What does a "dues base" refer to in an association's dues structure?

A "dues base" in an association's dues structure refers to the metrics used to assess dues. This concept is essential because the dues base determines how the association calculates the fees that members pay, often based on factors like membership categories, organizational size, revenue, or other specific indicators. By using metrics as the basis for dues assessment, associations can establish a fair and equitable dues structure that reflects the value of membership relative to the resources and services provided.

The other options may describe components of an association's overall financial or membership structure but do not define "dues base" as accurately. The total number of members, overall income, or a fixed rate set for dues are related concepts but do not incorporate the idea of metrics that help determine how dues are structured and assessed across different member categories.
