Parameter	Metrics values
Parameter	Mekelle	Gondar	Hawassa	Full network
Diameter	2	5	6	6
Average shortest path length	1.36	2.1	2.1	1.96
Density	0.01	0.013	0.012	0.004
Reciprocity	0.027	0.018	0	0.014
Assortativity (based on degree)	-0.04	-0.32	-0.01	-0.17
Global clustering coefficient (CC)	0.15	0.18	0.07	0.13
Modularity^a	0.68	0.49	0.60	0.72
Components (GWCC)	33	18	15	63
Community (based on greedy optimization)	38	24	22	73
Centralization (by degree)	0.05	0.19	0.05	0.06

^aModularity value near to 0 indicates that the network considered is close to a random one (barring fluctuations), while a value near to 1 indicates strong community structure
