The present study addresses gender gaps in North American research productivity, which may be influenced by personal and family variables, as well as professional and work-related variables. The study was conducted as part of the "Changing Academic Profession (CAP) International Survey", conducted in 2007-08. Using articles as indicator of research productivity, we analyzed the gender gap in publication rates among full-time higher education faculty in our combined sample (Canada, Mexico, and the United States). This analysis has implications for higher education policy. In terms of research productivity, the relative productivity rates of male and female academics have been a policy priority for many years to increase the cumulative rates of research activity. We found that the variables related to research intensity varied by country, providing a more nuanced understanding of the gender gap between male and female faculty. (Contains 2 tables and 1 note.)
