It is well established that urban form can encourage or hinder daily walking activity. Consequently, urban form has a direct impact on both spatial accessibility and the ability of achieving daily physical activity recommendations. However, the relationship between urban form and walking patterns may present relevant differences among different population subgroups, for instance in terms of gender. In order to analyse how the relationship between urban form and daily walking time might be modulated by gender, the present study aims to explore walking patterns of men and women living in different neighbourhood types in Barcelona Metropolitan Region (Spain). For this purpose, the study uses data extracted from a smartphone tracking app among a rather specific population group: young adults who commute daily to the same destination. The findings show that compact urban forms promote gender equality. The study especially sheds light on the disadvantaged position of young women living in small towns and suburbs, who walk much less than other women and any men.
