On the measurement of naturalization

This paper proposes a new way of measuring naturalization, which takes into account both emigration and death. I argue that the new method corrects for underestimation and thus provides a more accurate measure of the concept. Using data from six groups of the 1973 immigrant cohort and multiple-decrement life table techniques, I estimated and compared naturalization measures derived from new and old methods. The results show that failure to control for emigration has a significant effect on the measurement of naturalization, particularly if an immigrant group has relatively high rate of emigration. Some further substantive implications of this new method are also explored.
