Access to improved water supply and sanitation in the UK is universal. It is estimated that 96.7 per cent of households are connected to the sewer network. According to the Environment Agency, total water abstraction for public water supply in the UK was 16,406 megalitres per day in 2007. Drinking water standards and wastewater discharge standards in the UK, as in other countries of the European Union, were formerly determined by the EU when the UK was a member state (see Water supply and sanitation in the European Union).
The 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.
More InfoSince the 1980s, UK economic inequality, like Canada, Australia and the United States, has grown faster than in other developed countries. The poverty line in the UK is commonly defined as being 60 per cent of the median household income. The Office for National Statistics has estimated that in 2011, 14 million people were at risk of poverty or social exclusion, and that one person in 20 (5.1 per cent) was experiencing "severe material depression", up from 3 million people in 1977. Although the UK does not have an official poverty measure, the Joseph Rowntree Foundation and the Social Metrics Commission estimate, based on government data, that there are 14 million people in poverty in the UK. 1.5 million people experienced destitution in 2017. In 2018, the UN Special Rapporteur on Extreme Poverty and Human Rights visited the UK and found that government policies and cuts to social support are "entrenching high levels of poverty and inflicting unnecessary misery in one of the richest countries in the world." His final 2019 report found that the UK government was doubling down on policies that have "led to the systematic immiseration of millions across Great Britain" and that sustained and widespread cuts to social support "amount to retrogressive measures in clear violation of the United Kingdom’s human rights obligations."
More InfoIn the decades-long process of European integration, the UK was a founding member of the alliance called the Western European Union, established with the London and Paris Conferences in 1954. In 1960 the UK was one of the seven founding members of the European Free Trade Association (EFTA), but in 1973 it left to join the European Communities (EC). When the EC became the European Union (EU) in 1992, the UK was one of the 12 founding members. The Treaty of Lisbon, signed in 2007, forms the constitutional basis of the European Union since then.
More InfoIn the final quarter of 2008, the UK economy officially entered recession for the first time since 1991. Following the likes of the United States, France and many major economies, in 2013, the UK lost its top AAA credit rating for the first time since 1978 with Moodys and Fitch credit agency, but, unlike the other major economies, retained its triple A rating with Standard & Poor's. By the end of 2014, UK growth was the fastest in both the G7 and in Europe, and by September 2015, the unemployment rate was down to a seven-year low of 5.3 per cent.
