Macao, also called Macau, is on the western side of the Pearl River entrance, at the head of which is the Chinese port of Guangdong and it stands opposite Hong Kong which is on the eastern side of the entrance. It is made of a small narrow peninsula(半岛) sticking out from Guangdong province. The total area of Macao is about 21.45 square kilometers, and it is made up of three parts: Macao Peninsula, Dingbat Isle and Lehman Isle.
Between Macao Peninsula and Dingbat Isle there are two bridges which join the two parts together, and there is also a highway between the Dingbat and Lehman Isles. Therefore, two bridges and one highway make the three parts of Macao into an integrated region(一个整体).
Macao faces to the vast sea and its back is the Pearl River Delta. The two big cities, Hong Kong and Guangzhou, and the two special economic zones Hula and Shenzhen are its neighbors. All of this offers much advantage for its economic development.
Macao has a population of about 450, 000. This is very large against the size of the area. The average population density(密度) reaches 20, 000 per square kilometer. It is one of the densest population regions in the world. The majority of its people are Chinese, who make up 96% of the whole population.
