Migration may be the only way to stop the decline of the Moscow population, says a document created by the city committee on interregional relations and national policies. RIA Novosti obtained a copy of the document, which states that by 2025, the working population of the city will decrease, significantly changing the dynamics of the labour market in the capital, and that a growing percentage of the working population will not be ethnically Russian. At the moment, 84.5 per cent of the city`s citizens are ethnic Russians, but this figure is liable to change. Moscow currently houses more than 10 million people of more than 160 nationalities. In the last decade, neighborhoods with concentrations of ethnic minorities began appearing, according to the report. Recent migrants, particularly the Chinese, Vietnamese and those from the Caucasus, tend to form a closed, isolated subculture, which in turn leads many Muscovites to feel that the culture of their city is being threatened by these newcomers. The report says that eradicating extremism, xenophobia and domestic nationalism is a priority for the city authorities, and that improving migration legislation is essential. The city aims to crack down on the low-wage paying black market of labour, reduce illegal migration and work out an "effective use of the foreign and regional workforce."
