Length of stay and mental health of the immigrant population in Spain: evidence of the healthy immigrant effect

This article analyses the relationship between how long immigrant populations reside in the country of destination and the state of their mental health. The empirical approach to this relationship relies on data from the Spanish National Health Survey 2011–2012. The results confirm a Healthy Immigrant Effect that tends to decline in accordance with how long the immigrant stays. Immigrants who have been residing for less than 10 years in Spain have better mental health than the national population as a whole. It is important to study health disparities among the foreign population and how these evolve to ensure that it has access to health services and that its health care needs are met.
