Russia has become more open to its' diaspora to encourage immigration into the country for the sake of labor.
With immigration also comes commerce. People have needs and they are consumers. The more immigrants into a country the more consumers can become a part of the economy provided they have an income to spend. So, Russia's immigrating diaspora are at the very least unskilled for manual labor. There is manual labor for them in Russia, so they do improve their economy.
In the graph above the ratio of men to women is mostly equal until Russians meet with the age of 65. It is at that age a severe decline in longevity occurs. The decline at 65 years old and later is disproportional with more men dying than women. But, interestingly enough those that are aged to the years of 95 and older are men.
