNEXED NOTE

1. Technical Notes and Definitions

The table provides mid-year intercensal estimates of Bahrain’s total resident population (nationals and non-nationals)
Reference period: 1991: unknown; April 7th 2001, April 27th 2010.
Implementation method: the Censuses are carried out according to de jure methodology, i.e. counting persons using their usual place of residence irrespective of where are they at census times
Population of reference: all individuals (nationals and non-nationals) present within the State’s borders during time of reference.
Nationality of the person is defined by the passport used to enter the country. A Non-Bahrainis is considered as such depending on the passport used to enter the country (or obtain the visa)

It has to be noticed that the mid-year estimate for 2010 gives a figure lower than that of the census (April 27, 2010)
