Family life is important for Libyan families. Most Libyans live in apartment blocks and various kinds of independent housing units depending on their income status. Most of the Arabs who have lived a nomadic lifestyle, traditionally in tents, have been settled into various towns and cities in Libya, their old way of life fading out. It is believed that there are still some who do live as they have for centuries in the desert, though no one knows their exact numbers. Most of the population are engaged in occupations in industry and services and a small percentage in agriculture.
