Concept


Supporters of unicameralism note the need to control government spending and the elimination of redundant work done by both chambers. Critics of unicameralism point out the double checks and balances that a bicameral system affords, forcing a greater level of consensus on legislative issues. A feature of unicameralism is that urban areas with large populations have more influence than sparsely populated rural ones. In many cases the only way to get sparsely populated regions on board a unified government is to implement a bicameral system (such as the early United States). Supporters say this is an advantage, as they see it provides better apportionment
