Actually, it is a pretty normal Pareto distribution applicable to many fields. Here are just two examples.

Sales: 80% of your sales come from 5% of your customers; 15% of your sales come from 15% of your customers; 5% of your sales come from 80% of your customers.

Purchasing: 80% of your purchases come from 5% of your vendors; 15% of your purchases come from 15% of your vendors; 5% of your purchases come from 80% of your vendors.

In either case, we are talking dollar volume, not number of incidents. We are also talking at a manufacturing/marco level; not an individual retail/micro level.

That’s really cool, thanks for the post. I was familiar with gaussian distributions (from physics - lasers have gaussian distributions for example) but not Pareto distributions.
