Rank is among the 64 Louisiana parishes (only those with published figures are ranked). Percentile is the share of the other ranked parishes with lower density. A change shown as a range (for example "+6 to +8") means the 2018 figure was withheld for having fewer than 3 establishments, so only the range is known.

Counts are business establishments (locations) from the Census Bureau's 2023 County Business Patterns; density uses 2023 population estimates. The index measures supply, how many establishments exist per resident, and says nothing about demand, revenue, or profitability. See the methodology.
