This Alberta Official Statistic describes the distribution of the immigrant population by age and sex in Alberta for 2011. Immigrants are persons who are, or have ever been, landed immigrants in Canada. A landed immigrant/permanent resident is a person who has been granted the right to live permanently in Canada by immigration authorities. Some immigrants have resided in Canada for a number of years, while others have arrived recently. Some immigrants are Canadian citizens, while others are not. Most immigrants are born outside Canada, but a small number are born in Canada. In the 2011 National Household Survey (NHS), 'Immigrants' includes immigrants who landed in Canada prior to May 10, 2011.
