Notes

In this interactive dashboard, the birth data come from the Canadian Vital Statistics - Birth database (CVSB) and from the Quarterly Demographic Estimates. The fertility indicators are calculated using the data above and the Annual Demographic Estimates: Canada, Provinces and Territories. For more information on the birth and fertility indicators used to generate this dashboard, please see the documentation provided in the source tables listed in the Data section above.

The geographic distribution of live births in this table is based on the mother's usual place of residence.

Includes births to mothers who are residents of Canada, with unknown province or territory of residence. Births for which the province of residence is unknown, and not imputed with the place of occurrence, were prorated using the observed distribution.

The population estimates used are the most recent available at the time of dissemination, adjusted for census net undercoverage (CNU) and incompletely enumerated Indian reserves (IEIR).

Fertility is innately linked to biological processes. The various indicators presented in this visualization utilize demographic estimates by age and sex at birth. For ease of reading, the terms “woman” and “women” are used throughout.

Definitions

Age-specific fertility rate
Age-specific fertility rate is the number of live births per 1,000 women in a specific age group. The calculation consists of dividing the number of births to mothers by the population of women, for each unique age, and then multiplying by 1,000. Five-year age groups were used in these tabulations (ranging from 15 to 19 years to 45 to 49 years).
Annual change in births
The annual change in births is the difference between the number of births in a given year and the number of births in the previous year. The annual percentage change consists of dividing the annual difference by the number of births in the previous year and then multiplying by 100.
Average age of childbearing
The average age of mothers at childbirth is the mean age of mothers at the birth of their child for a given year. Average age is calculated by summing the single-age fertility rates that have been multiplied by the mid-year age, and then dividing this sum by the total fertility rate. Births for which the age of the mother is unknown were prorated using the observed distribution.
Mother’s age
Mother's age on last birthday before delivery.
Total fertility rate
Total fertility rate is an estimate of the average number of live births a woman can be expected to have in her reproductive life, based on the age-specific fertility rates of a given year. The total fertility rate is the sum of the age-specific fertility rates divided by 1,000.
