  The Brazilian Symposium on Software Engineering (SBES) is one of the most
important Latin American Software Engineering conferences. It was first held in
1987, and in 2019 marks its 33rd edition. Over these years, many researchers
have participated in SBES, attending the conference, submitting, and reviewing
papers. The researchers who participate in the Program Committee (PC) and
perform the reviewers' role are fundamentally important to SBES, since their
evaluations (e.g., deciding whether a paper is accepted or not) have the
potential of drawing what SBES is now. Knowing that diversity is an important
aspect of any group work, we wanted to understand diversity in the SBES PC
community. We investigated a number of characteristics of SBES PC members,
including their gender and geographic location. We also analyzed the turnover
and renovation of the committee. Among the findings, we observed that although
the number of participants in the SBES PC has increased over the years, most of
them are men (~80%) and from the Southeast and Northeast of Brazil, with very
few members from the North region. We also observed that there is a small
turnover: during the 2010 decade, only 11% of new members were added to the PC.
Finally, we investigated the participation of the PC members publishing papers
at SBES. We observed that only 24% of the papers accepted to SBES were authored
by members who were not committee members of the respective year. Moreover,
committee members usually do not collaborate among themselves: a significant
number of the papers are authored by the PC members and students. This paper
may contribute to the SBES community, in particular, its special interest
group, in understanding the needs and challenges of the PC's participants.
