The organization spread through the United States, Canada and related territories, Hawaii and the Philippines. In 1900 it had a membership of 20,000 centered in California. It was strongly encouraged by the Archbishop of San Francisco, Patrick William Riordan and received the approbation of Pope Leo XIII and Pope Pius X, as well as the approval of various members of the Catholic hierarchy in the territories that it operated in
The Young Men's Institute (YMI) is still active in a number of Catholic parishes in California, Hawaii and Indiana. Membership is at approximately 2000 men, who are recognized as "brothers". YMI membership is now divided into four categories: benefit members (18 to 45), associate members (those over 45), junior members (those ages 13-23 attending school full-time) and Honorary members (reserved for clergy). Annual dues are nominal for benefit and social members and free for junior and honorary members.
The YMI runs a nominal death benefit program for its benefit members, a scholarship program via an essay contest, and has a national convention. In addition, the YMI hosts various sporting tournaments (i.e. bowling, golf and bocce ball), as well as an annual Red & White Mass (celebrating its anniversary) each March and a pasta bingo dinner each November. Through foundations under the YMI banner, the organization provides tuition assistance for the children of members that become deceased, as well as scholarships for seminarians to ease their path to the priesthood..
