There is ample evidence that women know less about politics than men. Recent work has shown that parenthood affects political knowledge so that the gender gap is greater between parents than non-parents. However, little is known about when and how parenthood affects the way individuals acquire political information. We use an original five-wave longitudinal data collection of Swedish parents (N = 6,940) following expecting parents from early pregnancy until the child is two months (the Swedish Pregnancy Panel). Pregnant woman and their partners were recruited in a waiting area of a hospital that receives 96 percent of all pregnant women in the second largest city of Sweden, providing unique coverage of parents from different backgrounds. Participants were asked about political events, and we changed our measures every third week during 18 months and covered events relevant to the population. We provide a unique insight into how parental identity, time constraints, and pregnancy and childbirth-related complications affect women’s and men’s political knowledge. Preliminary results show that knowledge about political events decreases during this time of life, and we see a greater drop for fathers, closing the gender gap somewhat temporarily. For certain topics, most significantly for welfare topics, both mothers and fathers learn more. Furthermore, the hypothesized mechanisms are confirmed where a higher level of parental identity results in a larger gap. Time constraints is also partially confirmed, but mostly for women. We engage in a discussion about a lifelong process of socialization with adult experiences.
