How many free riders are their?

The number of free riders in a given context can vary widely depending on the situation, such as the specific public good being provided or the community involved. Free riders are individuals who benefit from resources or services without contributing to their cost, and their prevalence can be influenced by factors like social norms, enforcement mechanisms, and the perceived value of the good. To determine an exact number, one would typically need empirical data from surveys or studies related to the specific context being analyzed.
