My guest today is the journalist and editor Ruby Warrington, author of the new book 'Women Without Kids: The Revolutionary Rise of an Unsung Sisterhood.' We spoke about why women are increasingly unlikely to have children, the grey area between voluntary and involuntary childlessness, and why we generally pay so much less attention to men who don't have children.

In the extended version of the episode we also spoke about the political and economic consequences of falling birth rates.
