This research examined the health care related issues of the American seniors retiring in Mexico. Data for this study were collected through in-person questionnaire surveys and case studies. Findings of this study indicate that US seniors retiring in Mexico are predominantly non-Hispanic whites, married, and more likely to be college graduates. This study challenges the general perception that US seniors move to foreign countries is "amenity-led." The case studies clearly show that many US seniors move there because they are afraid that with reduced income and increased health care needs they would not be able to maintain the same lifestyle after retirement in the US. Climate and the slower pace of life are two other big attractions for seniors' to move to Mexico. A major finding of this study is age, gender, education, use of Medicare for medical care coverage, and chronic medical condition are significant predictors of US seniors' health behavior and health outcomes in Mexico. The policy implications of the findings have been discussed.
