Russian has lost more ground than any other language over the past 20 years as newly independent former Soviet states have attempted to assert their linguistic sovereignty.
The fading influence of the tongue highlights the fading influence of Moscow amid efforts by Vladimir Putin, Russia’s president, to reassert the former superpower’s importance on the world stage with its military interventions in Ukraine and Syria.
The use of Russian has retreated fastest in Kazakhstan, where in 2016 just 20.7 per cent of people said they typically spoke Russian at home, compared with 33.7 per cent in 1994, according to data from national censuses and the UN, collated by Euromonitor International, a research group.
