# Table 1 Definitions of network terminology and metrics used in this study

Poultry sources |
1) “Farm upazila”: An upazila (third administrative division) in which farms supplied a trader in a surveyed LBM. Exact names and locations of farms were unknown, they were therefore grouped into so-called “farm upazilas”. 2) A LBM (each LBM was an independent location). |

Network node | A surveyed LBMs, a “farm upazila” or a non-surveyed LBM. |

Network arc | Link between 2 nodes, weighted with the number of poultry traded between the considered sources and destinations. |

Giant weak Component (GWC) | The largest subset of nodes in which all the nodes were connected, regardless of the direction of the arcs. |

Giant Strong Component (GSC) | The largest subset of nodes in which all the nodes were connected, accounting for the direction of the arcs. |

Connectedness of the network | The proportion of nodes included in the GWC [30]. |

Normalised betweenness-centrality | The proportion of shortest paths (i.e. geodesic distances) on which a given node lies. |

Geodesic distances | Shortest path between two nodes, with the distance being calculated as the sum of the inverse of the arc strengths [64]. |

Input domain | Proportion of the nodes that can reach a node following network arcs. |

Output domain | Proportion of the nodes that can be reached by a node following network arcs. |
