The survey found that membership organizations reported improved membership growth in 2011 compared to 2010. Specifically, 49% reported an overall increase in total membership in 2011 compared to 36% in 2010. New member acquisition and membership renewals also improved. However, challenges to membership growth remain. The survey identified which challenges were most likely to inhibit growth, such as weak offerings or insufficient budget, and which were less detrimental, such as inadequate staffing. The survey also found that higher member participation in activities like conventions correlated with increased renewal rates.
