Where Connecticut is over and under the national average

Per resident, Connecticut runs heaviest in septic and drainage services (70 establishments, index 2.37, 11th nationally by count); landscaping and tree services (2,258 establishments, index 1.78, 19th nationally by count); machine shops (309 establishments, index 1.75, 15th nationally by count). That top index of 2.37 means 137% more septic and drainage services per Connecticut resident than the U.S. average. A buyer pricing a Connecticut deal in that category has real comparables to work from.

At the other end, Connecticut is thinnest in local general freight trucking (index 0.46) and pest control companies (index 0.64). A low index can mean an underserved market for a buyer building a platform, or simply that demand in Connecticut is met from neighboring states.
