Summary of data.

NOTE. NA, not applicable, as individuals may be resampled from round to round but partnerships are not; hence the number of individuals in each round also does not sum across all rounds.* Data on up to two recent partners was collected in rounds 1 and 2, and up to three for round 3. For consistency, the third reported partner was omitted for the calculated mean partners per individual and standard deviation for round 3, where one existed (n = 34 for men and n = 2 for women).
