It deals with the study of the professional and educational profile of federal deputies from 1988 to 2022. In almost thirty-five years of existence, the Federal Constitution of 1988 allowed countless Brazilian men and women to participate in the electoral process and to occupy elective mandates, transforming the Chamber of Deputies into a body rich in heterogeneity and knowledge. From quantitative descriptive research, supported by information from the Open Data portal of the Chamber of Deputies and the Parliamentary Legislative Information System, it was possible to identify that most parliamentarians of the last nine legislatures (48th to 56th) have higher education, the predominance of males among the elected representatives and a profession, with the most common professions being lawyer, businessman, teacher, medic, and engineer.
