More than 57% of practicing Michigan doctors plan to retire by 2020. The Michigan population is forecast to grow by just 600,000 in the next 14 years, but by then the population over 65 will be nearly 500,000. The state has 30,000 licensed doctors, and that number is expected to remain constant for the foreseeable future. There are many reasons for the shortage, but the state's problems in attracting and keeping people in every field are the same for doctors. Wayne State is the state's largest medical school. It admitted 256 students in 2004, 270 in 2005 and expects a first-year class of 300 this year. But more medical students won't solve the problem if hospitals don't have the money and personnel to train the graduating medical students in residency programs.
