Topics that are at the intersection of immigration and health are often connected to health disparity. Health disparities are often the manifestations of inequalities in healthcare access, treatment and diagnosis in vulnerable groups distinguished by race, ethnicity and nativity. Several indicators for health inequity are disability, uninsurance, chronic disease prevalence, mental health status and mortality and life expectancy.
The pace of immigration to the United States in recent decades has important implications on the demographics. The Hispanic population increased almost 4-fold since 1970 to 16.7% (2011), while the Asian/Pacific Islander population swelled 5-fold to 5.8% of total population. The American Community Survey (2013) found that 13% of total population are immigrants - with over 80% from Latin America and Asia. Mexicans is the largest immigrant population although the rate of increase is highest for Asian and Latin American countries.
