Extended Data Figure 10: Differences in country level daily steps are not explained by differences in estimated wear time.
From: Large-scale physical activity data reveal worldwide activity inequality
Users have an average span of 14.0 h between the first and last recorded step, our proxy for daily wear time (Methods). While on an individual level, longer estimated wear time is associated with more daily steps (r = 0.427, P < 10−10), on a country level, there is no significant association between wear time and daily steps (r = −0.086, P = 0.57). The line shows the linear fit using the 46 countries with at least 1,000 users. This suggests that differences in recorded steps between countries are due to actual differences in physical activity behaviour and are not explained by differences in wear time.
