Abstract

The extent to which certain subgroups of customers drive gambling revenue is a key area of interest for researchers and gambling operators alike. Interest in these areas has grown substantially in recent years, perhaps in part due to the expansion of online and land-based gambling in the United States (e.g., sports betting) and worldwide. However, we know little about the stability of customer revenue distributions. Understanding the stability of revenue distributions is an important step to more fully understanding the scope of risk for gambling harm to individuals over time. Research about the distribution of gambling activity and what percentage certain subgroups of gamblers are responsible for is mixed, with some studies showing a “Pareto” distribution (i.e., a small or “vital few”, or about 20% responsible for about 80% of activity, and a larger or “trivial many”, or about 80% responsible for the remaining 20% of activity), and others identifying different distributional forms. This lightning talk will explore how members of the “vital few” and “trivial many” groups might change or remain stable over time, and how both group membership and changes (or stability) in group membership might predict the risk of gambling-related problems.

A better understanding of the percentage of customers who contribute to the majority of gambling revenue is important for researchers so they can learn more about the characteristics of this group. Gambling operators can use this knowledge to enhance player safety and responsible gambling programs.
