With more than 50,000 members, American Mensa is the largest national Mensa operating under the auspices of Mensa International, Ltd. There are currently more than 140,000 members worldwide, and an estimated 6 million Americans are eligible for Mensa membership.

Mensa members range in age from 2 to 106. They include engineers, homemakers, teachers, actors, athletes, students, and CEOs, and they share only one trait — high intelligence. To qualify for Mensa, they scored in the top 2 percent of the general population on an accepted standardized intelligence test.

Members have the opportunity to meet other smart people at local, regional, and national levels. They attend entertaining, intellectually stimulating events and exchange ideas with others through a variety of publications and online communities. They also work to help others through community-oriented activities and by working with the Mensa Foundation. And you can take advantage of our variety of member benefits and services.
