Physician supply

Physicians are doctors who help keep us healthy. The number of doctors in the world is called the physician supply. If we have too few doctors, people can't get the medical help they need and will have to wait a long time to see a doctor. But if we have too many doctors, some might not have enough patients and have to close their practice. So it's important to make sure there's the right amount of physicians. To do that, governments and organizations monitor the number of doctors and sometimes offer special programs to help people become doctors.
