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'.

Membership activity
For 2023, approximately hours of preaching were reported and around  new members were baptized. The Watch Tower Society reported that Jehovah's Witnesses conducted about home Bible studies with non-members, including Bible studies conducted by Witness parents with their children.

Jehovah's Witnesses' official statistics only count as members those who submit reports for preaching activity, usually resulting in lower membership numbers than those found by external surveys. For example, in 2014 Jehovah's Witnesses reported approximately 1.2 million active publishers in the United States, whereas the Pew Research Center reported that Jehovah's Witnesses make up 0.8% of the US population (approximately 2.5 million) in that year. Their official statistics indicate membership according to various territories&mdash;which they refer to as "lands"&mdash;many of which are not independent countries.

According to official statistics, about people worldwide attended Jehovah's Witnesses' 2023 observance of the Memorial of Christ's death (also termed the Lord's Evening Meal). Of those, around people partook of the memorial emblems of unleavened bread and wine. Those who partake profess to be of the 144,000 "anointed" and hope to go to heaven, based on their interpretation of Revelation 14:1.

Congregations are generally organized geographically, and members are directed to attend the Kingdom Hall to which their neighborhood has been assigned, resulting in an ethnic mix generally representative of local population, though congregations based on language and ethnicity have also been formed.
