In the heart of the Hertfordshire commuter belt, the new town of Hemel Hempstead is affluent, but not massively so.
The town has neighbourhoods each with a small shopping centre, a pub, and a community centre. Most of these have closed circuit television, as the local council was one of the first to use this method to monitor anti-social behaviour.
The inclusion of villages, such as King’s Langley in the south, makes this constituency a pleasant mix of rural and urban Hertfordshire.
