The article examines the criteria for classifying regions in the Far North as part of the Arctic Zone within the Russian Federation. It evaluates a range of factors, including natural and climatic conditions, socio-economic aspects, and the medical and biological characteristics of the territories. Additionally, the article presents the outcomes of zoning the northern territories of the Russian Federation based on the natural and climatic conditions that impact human life. This analysis resulted in the identification of three criteria for determining the inclusion of territories in the Arctic Zone of the Russian Federation: the vegetation component of landscapes in its zonal distribution; the CAFF boundary, which proposed by the Arctic Council’s Arctic Flora and Fauna Conservation Working Group; and the level of ultraviolet deficiency, which reflects the direct impact of latitude on the natural environment and human health. These criteria are characterized by their clarity and ease of interpretation, and do not require the development or endorsement of supplementary methodological guidelines. They are easily grasped by both regional leaders and residents regarding the inclusion or exclusion of areas from the Arctic Zone of the Russian Federation. Consequently, these criteria can be effectively integrated into federal legislation as directly applicable norms.
