Sport, since the late 19th century, has been and remains one of the most continuous and enduring human activities. It is also known as a cultural practice mainly dominated by men. The objective of this article, based on a quantitative analysis of cultural practices in Luxembourg, is to question interactions between sport, community-building and gender. It is hypothesized that sport in multicultural metropolises is a hobby generated not only by men but also by women who are involved in a cosmopolitan and secular society.
