Number of live births includes births with
unknown birth weight.
Age of mother attained at the last birthday
preceding delivery.
For confidentiality reasons, live births to
mothers aged 50 and over are included in the category "Age of mother,
not stated." Where information is unavailable on the birth mother of children
who are adopted, these records are included in the category "Age of mother,
not stated."
Partway through 2003, Alberta Registries
amended their Registration of Birth form in such a way that Statistics Canada
can no longer determine the legal marital status of those persons in common-law
marriages.
