"the baby boom" doesn't help: working hands is getting smaller demographic statistics in russia resembles the statistics of the war period: the population is shrinking every year 700 thousand people. mortality is twice that in developed countries, and life expectancy among men is the lowest in the world, 60 years. now if in the country of 142 million people, by 2050 there may remain only 100 million vladimir putin in 2000 indicated that the population decline threatens the very existence of russia. six years later he increased support for mothers and offered a premium for the birth of her second child. the birth rate began to rise, but the mortality rate has not declined, as did not increase lifespan. putin cheered and said that in the next three to four years the country will be able to stabilize the demographic situation. in fact, reasons for optimism are few, and to achieve this goal, increasing the population of the russian federation up to 145 million people, it is impossible, experts say. the head of the center for demography and human ecology anatoly vishnevsky says that one of the "baby boom" does not mean anything: it's possible that people decide to have children now, while this form of the prize, but in the long term the total number of children in families will not increase. the middle class will not tempt the cash payments. scientists attribute the current surge in the birth rate that matured and began to start families, many children of the 1980-ies. but the next generation of parents will be much fewer in number.
