The NY families are smaller than they were at their peak in the 1950's and 1960's but that's due as much to them closing the books for years at a time as anything else, including general attrition. Unlike pretty much every other family, the NY families have been able to keep their total memberships stable for the last 20 years or so. Of course, as mentioned before, there is also attrition in terms of quality, not just quantity.
