The following reasons contribute to why few people live in Siberia:
- The long distances between cities create isolation.
- The permafrost makes the construction of roads and buildings difficult.
Both of these factors significantly hinder infrastructure development and accessibility, making it challenging for populations to establish and sustain communities in the region. While there may be some concerns regarding geological activity or resource protection in specific areas, the first two reasons are more predominant in explaining the low population density in Siberia.
