Degressive proportionality is an approach to the allocation (between regions, states or other subdivisions) of seats in a legislature or other decision-making body. Degressive proportionality means that while the subdivisions do not each elect an equal number of members, smaller subdivisions are allocated more seats than would be allocated strictly in proportion to their population. The seats-to-votes ratio decreases for larger subdivisions.
