Membership churn is the percentage of members that leave a community in a given time frame.
A high membership churn rate will slow down community growth—you’ll have to bring in more people to compensate for those who leave. It may also suggest that people don’t find value in your community. If you think this is the case, consider using some of these strategies to boost engagement.
Knowing your churn rate is essential during the growth stages of your community. It can highlight problems that you might miss if you simply look at overall growth numbers.
