Table 4 shows that centrality is more concentrated in this product group than in the other two.
Using out degree centrality as a metric (column 1), North America exports to, on average, over
six times as many countries as does Sub-Saharan Africa. Centrality is again approximately
increasing in per capita income. Similar insights are apparent from a consideration of
eigenvector centrality (column 2), with the dispersion of scores in this case higher than in the
other two sectors, which indicates that world exports of fish products are more geographically
concentrated than in the other two product groups.
