The Most Oversaturated Business Markets in America

Some industries have so many businesses per capita that competition is fierce. Here are the most crowded markets based on firms per 100K people.

Market saturation matters when deciding what business to start. An industry with 60+ firms per 100,000 people means fierce local competition. We calculated saturation for every industry using Census business counts and population data.
