Correlations between social and mobility fluxes. Correlations between $T_{i\to j}^S(r\prime )$ and $T_{i\to j}^M(r\prime )$ for location pairs (gray dots) separated by a distance of (A) $r\prime =1e3$, (B) $r\prime =1e4$, (C) $r\prime =5e5$, (D) $r\prime =1e6$, and (E) $r\prime =2e6$. We find all curves collapse into a straight line when $\overline{T^S}$ is rescaled by $r^{\prime {\delta }_{r\prime }}$ for (F) $D1$, (G) $D2$, and (H) $D3$.
