Abstract: The data related to the “Ice Silk Road” region population was collected. Based on the data, the index of population density, age structure and population change were analyzed. The finding is as follows: 1) The number and density of “Ice Silk Road” region population are both extremely on low level. Population aging and loss are both serious; 2) As for Russia, the population situation is significantly different from “Ice Silk Road” regions of other countries; moreover, the natural population growth is the main influencing factor of population redistribution; 3)Among the “Ice Silk Road”, the population distribution characteristics of different regions vary considerably, which indicates “Ice Silk Road” policy should be adapted according to different regions.

Key words: “Ice Silk Road”, population, age structure, the arctic circle
