While Hispanics in the United States face persistent socioeconomic disadvantage,they generally experience lower mortality throughout the life course. This “Hispanic mortality paradox” is well documented in the demographic literature. Despite the importance of past research, less attention has been paid to the differential mortality experience of Hispanic subgroups in the United States. Understanding the heterogeneity in life expectancy by subgroup is critical for a complete understanding of the Hispanic mortality paradox. Yet data limitations have precluded a comprehensive study by country of origin for smaller sending countries. Using Social Security administrative mortality records, we find an overall mortality advantage for immigrants from20 countries in Central and South America. There is substantial variation by countryof origin, with migrants from disadvantaged countries showing the largest mortality advantage. Our results suggest selective in-migration is a key driver of the Hispanicmortality paradox and highlight the importance of studying the differential mortality experiences of Hispanic subgroups in the US.
