The distribution of contributors will likely be found to be a Pareto distribution, which is the basis of the familiar 80-20 rule: 80 percent of anything is attributable to 20 percent of the possible sources  (more or less).  The distribution parameters
vary, but the shape is relatively constant.  Given an accurate analysis of the count of contributions from the actual contributors, one could theoretically make a very good guess at the total size of the potential contributors; or, given the count of
contributors and the number of contributions from the most active, one could predict the number of contributions from the nth ranked contributor to some relatively high degree of accuracy.  Chalk it up to human nature.
