Methodology

Counts are businesses registered with the state of Connecticut whose formation (registration) date falls in the period shown and that appear on the state register in ListRiver's data. City is the business address on file, with spellings as the state records them. Businesses already dissolved are not counted, so the earlier 12 months are slightly understated and increases slightly overstated; the effect is similar across a state's cities, so the order is a fair comparison.
