Three indigenous Celtic languages are spoken in the UK: Welsh, Irish and Scottish Gaelic. Cornish, which became extinct as a first language in the late 18th century, is subject to revival efforts and has a small group of second language speakers. In the 2011 Census, approximately one-fifth (19 per cent) of the population of Wales said they could speak Welsh, an increase from the 1991 Census (18 per cent). In addition, it is estimated that about 200,000 Welsh speakers live in England. In the same census in Northern Ireland 167,487 people (10.4 per cent) stated that they had "some knowledge of Irish" (see Irish language in Northern Ireland), almost exclusively in the nationalist (mainly Catholic) population. Over 92,000 people in Scotland (just under 2 per cent of the population) had some Gaelic language ability, including 72 per cent of those living in the Outer Hebrides. The number of children being taught either Welsh or Scottish Gaelic is increasing. Among emigrant-descended populations some Scottish Gaelic is still spoken in Canada (principally Nova Scotia and Cape Breton Island), and Welsh in Patagonia, Argentina.
The UK has a partially regulated market economy. Based on market exchange rates, the UK is today the fifth-largest economy in the world and the second-largest in Europe after Germany. HM Treasury, led by the Chancellor of the Exchequer, is responsible for developing and executing the government's public finance policy and economic policy. The Bank of England is the UK's central bank and is responsible for issuing notes and coins in the nation's currency, the pound sterling. Banks in Scotland and Northern Ireland retain the right to issue their own notes, subject to retaining enough Bank of England notes in reserve to cover their issue. The pound sterling is the world's third-largest reserve currency (after the US dollar and the euro). Since 1997 the Bank of England's Monetary Policy Committee, headed by the Governor of the Bank of England, has been responsible for setting interest rates at the level necessary to achieve the overall inflation target for the economy that is set by the Chancellor each year.
More InfoThe UK service sector makes up around 79 per cent of GDP. London is one of the three "command centres" of the global economy (alongside New York City and Tokyo), it is the world's largest financial centre alongside New York, and it has the largest city GDP in Europe. Tourism is very important to the British economy; with over 27 million tourists arriving in 2004, the United Kingdom is ranked as the sixth major tourist destination in the world and London has the most international visitors of any city in the world. The creative industries accounted for 7 per cent GVA in 2005 and grew at an average of 6 per cent per annum between 1997 and 2005.
More InfoIn 2017 the average total fertility rate (TFR) across the UK was 1.74 children born per woman. While a rising birth rate is contributing to population growth, it remains considerably below the baby boom peak of 2.95 children per woman in 1964, or the high of 6.02 children born per woman in 1815, below the replacement rate of 2.1, but higher than the 2001 record low of 1.63. In 2011, 47.3 per cent of births in the UK were to unmarried women. The Office for National Statistics published a bulletin in 2015 showing that, out of the UK population aged 16 and over, 1.7 per cent identify as lesbian, gay, or bisexual (2.0 per cent of males and 1.5 per cent of females); 4.5 per cent of respondents responded with "other", "I don't know", or did not respond. In 2018 the median age of the UK population was 41.7 years.
More InfoSince 1948 substantial immigration from Africa, the Caribbean and South Asia has been a legacy of ties forged by the British Empire. Migration from new EU member states in Central and Eastern Europe since 2004 has resulted in growth in these population groups, although some of this migration has been temporary. Since the 1990s, there has been substantial diversification of the immigrant population, with migrants to the UK coming from a much wider range of countries than previous waves, which tended to involve larger numbers of migrants coming from a relatively small number of countries.
More InfoThe UK has a railway network of 10,072 miles (16,209 km) in Great Britain and 189 miles (304 km) in Northern Ireland. Railways in Northern Ireland are operated by NI Railways, a subsidiary of state-owned Translink. In Great Britain, the British Rail network was privatised between 1994 and 1997, which was followed by a rapid rise in passenger numbers following years of decline, although the factors behind this are disputed. The UK was ranked eighth among national European rail systems in the 2017 European Railway Performance Index assessing intensity of use, quality of service and safety. Network Rail owns and manages most of the fixed assets (tracks, signals etc.). Around twenty, mostly privately owned, train operating companies operate passenger trains. In 2015, 1.68 billion passengers were carried. There are about 1,000 freight trains in daily operation. HS2, a new high-speed railway line, is estimated to cost £56 billion. Crossrail, under construction in London, is Europe's largest construction project with a £15 billion projected cost.
