This paper fills in a research gap in what concerns gender and academic rank at UK universities, where women are not far from reaching the 50% share of all academic and research staff, but not even close to reaching such a share at (full) professorial level. Using an ordered logit model and the results of a survey conducted in 2013 with 2270 responses from academics from all fields of knowledge at the 24 Russell Group universities, we find three consistent results. First, being a woman has a negative and significant association with academic rank, except for the case when parenthood is timed with career considerations in mind. Second, the percentage of time spent on teaching and teaching-related activities has a negative and statistically significant association with academic rank. This association is more pronounced in the case of women, who spend a higher percentage of their working time on teaching and teaching-related activities than men, as do those in lower academic ranks. Since women tend to be in lower ranks, the percentage of time spent on teaching and teaching-related activities may be considered both a cause and a result of the gender gap. Third, we find a positive and significant association between the number of children under the age of 18 years and the academic rank of both men and women, as long as babies were timed with career considerations in mind, and a non-significant association when they were not. A possible explanation for this is unlikely to be that children have a positive impact on academic rank, but rather that they arrived after a certain rank had been secured. We conclude with some policy recommendations to help reduce the gender gap.Sustainability 2019, 11, 3171 2 of 46 not limited to, respondent's year of birth, number of children, responsibility for household chores, academic degrees, number of publications, grants, percentage of working time spent on teaching and teaching-related activities, and main area of research. This is timely and relevant, given that the last empirical quantitative study to include UK-based academics of all fields of knowledge was conducted in the year 2000; the results of that study are reported in [3].We find some results in line with previous work conducted for other countries or for specific fields of knowledge and some novel ones. First, being a woman has a negative association with academic rank, even after controlling for year of birth (i.e., age), marital status, responsibility for household chores, area of research, timing of babies, number of children under the age of 18 years, holding a PhD or not, percentage of working time spent on teaching and teaching-related activities, and a number of research productivity variables. The only case where the variable gender is not significant is when only men and women who timed their children with career considerations in mind are included in the sample. Importantly, we also find that the percentage of time spent on teaching and teaching-related activities, which is higher for women than for men, is negati...
