Membership data on the organization is scarce. In his official report to the 1900 convention of the party, National Secretary-Treasurer Theodore Debs indicated that as of March 1, 1900, the dues-paying membership of the party was 4,536, participating in 226 active local branches. Of these, the younger Debs brother indicated that 985 members and 53 branches had been established during the previous 60 days, implying a significantly lower membership for the years 1898 and 1899. In the 1900 presidential election, Debs stood as the party's presidential candidate and received some 87,000 votes. This was considerably more than the established Socialist Labor Party.
