Table 2.
Sub-Population Sizes Affect the Impact of Heterogeneity in Activity and Preferential Mixing on ℜ0. When sub-population sizes are unequal, as in scenario C, the larger dominates, but when they are equal, as in scenario D, heterogeneity and preferential mixing have greater impact. Other parameters: N = 1000, a1 = 5 and a2 = 10 (the village and city if N1 ≪ N2).
