Egypt occupies about one millions km2 of land in the north–east corner of Africa. The Nile River traverses the country from south to north dividing it into the western and the eastern desert. Throughout its long history, population and economic activities concentrated in the narrow and limited area in the Nile Valley and Delta. According to the 2006 census, Egypt’s population is estimated at 73 million living on 5.5% of the total area of the country. Population is projected to reach 94 million by 2020 and101 million by 2025, an addition of almost 1.35 million annually. Cairo, the capital of Egypt, is located in a strategic location, with a total population of about 14 million in 2006, and a density of about 40,000 p/km2 (estimated 2000). It is the tenth largest mega-city in the world and expected to grow over 20 million by the year 2017. Greater Cairo is comprised of 3 Governorates – Cairo (8 million), Giza (3.5 million), and Shubra El-Kheima and other areas from Qualiobya (2.5 million), with an area of about, 524,4 km2 in 2000, and a total urban population of about 43% of Egypt. Within the last three decades, its total built-up area increased more than 270%. Cairo, has suffered from serious urban problems, both physical and social, as other large cities in developing countries, problems of transportation, lack of adequate drainage and sewerage, and lack of usable spaces and green areas, beside the squatters within the city map. In 1974, a master plan for the greater Cairo was approved to face current and future urban problems and to control the growth on agricultural land, since most of the outer growth of the city has taken place on agricultural land, indicating the urgency of providing desert land for urban expansion. In the late seventies, the government started establishing new cities and communities away from the Nile delta and valley, to redistribute population and economic activities. Furthermore, the governments target was to upgrade the quality of the living environment, and to protect agricultural land. Now new urban settlements are bounding Cairo on its outer ring road. Due to the global change and privatization concept, the private sector participated in the development process and infrastructure of these urban settlements. Recently Egyptian companies, investors and businessmen are investing in the development of high-quality housing for the rich in the new communities around Cairo. In the nineties, several compounds were being constructed in 6th of October City, El-Sheikh Zayed, New Cairo, Badr and El-Shrouk. Such compounds consist of distinguished large-areas with villas and mansions, huge green open spaces, and exclusive recreational and social amenities, including all types of luxuries. The trend towards gated communities is accelerating in Egypt, in response to global change. Private investment in the housing and real estate sectors has increased continuously during the past two decades. Most families from the upper class who were living at the best residential areas in the city, moved to the new communities, escaping from the polluted environment, crowdedness, lake of facilities and other existing problems in their neighborhoods. Although there are many housing projects in the new cities and communities, the majority of the families (middle and lower classes) who are in need to shelter cannot afforded the supply which remains unoccupied. The objective of this paper is to present the demographic growth of Cairo city and its urban problems, , It focuses on the new settlements around Cairo, The paper evaluates the socio-economic concept of gated communities in the suburbs around the city, as an impact of the global change. It exposes to the identity of gated communities as a global culture, and its advantages and disadvantages.
