This study explored the gender and age distributions of health care personnel in Taiwan at present and in the future. Data from the Ministry of Health and Welfare for the 2014–2021 period were retrieved from a database containing the registration information of health care personnel. This study discovered that among 16 types of health care personnel, nurses and nutritionists had the highest and second highest proportions of women, respectively (nurses, 96.17%; nutritionists, 90.57%), whereas traditional Chinese medicine (TCM) physicians, dentists, and physicians had the lowest, second lowest, and third lowest proportions of women, respectively (TCM physicians, 32.77%; dentists, 30.09%; physicians, 21.16%). From 2014 to 2021, the gender distribution for these five types of health care personnel gradually became more balanced. However, the time required to achieve gender parity (indicated by the male-to-female ratio) was estimated to be approximately 184.5 years for nurses and approximately 30–40 years for physicians. These numbers of year can serve as references on the state of gender equality in health care professional fields; they also remind families, schools, and the societies to strengthen the gender freedom and equality for male and female to devote in health care professionals.
