Demographics of Jehovah's Witnesses

As of 2023, Jehovah's Witnesses reported a monthly average membership of approximately 8.6 million actively involved in preaching, with a peak of around 8.8 million. Jehovah's Witnesses have an active presence in most countries, though they do not form a large part of the population of any country.

To be counted as an active member, an individual must be a publisher, and report some amount of time preaching to non-members. Jehovah's Witnesses' preaching activity is self-reported, and members are directed to submit a 'Field Service Report' each month. Baptized members who fail to submit a report every month are termed 'irregular'. Those who do not submit a report for six continuous months are termed 'inactive'.
