Fig 1. Analysis of methods M0 and M1.

A-B: Demographic structures for different years and the respective non-reciprocal matrices $N{R}_{i,j}^{\prime }$ for Poland and Zimbabwe respective using M0. C: Evolution of the total fraction of non-reciprocal contacts for M0 in the 16 geographic settings analyzed in this study. D-E: $log2\left(\frac{{\Gamma }_{i,j}^{\prime }}{{\Gamma }_{i,j}}\right)$ for Poland and Zimbabwe respectively, in four different years (10/20 years before/after the measurement of the contact patterns) for M1. The original data corresponds to 2005 for Poland and 2013 for Zimbabwe.
