This study presents new aspects of the health expectancies of elderly Turkish migrants living in Germany relative to the health expectancies of the German host population. In this study, we pursue two objectives: first, we seek to compare the differences in the health expectancies of Germans and Turkish migrants; and, second, we seek to examine the factors which could affect functional limitations in the two groups. Our analyses are based on population data from the German Office for National Statistics and the Central Register of Foreigners, as well as individual-level data from the German Generations and Gender Survey 2005/2006. We use the measurement of health expectancy to highlight health inequalities between Germans and Turkish migrants living in Germany, and we employ the decomposition method to explore the impact of mortality and disability on differences in health expectancy. In addition, we apply a logistic regression model to detect variations in the factors that influence limitations in daily activities. We analyze this issue in separate samples for (a) Turkish migrants living in Germany and (b) Germans. The results on health expectancy show that there are significant differences by sex and nationality in the proportion of the remaining life expectancy spent in good and in bad health. Within the Turkish migrant population, women in particular show greater advantages in life expectancy, but also greater disadvantages in health relative to women in the German population.
