Employment of medical assistants is projected to grow 18 percent from 2020 to 2030, much faster than the average for all occupations.  About 104,400 openings for medical assistants are projected each year, on average, over the decade. Many of those openings are expected to result from the need to replace workers who transfer to different occupations or exit the labor force, such as to retire.
