The changing pattern of fertility differences among ethnic groups in Canada during the period 1926–71 is studied. Two specific questions are addressed. (1) Do ethnic groups assimilate the fertility patterns of the general Canadian population over time, i.e. are the fertility differences disappearing? (2) Is the extent of assimilation in fertility greater in urban than in rural areas? The indirectly standardized general fertility rates, calculated by using the ethnic age distribution data from the censuses of 1931 to 1971, indicate a tendency for the population to become more homogeneous during times of increasing fertility, thus supporting the assimilative possibilities, whereas in times of declining fertility there is a tendency for the population to become more heterogeneous. The data also seem to support weaker assimilatory tendencies in rural areas than in urban areas during only the most recent period, 1966–71, and not in earlier periods.
