This is necessary to preserve sovereignty. So explained his initiative in a letter to Russian President Vladimir Putin chairman of the supervisory board of the Institute of Demography, Migration and Regional Development Yuri Krupnov. In this and the following centuries the world will be divided. There will be 7 civilizations: the European (including the USA and Canada) with 900 million people, the Islamic with 1.1 billion, the African with 800 million, Latin American (600 million), Chinese (1.4 billion), Indian (1.3 billion) and Russian (about 160 million people), writes RT. And since our country will be surrounded by "billion" civilizations, it may lose its independence. And exclusively on the demographic grounds of its geographical boundaries will change, warned the expert. To prevent this, over the next 100 years, we need to launch a strategy to multiply the population of Russia, suggested to Putin Krupnov. To work this program, according to the demographer, the first priority is to support large families. For them, "with the birth of every fourth child, there must be a kind of communism," said the expert.. This should be expressed in the provision of each such family with a state of a spacious house with all the necessary infrastructure, as well as a kind of "family salary" in the amount of 100 thousand. rubles. "This will translate the family by status and opportunities into a privileged position," explained Krupnov. Last year, according to the Federal Statistics Service, the birth rate in Russia fell by 10.7%. After 18 years, the population of our country at the best will be 156.2 million people, and at worst - 137.4 million people, according to Rosstat.
