The Gaza Strip is a densely populated and impoverished region inhabited primarily by Sunni Muslim Palestinian refugees; the majority live in large, overcrowded refugee camps. Arabic, Hebrew, and English are spoken. The city of Gaza is the principal city and administrative center. Other cities include Beit Lahia in the north and Khan Yunis and Rafah in the south. There were about 7,000 Israeli settlers living in 21 semimunicipal developments in the Gaza Strip until the settlements were evacuated in 2005. The number of inhabitants has fluctuated with tensions in the Middle East, increasing greatly due to the Arab-Israeli Wars.
The Gaza Strip has small construction and handicrafts industries, and some farming, including citrus fruits, olives, and livestock. However, Gaza depends on Israel for nearly 90% of its imports (largely food, consumer goods, and construction materials) and exports (mainly citrus fruit and other agricultural products), as well as employment. The economy, such as it is, has been devastated by recent fighting and, since 2007, the Israeli blockade.
