7.3 million from Ireland. Estimates show that by the end of the 20th century, some 300 million people of British and Irish descent were permanently settled around the globe. Today, at least 5.5 million UK-born people live abroad, mainly in Australia, Spain, the United States and Canada. Education Education in the United Kingdom is a devolved matter, with each country having a separate education system. Considering the four systems together, about 38 per cent of the United Kingdom population has a university or college degree, which is the highest percentage in Europe, and among the highest percentages in the world. The United Kingdom has some of the best universities in the world with Oxford University and Cambridge University often competing for the number 1 position on global rankings. A government commission's report in 2014 found that privately educated people comprise 7 per cent of the general population of the UK but much larger percentages of the top professions, the most extreme case quoted being 71 per cent of senior judges. England Whilst education in England is the responsibility of the Secretary of State for Education, the day-to-day administration and funding of state schools is the responsibility of local authorities. Universally free of charge state education was introduced piecemeal between 1870 and 1944. Education is now mandatory from ages 5 to 16, and in England youngsters must stay in education or training until they are 18. In 2011, the Trends in International Mathematics and Science Study (TIMSS) rated 13–14-year-old pupils in England and Wales tenth in the world for maths and ninth for science. The majority of children are educated in state-sector schools, a small proportion of which select on the grounds of academic ability. Two of the top 10 performing schools in terms of GCSE results in 2006 were state-run grammar schools. In 2010, over half of places at the University of Oxford and the University of Cambridge were taken by students from state schools, while the proportion of children in England attending private schools is around 7 per cent. Scotland Education in Scotland is the responsibility of the Cabinet Secretary for Education and Lifelong Learning, with day-to-day administration and funding of state schools the responsibility of Local Authorities. Two non-departmental public bodies have key roles in Scottish education. The Scottish Qualifications Authority is responsible for the development, accreditation, assessment and certification of qualifications other than degrees which are delivered
