þéttbýlis

þéttbýlis is an Icelandic term that translates to "densely populated" or "urbanized" area. It refers to a region characterized by a high concentration of human settlements, infrastructure, and economic activity. This contrasts with dreifbýlis, which describes sparsely populated or rural areas.

In Iceland, the concept of þéttbýlis is particularly relevant due to the country's low overall population density and the concentration of its inhabitants in specific locations. The capital Reykjavík and its surrounding municipalities are the prime examples of þéttbýlis in Iceland, housing a significant majority of the nation's population. Other towns and villages that have grown to a substantial size and possess a developed infrastructure are also considered þéttbýlis.

The development of þéttbýlis areas in Iceland has been influenced by factors such as economic opportunities, access to services, and transportation networks. These areas typically feature a mix of residential buildings, commercial establishments, public facilities, and industrial zones. The distinction between þéttbýlis and dreifbýlis is important for urban planning, resource allocation, and understanding the demographic distribution within Iceland.
