The Gender Pipeline dimension of your BirdieIQ report examines the female share of your active membership and what it reveals about the club's long-term recruitment base. It is the sixth and final dimension of the BirdieIQ Full Membership Assessment.
Golf clubs have access to a significantly underrepresented pool of potential members in the female population. A club where women represent a small fraction of active members — and an even smaller fraction of the women most likely to join and stay for the long term — is drawing from a narrower pool than the market offers. The Gender Pipeline dimension measures that gap and what it means for the club's future.
The gender balance of the membership
Your report opens with the overall gender split — the proportion of active members who are male and female. For most golf clubs, this ratio leans heavily male, and the balance itself tells you something about the breadth of the membership base the club is drawing from.
Membership split by gender
An 18% female share indicates a healthy level of female representation within the membership.
The gender balance figure is a starting point, not a conclusion. An 18% female share sits at a level that indicates meaningful female participation — but the more significant question is how that female membership is distributed across age groups, and whether the club has a pipeline of younger women who are likely to become long-term members.
The pipeline age gap
The report segments the female membership by age group. Two figures sit at the centre of this analysis: the proportion of female members aged 70 and over — the group whose membership is most likely to reduce naturally over time — and the share aged 18–55, the pipeline that determines whether that reduction can be offset.
Female members aged 70+ · Share of female membership
More than three-quarters of female members are in the age group most likely to leave over time.
A 76% concentration in the 70+ category is significant on its own. But the more important question is what sits behind it — and that is where the 18–55 pipeline comes in. Women in this age range are most likely to join a club and build a decade or more of membership. A club with a meaningful pipeline here has the foundation to offset attrition from older members over time. A club where this band is thin does not.
Female members aged 18–55 · Share of total membership
Only one in twenty-five members is a woman in the prime pipeline age band.
Golf clubs generally attract relatively few younger women, so a low absolute figure is not unusual. But a 4% figure — only one in twenty-five members being a woman in the prime pipeline age band — means the club is drawing from an exceptionally narrow pool. Taken together, the two findings describe the same structural problem from opposite ends: too much of the female membership is concentrated in the age group most likely to leave, and too little is coming through to replace it.
Replacement ratio for female members
Your report also shows the female-specific replacement ratio — the number of female joiners per female leaver in the analysis period. A ratio of 1.0× indicates the club is replacing female members at exactly the rate it is losing them. A ratio below 1.0× indicates that the female membership is declining; above 1.0× indicates growth.
A replacement ratio of 1.0× for female members means the female membership is stable in absolute terms — but it is not growing, and it is not replenishing the pipeline gap. At current rates, the thin 18–55 cohort will not replace the existing older female members as they naturally leave over time. The structural position of the female membership — low share, older age profile, no pipeline growth — is one of the clearest forward risks in the report.
The risk rating
The Gender Pipeline risk rating reflects the overall female share, the pipeline age gap in the 18–55 band, and whether the female replacement ratio indicates the position is improving or holding steady.
A Strong rating indicates a healthy female share, a meaningful 18–55 pipeline, and a replacement ratio indicating growth.
A Moderate-Elevated or High rating — which applies when the female share is low, the 18–55 cohort is thin, and the replacement ratio is at or below 1.0× — indicates that the club is not tapping into a significant pool of potential long-term members. This is both a missed opportunity and a structural vulnerability: clubs with broader, more balanced memberships tend to show stronger long-term retention and stability.
The Gender Pipeline is the sixth and final dimension of the BirdieIQ Full Membership Assessment. Together, the six dimensions provide a complete picture of where your membership stands today and where it is heading.
