This is is a graphic that ranks states by their percentage of micro-sized establishments. Note that establishments are defined by the Department of Labor as physical business locations. Based on this definition, a large business could have multiple micro or small establishments in the same region (e.g., a Wells Fargo branch with 20 employees is a small establishment, but those workers are part of a very large bank). Also self-proprietors — those who own unincorporated businesses — are not included in County Business Patterns data.
