Mercators

Needs by category

Consumption is per residence at the base rate (Low setting, ×1). Multiply by 1.25, 1.5 or 1.75 for the Medium, High or Very High consumption settings. Supply value is what the need adds toward its category's upgrade threshold. "Residences per building" uses one producer at 100% productivity.
