The size of a chapter plays a significant role in the quantity and quality of referrals generated. As a chapter grows, members gain access to a broader network of professionals, increasing opportunities for collaboration and referrals. This relationship between chapter size and referral activity highlights the importance of building and maintaining an optimal chapter size.

Chapter Size and Monthly Referral Activity
The table below outlines how chapter size directly correlates with the average number of monthly referrals:
Members | Monthly Referrals |
10-12 | 10-20 |
13-15 | 21-35 |
15-19 | 36-48 |
20 (The Tipping Point) | 49-124 |
21-25 | 88-144 |
26-34 | 145-234 |
35+ | 235+ |
The Tipping Point
A key milestone is when a chapter reaches 20 members — the tipping point. At this size, referral activity can significantly increase, as members have more diverse networks to leverage. This growth drives momentum, boosting the overall effectiveness of the chapter and benefiting all members involved.
Optimizing Your Chapter Size
Recruitment Matters
Actively invite quality members to your chapter to reach and exceed the 20-member tipping point.
Engage Members
Foster engagement and collaboration to maximize referral opportunities.
Monitor Growth
Chapter leaders should regularly assess the chapter's size and referral activity. For chapters with fewer than 20 members, review this data quarterly; for larger chapters, assess semi-annually.
By understanding the link between chapter size and referral activity, chapters can focus on strategic growth to ensure members achieve their business goals.
