Which parts of Europe are least densely populated in Europe?

* Scandinavia: The Nordic countries of Sweden, Norway, and Finland are among the least densely populated countries in Europe, with an average population density of less than 25 people per square kilometre. This is due to a combination of factors, including the harsh climate, the rugged terrain, and the economic reliance on natural resources such as forestry and fishing.

* Eastern Europe: Several countries in Eastern Europe, including Romania, Bulgaria, and Moldova, have relatively low population densities, ranging from 60 to 80 people per square kilometre. This is partly due to the legacy of communism, which resulted in a decline in population growth rates and an increase in emigration.

* The Alps: The mountainous regions of the Alps, which span several countries in Central and Southern Europe, are also relatively sparsely populated. This is due to the difficult terrain and the limited opportunities for agriculture and industry.

* Rural areas: In general, rural areas throughout Europe are less densely populated than urban areas. This is due to the fact that most economic activity and population growth is concentrated in cities and towns.
