What term refers to villages or countryside with low density and mainly agricultural employment?

The term that describes villages or countryside characterized by low population density and predominantly agricultural employment is "rural areas." Rural areas are typically distinguished from urban areas by their open spaces, natural landscapes, and the presence of farming activities. These areas often support agriculture as the primary economic activity, with smaller populations spread over greater distances compared to urban settings.

Urban areas, in contrast, are densely populated regions where the majority of the population is involved in non-agricultural jobs, and are marked by extensive infrastructure and services. Metropolitan areas encompass larger urban centers and their suburbs, generally incorporating multiple urban communities and offering a high concentration of services and employment opportunities. Urban fringes refer to transitional areas between urban and rural, where suburban development occurs but still retains some rural characteristics. Thus, "rural areas" is the most accurate term for the described characteristics in the question.
