Age-based mixing matrices for participants’ total number of encounters with listed individuals. Values are the mean of participants’ total (weighted) number of encounters with listed individuals by age of participant and contact for male participants (left panel), and female participants (right panel). 95 % confidence intervals are shown in parentheses. Darker shading indicates larger values. Age-based assortative mixing is evident for both genders. Women notably have more numerous contacts with children less than 15 years old. Males 18–29 have the most numerous contacts within age groups. Raking weights are used to reduce the effects of sample bias
