Software Engineering Conferences have established themselves over the years as a pivotal venue for presenting research studies in the field of SE. The task assigned to Program Committee members is notably challenging, involving the analysis, review, and acceptance of submitted papers for inclusion in the conference. Recognizing the value brought by diverse perspectives, the formation of a diverse Program Committee is commonly recommended for each Software Engineering conference. This paper undertakes an analysis of the diversity among Program Committee members in three of the most prominent Software Engineering conferences: ASE, ESEC, and ICSE, spanning between years 2019 to 2023. The analysis of diversity includes factors such as gender, geography, seniority, continuity in participation, and affiliation with industry/academia. The data analysis reveals variations in representation across different communities, with some consistently showing lower levels of representation. However, it is noteworthy that in certain scenarios, measures implemented to enhance diversity demonstrate a positive impact.
