In the next 15 years, America’s senior population will grow by 53 percent. People are living longer lives than ever before. Unfortunately, while we are living longer lives, we are seeing poorer health among people aging into their senior years. By looking holistically at key measures related to seniors’ lifestyles, social supports, environment, clinical care and health care outcomes, we get a comprehensive picture of senior health that reflects the unique challenges of each state. Based on a rigorous review of 34 measures, the 2013 America’s Health Rankings Senior Report finds Minnesota is the leading state for senior health and Mississippi ranks last for senior health.
