The United States has a multi-member constituency system for the Senate where each State elects 2 members, leading to 100 members in total, and one-member constituencies for the House of Representatives, each state being allocated at least one seat . Examples were already given of countries combining a proportional system in a nationwide constituency with a plurality system in one-member constituencies (Republic of Moldova, Russian Federation, Ukraine) or another combination of one and multi-member constituencies (Germany).
