Goal:To evaluate the sociodemographic profile of women undergoing cesarean section in Minas Gerais from 2010 to 2020. Methods: Ecological time series study of cesarean section rates, correlating them with sociodemographic variables and Robson's classification. Data were collected at SINASC, from DATASUS. Results: A total of 57.1% of births in Minas Gerais in the last decade were by cesarean section, with the highest rates among women with higher education and over 30 years of age, those between 28 and 36 weeks of gestation, and in parturients in group 5 of Robson, composed of women with a single fetus, at term and with a previous cesarean section. The impact of cesarean section rates is not just financial, it also brings risks to the health of the mother and baby. Conclusion: Cesarean sections are prevalent in women over 30 years of age, with a high level of education, previous cesarean section or nulliparous women who have never gone into labor. Vaginal birth rates are highest in full-term and extremely premature fetuses. The high rates contradict international recommendations and highlight the need to encourage vaginal birth in all pregnant women.
