That year "The Times" compared Welwyn Garden City with Hatfield. It described Welwyn Garden City as a world-famous modern new town developed as an experiment in community planning and Hatfield as an unplanned settlement created by sporadic building in the open country. "Welwyn, though far from perfect, made the New Towns Act possible, just as Hatfield, by its imperfection, made it necessary." In 1966, the Development Corporation was wound up and handed over to the Commission for New Towns. The housing stock, neighbourhood shopping and green spaces were passed to Welwyn Hatfield District Council between 1978 and 1983. There was a large general hospital in the town, the Queen Elizabeth II Hospital, but in 2014 emergency and inpatient services were transferred to the Lister Hospital in Stevenage. A new hospital, completed in June 2015, offers outpatient, diagnostic and ante/postnatal services. A shopping mall, the Howard Centre, was built in the 1980s, incorporating a replacement for the original "temporary" railway station. There is a resurgence of interest in the ethos of the garden city and the type of neighbourhood and community advocated by Howard, prompted by the problems of metropolitan and regional development and the importance of sustainability in government policy. On the outskirts of Old Welwyn village Roman baths are preserved in a steel vault underneath junction 6 of the A1(M) and are open to visitors. The local civic society, which aims to preserve and conserve the garden city ethos, is the Welwyn Garden City Society. The international ecumenical Focolare movement has its British headquarters at Welwyn Garden City. In 2008, during construction of a site for HSBC, 60 unsecured argonite fire suppressant cylinders discharged, killing one person, injuring six others and causing substantial damage. Three firms were later convicted of health and safety offences.  2020 saw the 100th anniversary for Welwyn Garden City with a series of celebrations planned. Welwyn Garden City had a population of 46,619 in 2011, and 51,735 (estimated) in 2016. Welwyn Garden City is part of the Welwyn Hatfield Borough and comprises seven local authority wards. It is in the county of Hertfordshire and the parliamentary constituency of Welwyn Hatfield. The MP for Welwyn Hatfield is Grant Shapps (Conservative). The nearby town of Hatfield and the village of Welwyn have parish councils with limited responsibilities, but Welwyn Garden City has none, although it had one between 1921 and 1927. Welwyn Garden City experiences a maritime or oceanic climate (Köppen climate classification "Cfb"), in common with the rest of the United Kingdom.
