Health geographers have engaged in research associated with immigrant health and the healthy immigrant effect through various themes common to health geography, including health-care access and delivery, social models of health and health care, and environment and health. This chapter explores issues associated with the health of immigrants and refugees, including a discussion of the healthy immigrant effect. It provides insights into the evolving research agenda and key questions that health geographers should consider to advance the research agenda. There are many opportunities for health geographers to engage with scholars from other disciplines, including economics, sociology and anthropology, and draw upon different frameworks and perspectives to advance the immigrant health research agenda. Research agenda could, for example, pursue questions related to the nuances around the health of refugees, such as the implications associated with the reason for movement, and the implications associated with the route, transit time to a host country and settlement in a destination country.
