West virginia constitution
Article VI: the legislature
Section 7

After every census the delegates shall be apportioned as follows: The ratio of representation for the House of Delegates shall be ascertained by dividing the whole population of the state by the number of which the House is to consist and rejecting the fraction of a unit, if any, resulting from such division. Dividing the population of every delegate district, and of every county not included in a delegate district, by the ratio thus ascertained, there shall be assigned to each a number of delegates equal to the quotient obtained by this division, excluding the fractional remainder. The additional delegates necessary to make up the number of which the House is to consist, shall then be assigned to those delegate districts, and counties not included in a delegate district, which would otherwise have the largest fractions unrepresented; but every delegate district and county not included in a delegate district, shall be entitled to at least one delegate.
