Little is known about where physical activity (PA) occurs, or whether different demographic groups accumulate PA in different locations. ⋯ A large proportion of MVPA time is spent at "near" locations, corresponding to the home neighborhood studied in previous PA research. "Away" locations also host time spent in MVPA and should be the focus of future research.
