This research note presents an index of interparty competition which satisfies four criteria: (1) it is a continuous variable; (2) it is a ratio scale; (3) it is linear with the concept of perceived competition, and (4) it may be generated from any array of two‐party data. It is maintained that these criteria establish the minimum conditions for precision measurement of political phenomena and that no other index of interparty competition accomplishes this.
