Here in the United States, a new study has revealed there are still wide gaps in mortality rates between African-Americans and other groups. An African-American man living in a high-crime city can expect to live 21 fewer years than a woman of Asian descent in the United States. The man’s life expectancy, in fact, is closer to that of people living in West Africa than it is to the average white American. According to the Washington Post, the study found that the United States is pocked by places where millions of adults face a risk of premature death like that in Angola, Mexico and Nigeria. The study found Asian women to have the longest life expectancy — just over 87 years. African-American men living in urban areas have the shortest — just under 67 years.
