In 1998, the Haredi population in the Jewish community of the United Kingdom was estimated at 27,000 (13% of affiliated Jews). The largest communities are located in London, particularly Stamford Hill, in Salford and Prestwich in Greater Manchester, and in Gateshead. A 2007 study asserted that three out of four British Jewish births were Haredi, who then accounted for 17% of British Jews, (45,500 out of around 275,000). Another study in 2010 established that there were 9,049 Haredi households in the UK, which would account for a population of nearly 53,400, or 20% of the community. The Board of Deputies of British Jews has predicted that the Haredi community will become the largest group in Anglo-Jewry within the next three decades: In comparison with the national average of 2.4 children per family, Haredi families have an average of 5.9 children, and consequently, the population distribution is heavily biased to the under-20-year-olds. By 2006, membership of Haredi synagogues had doubled since 1990.
