Fig. 7

The positive entries of the adjacency matrix A are shown in the figure, where a positive value represents how relatively far the labour flow between those two industries are from the random expectation, that is, more job switches than expected. The metric μ(G) reveals, for each sector G, how many times more likely is it to observe job switches within the sector relative to overall connectivity. For instance, μ(Social Services)=7.9 means that workers are nearly 8 times more likely to switch between different social service industries than if edges were allocated at random. For off-diagonal blocks, the shading corresponds to μ(G,G^′) for sector pairs G and G^′. We observe, for example, that switches between construction and mining and oil industries are denser than average connectivity in the network
