Board members rarely want every cohort table. They want to know whether the club is growing, stable, or shrinking — and whether any chapter or category is carrying unusual risk.
Prepare three answers before the meeting: the headline count versus last year, the renewal rate for the main paying category, and one sentence on the largest chapter movement.
Avoid stacking ten small charts on one slide. Dark, quiet pages with one comparison each read better in a long evening meeting than a dense dashboard printout.
If data quality is uneven, say so early. Boards tolerate imperfect rolls when they understand which figures are solid and which are estimates.
Keep the analytics section short enough that the treasurer still has time for the accounts. Membership figures support the financial story; they should not replace it.
