Flux distributions. Fat-tailed distributions of (A) social fluxes $T^S$ and (B) mobility fluxes $T^M$ for all three datasets. The fluxes $T_{i,j}^S$ (or $T_{i,j}^M$) are defined as the total number of communications (or jumps) between two locations i and j. The term fat-tailed refers to distributions $p\left(x\right)$ whose decay at large x is slower than exponential.
