The boundaries and names of census subdivisions (municipalities) can change from one census to the next. In order to facilitate data comparisons between censuses, the data for the 2001 census subdivisions (municipalities) have been adjusted to reflect as closely as possible the 2006 boundaries of these areas.
For some census subdivisions (municipalities), it was not possible to reflect the 2006 boundaries. Therefore, it was not possible to calculate the 2001 to 2006 percentage change or data pertaining to 2001. In addition, some census subdivisions (municipalities) were incompletely enumerated in 2001 or were suppressed. Therefore, it was not possible to calculate the 2001 to 2006 percentage change or data pertaining to 2001.
