Note. Age group (range, in years); number of people who could be included in the focal group (percentage of women, %f); number of scans with people in the focal group as agents (F-scans); number of slices in which those focal people were observed (Slices); number of other people whose data were collected in those same slices (Others); number of scans with these other people as agents (O-scans); Avg in location indicates in each slice involving a focal person, how many other people are present, on average, in the same precise location as the focal person.
