Women tend to experience a substantial decline in their labour income after their first child is born, while men do not. Do such ‘child penalties’ also exist in the political arena? Using comprehensive administrative data from Norway, we find that women are less likely than men to secure elected office after their first child is born. The effects already manifest from the nomination stage, where mothers receive less favourable rankings on party lists relative to comparable fathers. This paper broadens our understanding of a fundamental social issue in political representation and demonstrates how motherhood even affects positively selected women.
