 In 1986, theorists Kyriakos Markides and Jeannine Coreil developed the idea of the Healthy Migrant theory that thought of migration to include an inherent selection process due to the physical and psychological demands of travel, searching for employment, and adjusting to new cultural norm.This paradox theorized that despite the social disadvantages of transitioning into a new country especially for ethnic minority groups, there is an inherent physical and psychological robustness in immigrants compared to populations in both their home country and the United States.Although the data that supported the Healthy Migrant theory converged on the idea that general immigrants arrived to the United States healthier than native-born Americans, the theory does not take into consideration the populations that immigrate to the United States for necessity, such as refugees, undocumented immigrants, or families looking for academic or financial opportunity.
