With an increasing percentage of the global population living in cities and the concurrent decrease in physical activity in daily life, public health issues for urban development have arisen. This study responds to that trend by presenting an approach to measure city-wide physical activity levels. Comparing of city indices for active sports and the active transportation shows differences between subject cities and activity level of age groups in sports as well as walking and cycling. Therefore, our study lends itself to implications for urban development towards creating a healthier city.
