I think occupation is a confounder. Young people, whether they are students or workers, have to commute to school or their workplace every weekday, which guarantees a high frequency of contact. Meanwhile, for older people, many of them may have retired and do not have an occupation. This would mean they would tend to stay home on weekdays. This factor explains the difference in contact patterns outside of age.
