[...] TOTAL FERTILITY RATE The total fertility rate is the sum of the age-specific fertility rates, usually 5-year rates, for women of reproductive age (15 to 44 years of age) during a specified time period, and represents the average number of children that would be born per woman if all women lived to the end of their childbearing years and bore children at the age-specific rates for that year. [...] SMALL-FOR-GESTATIONAL-AGE RATE AND LARGE-FOR-GESTATIONAL-AGE RATE The small-for-gestational-age (SGA) rate is defined as the number of live births whose birth weight is below the 10th percentile while the large-for-gestational-age (LGA) rate is defined as the number of live births whose birth weight is above the 90th percentile of the sex-specific birth weight for gestational age1. [...] In this report, the age-standardized rate is calculated by using the direct method, multiplying the age-specific mortality rates of the Canadian population by the First Nations population of the same age groups to yield expected numbers of deaths. [...] The age-standardized rate is calculated by using the direct method, multiplying the age-specific PYLL of the general population by the First Nations population of the same age groups to yield expected numbers of deaths.
