Nearly a half of Georgia's population lives in rural areas, where low-intensity self-sufficient farming provides the principal source of livelihood. Georgian statistics service puts individual persons into the category of self-employed workers. As of 2007 416,900 persons were listed as self-employed in agriculture. For large families, heads of households are typically described as "individual entrepreneurs", members of the family that help to cultivate land are classified as "unpaid family business workers". The use of this methodology produces relatively low unemployment rates for rural areas rather in urban areas and in Tbilisi.
