Table 1. State variables of households represented in the DECUMA model. Variables are grouped into classes for clarity. These variables are assigned initial values only. Livestock populations, the cashbox, assets, and debts may change during a simulation. Milk income depends on the number of lactating cattle in the household herd. Other attributes of the household do not change during a simulation.
