Social and economic inequality is detrimental to the health of any society. This is true when the society is diverse, multicultural, overpopulated and undergoing rapid but unequal economic growths, including immigrations issues such as undocumented immigrants. Anything undocumented cannot be measured but I think there can be estimative factors leading to predictions of the result. Secondly, most of the data could rely mostly on what is documented, such as documented Mexicans/Latinos and their life expectancy or health inequality. Increasing the racial and ethnic diversity of the health care workforce is essential for the adequate provision of culturally competent care to our nation’s growing minority societies. A diverse health care workforce will help to expand health care access for the underserved, improve research in deserted areas of societal need, and enrich the tarn of managers and policymakers to meet the needs of a diverse public.
