Society and new and tighter licensing controls by the City of Westminster led to a crackdown on illegal premises. The number of sex industry premises dropped from 185 in 1982 to around 30 in 1991. By 2000, substantial relaxation of general censorship, the ready availability of non-commercial sex, and the licensing or closing of unlicensed sex shops had reduced the red-light area to just a small area around Berwick Street. Much of the business has been reported to have been run by Albanian gangs. By the end of 2014, gentrification and competition from the internet had reduced the number of flats in Soho used for prostitution, but the area remains a red-light district and a centre of the sex industry in London. Health and welfare The National Hospital for Diseases of the Heart and Paralysis was established at No. 32 Soho Square in 1874. The property had previously been owned by the naturalist and botanist Sir Joseph Banks. It moved to Westmoreland Street in 1914, and then to Fulham Road in 1991. In July 2019, Soho was reported to be the unhealthiest place to live in Britain. Researchers from the University of Liverpool found that the area had the greatest access to takeaways, pubs and off-licences and these were combined with high levels of air pollution and low levels of parks and green spaces. Streets Berwick Street was built between 1687 and 1703, and is probably named after James FitzJames, 1st Duke of Berwick, the illegitimate son of James II of England. It has held a street market since the early 18th century, which has been formally organised since 1892. Carnaby Street was laid out in the late 17th century. It was named after Karnaby House, built on the street's eastern side in 1683. It was a popular residence for Huguenots at first, before becoming populated by shops in the 19th century. In 1957, a fashion boutique was opened, and Carnaby Street became the fashion centre of 1960s Swinging London, although it quickly became known for poor quality "kitsch" products. D'Arblay Street was laid out between 1735 and 1744. It was originally known as Portland Street after William Bentinck, 2nd Duke of Portland and given its current named in 1909 in commemoration of Frances Burney, Madame D'Arblay, who had lived in Poland Street nearby, when she was young. The George public house at No. 1 was opened in 1889, but
