further housing developments took place, though on a smaller scale. in 2011 the town's population was 45,337, making it the largest in wiltshire with the exception of swindon (which is no longer within the administrative county of wiltshire), and also larger than the city of salisbury. estimates in 2018 by the office for national statistics gave a small increase to 45,620 and put trowbridge in first place at 45,822. trend-based projections for 2026 indicate a population of 49,340.
