===Membership demographics===
Membership in Narcotics Anonymous is voluntary; no attendance records are kept either for NA's own purposes or for others.<ref name="Sep" /> Because of this, it is sometimes difficult to provide interested parties with comprehensive information about NA membership. There are, however, some objective measures that can be shared based on data obtained from members attending one of NA world conventions; the diversity of membership, especially ethnic background, seems to be representative of the geographic location of the survey. The following demographic information was revealed in a survey returned by almost half of the 13,000 attendees at the 2003 NA World Convention held in [[San Diego]], [[California]]:
• Gender: 55% male, 45% female.
• Age: 3% 20 years old and under, 12% 21–30 years old, 31% 31–40 years old, 40% 41–50 years old, 13% over age 51, and 1% did not answer.
• Ethnicity: 51% Caucasian, 24% African-American, 14% Hispanic, and 11% other.
• Employment status: 72% employed full-time, 9% employed part-time, 7% unemployed, 3% retired, 3% homemakers, 5% students, and 1% did not answer.
• Continuous abstinence/recovery: The 2015 Membership Survey showed the range from less than one year up to 54 years, with a mean average of 8.32 years. The 2015 Membership Survey of 22,803 members is available on NA.org, under the "For the Public" tab.
