  1. * Data for 1985 to 2002 based on birth cohort data. Data for 1965–69 and 1975–79 assumes that all live births < 500 g died in infancy (see text). Estimates of the number of live births < 500 g in the Northwest Territories in 1965–67 were extrapolated from data from the Northwest Territories in 1968–69 [12, 13].
