  We report the results of a survey applied to students and professionals in
the area of physics in Brazil, pursuing to draw a portrait of the composition
of this community in terms of the social markers age, race, ethnicity,
geographical origin, sex, gender, sexual orientation, and disabilities. The
main goal was to quantify the representativeness of different groups in the
community and to detect motivations and difficulties encountered by each group
throughout their studies and career. This survey was open to the members of the
Brazilian Physics Society (SBF) from July to September 2018.
  Our outcomes reveal that (i) the Brazilian physicists community is poorly
diverse even in comparison with the population composition, (ii) the main
obstacle to pursue the career is socioeconomic vulnerability and (iii)
harassment is high in our society, being more pronounced among women.
  We hope that these results will be useful to scientific and educational
institutions to develop different strategies and policies to change this
current situation.
