Wyo. Const. art. 3, § 3: Legislative apportionment.

Each county shall constitute a senatorial and representative district; the senate and house of representatives shall be composed of members elected by the legal voters of the counties respectively, every two (2) years. They shall be apportioned among the said counties as nearly as may be according to the number of their inhabitants. Each county shall have at least one senator and one representative; but at no time shall the number of members of the house of representatives be less than twice nor greater than three times the number of members of the senate. The senate and house of representatives first elected in pursuance of this constitution shall consist of sixteen and thirty-three members respectively.
