Census County Business Patterns counts 3,735 manufacturing establishments with 158,521 employees in Connecticut (2023). The two federal counts differ because they define an establishment and its coverage differently.

LQ is the location quotient: the state's share of jobs in the industry divided by the U.S. share. BLS withholds some subsectors, counties and metros to protect confidentiality; those are left out of the lists above. Compare every state.
