Most of it is concentrated in the southern parts. Given the vast territory of the Russian Far East, 6.3 million people translates to slightly less than one person per square kilometer, making the Russian Far East one of the most sparsely populated areas in the world. The population of the Russian Far East has been rapidly declining since the dissolution of the Soviet Union (even more so than for Russia in general), dropping by 14% in the last fifteen years. The Russian government had been discussing a range of re-population programs to avoid the forecast drop to 4.5 million people by 2015, hoping to attract in particular the remaining Russian population of the near abroad but eventually agreeing on a program to resettle Ukrainian Illegal immigrants.
