title: [The concept of open stable population:  an application to the study of changes in population structure].
abstract: "The open stable population model is an extension of the stable population model.  It is based upon a new immigration index.  The model is used to study the impact of demographic phenomena on the population's structure by age and place of birth.  For a given increase in the rate of growth, a fertility increase has more impact on the rejuvenation of the age structure than an immigration increase.  With an average of 1.75 children per woman, the minimum immigration level required to avoid a decrease in population would result in a percentage of foreign-born similar to the maximum observed in any developed country...."  The geographical focus is on developed countries, particularly Canada. (SUMMARY IN ENG AND SPA)
