Based on survey data from the Worlds of Journalism Study (WJS-3), This chapter aims to explore the gender wage gap in Mexican journalism, paying special attention to the wage levels at which it is manifested, as well as the possible factors that determine it, both on the supply side (characteristics of human capital), and on the demand side of the market (characteristics of media organizations). Based on survey data from the Worlds of Journalism Study (WJS-3), the analysis confirms the existence of the gender wage gap among professional journalists. The shape of the distribution of journalists' salaries, in which women are overrepresented at the lowest levels and underrepresented at the highest levels, is congruent with the phenomena of the sticky floor and the glass ceiling, found in studies analyzing gender gaps in other contexts and industries. The largest wage gap was identified between journalists in part-time work schemes. Wage gaps between male and female journalists emerge regardless of the scope or ownership scheme of the media. The study also found gender segregation determined by the scope of media, as local media (which offer lower pay and worse working conditions) tend to a greater extent to have female workers.
