article: This fascinating interactive map shows where more than 231 million immigrants live around the world, and reveals that more than 7.8 million reside in the UK. The new data, released by the United Nations, shows how the number of international migrants has increased by nearly 80 million over the last 25 years. In 1995, there were more than 154 million migrants who left their home country and moved to another for various reasons. In comparison, that number had risen to 231 million globally by 2013, according to the international migrant stock trends data. The graphic, featured in The Telegraph, comes at a time when immigration is being heavily discussed by political parties, who each have varying policies on the issue in their manifestos, in the lead-up to May's election. It reveals that Great Britain and Northern Ireland are among the nations which have a high number of immigrants, with more than 7.8 million recorded. Other European countries also have similar numbers, with Germany having nine million, France recording 7.5million and Spain reporting more than six million. Meanwhile, the U.S. has more than 45 million immigrants - the most of all nations - and Russia has more than 11 million. Saudi Arabia has nine million. Countries which had the fewest number of immigrants include Morocco with 50,000, Mongolia with just 17,000 and Greenland with only 5,000. Others with low figures include Tunisia, Papua New Guinea, Cuba and Guyana. The top worldwide destinations for international migrants were the U.S., Russia, Germany, Saudi Arabia, the UAE, UK and France, according to the data. It also revealed the areas in the UK where immigrants live, with London, Leicester, the Birmingham area and Bradford among those with the highest percentage. The figures come after it emerged Prime Minister David Cameron had failed in his pledge to slash net migration to the tens of thousands before the general election. Official figures, released in February by the Office for National Statistics (ONS), show there was a net flow of 298,000 migrants to the UK in the year to September last year, equal to the population of a city roughly the size of Nottingham and up from 210,000 in the previous 12 months. The increase in net migration was driven by a 'statistically significant' rise in immigrants arriving in the UK - up to 624,000 in the year to September 2014 from 530,000 in the previous 12 months. Around 327,000 people emigrated from the UK in the same period. Mr Cameron and Home Secretary Theresa May had promised to slash net migration to below 100,000 by the end of the current parliamentary term. The figures also revealed there were significant increases in immigration of non-EU citizens - up 49,000 to 292,000 - and European Union citizens - up 43,000 to 251,000. Experts flagged another statistically significant increase in Romanian and Bulgarian citizens arriving in the UK - up to 37,000 from 24,000 in the previous 12 months. Of these, 27,000 were coming for work, a rise of 10,000 on the year ending September 2013, the ONS added. Around 271,000 people came to the UK for work, up 54,000 on a year earlier, while immigration for study rose from 175,000 to 192,000. Madeleine Sumption, director of the Migration Observatory at the University of Oxford, said at the time: 'UK job growth is likely to be a key factor behind the recent increases. 'If the UK's economic performance compared to the rest of the EU had been poor, then we might well have seen net migration fall, but that has not happened. 'Rising work-related migration from outside the EU has also contributed.' Downing Street said the rise in immigration was driven in part by Britain's economic success relative to its neighbours in the eurozone.
