Turnover of an individual's closest associates. Bars show the fraction of individuals that retain a given number of associates in their top-five (see Methods and Results). Value zero in the x-axis implies that the identities of an individual's top-five associates have completely changed over five seasons; value 5 implies that her top-five associates have not changed over this period. For example, approximately 20% of individuals retained two associates over all five seasons.
