Starting in 1966 (in the wake of "Reynolds v. Sims," a US Supreme Court case establishing the principle of one man, one vote), members of the North Carolina State House were required to be elected from districts defined on the basis of roughly equal population, rather than from geographic counties. The county basis had resulted in a longstanding rural bias in the legislature. The new urban populations, including minorities and immigrants, were historically underrepresented in terms of legislative seats and funding, although the state's demographics and population had become increasingly urbanized. The court's ruling required changes also in other states with similar practices. The changes allowed full representation for the first time from some urban and more densely settled areas. It also meant that counties with low populations lost the chance to elect a resident member to the legislature for the first time in state history.
