Roughly 1.25 million Russians have left the country in the last 10 years, Sergei Stepashin, head of the national Audit Chamber, told the radio station Echo of Moscow. The chamber tracks migration through tax revenues.
He said the exodus is so large, it's comparable in numbers to the outrush in the wake of the Bolshevik Revolution.
"About as many left the country after 1917," he said.
About 20% of Russians are thinking about leaving the country and trying their luck abroad, according to various Russian polling agencies, from the independent Levada Center to the Kremlin-friendly VTsIOM. Among 18- to 35-year-olds, close to 40% of respondents say they'd like to leave.
The wave of emigration, which has included large numbers of educated Russians, has grave implications for a country of 142 million with a death rate significantly higher than its birthrate. A study published this year by the Berlin Institute for Population and Development called Russia a waning power and predicted its population would shrink by 15 million by 2030.
Experts believe that 100,000 to 150,000 people now leave the country annually and warn that the exodus reached dangerous dimensions in the last three years.
