The article is concerned with the accuracy and reliability of net migration estimates. There may be no final resolution of a single best set of provincial net migration estimates, however, sources of errors and their approximate magnitudes should be more widely appreciated than they are. The available estimates of regional migration in Canada reflect almost the full variety of methods of estimation that have been developed elsewhere and discussed in the literature. One of the more interesting developments in literature has been the realization that the Census Survival Ratio (CSR) method, developed to produce historical estimates of net migration for periods before national vital registration, had the added virtue of greater reliability than Vital Statistics or Life Table Survival Ratio (LTR) Methods estimates. The chief advantage of CSR estimates is that, if expressed as rates of migration with an appropriately selected base population, they tend to cancel out census enumeration errors and thereby produce more reliable estimates of net migration. On the other hand. LTR methods, which more accurately account for deaths tend to misstate net migration by the amount of net census error.
