This study addresses for the first time in Greece the issue of levels and patterns of mortality among natives and immigrants, using vital statistics and census data by citizenship. Life tables are constructed for the two most numerous communities, Albanians and Bulgarians as well as for all immigrant populations combined; standardized mortality ratios are estimated for smaller migrant groups. Albanian males have a slight mortality advantage compared to natives; all other groups experience higher mortality. Some support for the “selectivity of migrants” hypothesis is provided as immigrants in several cases have significantly lower mortality compared to their countries of origin. Implications for public health policy in Greece are discussed.
