Beijing is located in Northern China and is the country's second largest city, after Shanghai. The population of Beijing's urban core (city proper) is around 7.5 million. The population of Beijing Municipality, defined as the total number of people who reside in Beijing for 6 months or more per year, was 17.43 million in 2007.

A sizable international community exists in Beijing, mostly attracted by the highly growing foreign business and trade sector, and many live in the Beijing urban area's densely populated northern, northeastern and eastern sections.

The urban area of Beijing is situated in the south-central part of the municipality and occupies a small but expanding part of the municipality's area. It spreads out in bands of concentric ring roads, of which the fifth and outermost (the Sixth Ring Road - the numbering starts at 2) passes through several satellite towns. Tian'anmen (Gate of Heavenly Peace) and Tian'anmen Square are at the centre of Beijing, and are directly to the south of the Forbidden City, former residence of the emperors of China. To the west of Tian'anmen is Zhongnanhai, residence of the paramount leaders of the People's Republic of China. Running through central Beijing from east to west is Chang'an Avenue, one of Beijing's main thoroughfares.

In 2006, Beijing's nominal GDP was 772.03 billion RMB (about 97 billion USD), a year-on-year growth of 12% from the previous year. Its GDP per capita was 49,505 RMB, an increase of 8.8% from the previous year and more than twice as much as in 2000. In 2005, Beijing's primary, secondary, and tertiary industries were worth 9.77 billion RMB, 210.05 billion RMB, and 461.63 billion RMB. In 2006, Urban disposable income per capita was 19,978 yuan, a real increase of 12.9% from the previous year. Per capita pure income of rural residents was 8,620 RMB, a real increase of 9.6%. Per capita disposable income of the 20% low-income residents increased 16.7%, 11.4 percentage points higher than the growth rate of the 20% high-income residents. The Engel's coefficient of Beijing's urban residents reached 31.8% in 2005 and that of the rural residents was 32.8%, declining 4.5 percentage points and 3.9 percentage points, respectively, compared with 2000.

Beijing's real estate and automobile sectors have continued to bloom in recent years. In 2005, a total of 28.032 million square metres of housing real estate was sold, for a total of 175.88 billion RMB. The total number of cars registered in Beijing in 2004 was 2,146,000, of which 1,540,000 were privately-owned (a year-on-year increase of 18.7%).

The Beijing CBD, centred at the Guomao area, has been identified as the city's new central business district, and is home to a variety of corporate regional headquarters, shopping precincts, and high-end housing. The Beijing Financial Street, in the Fuxingmen and Fuchengmen area, is a traditional financial centre. The Wangfujing and Xidan areas are major shopping districts. Zhongguancun, dubbed "China's Silicon Valley", continues to be a major centre in electronics - and computer-related industries, as well as pharmaceuticals-related research. Meanwhile, Yizhuang, located to the southeast of the urban area, is becoming a new centre in pharmaceuticals, IT, and materials engineering.

Major industrial areas include Shijingshan, located on the western outskirts of the city. Agriculture is carried out outside the urban area of Beijing, with wheat and maize (corn) being the main crops. Vegetables are also grown in the regions closer to the urban area in order to supply the city.

Beijing is increasingly becoming known for its innovative entrepreneurs and high-growth start-ups. This culture is backed by a large community of both Chinese and foreign venture capital firms, such as Sequoia Capital, whose head office in China resides in Chaoyang, Beijing. Though Shanghai is seen as the economic centre of China, this is typically based on the numerous large corporations based there, rather than as a centre for Chinese entrepreneurship.

The development of Beijing continues to proceed at a rapid pace, and the vast expansion of Beijing has created a multitude of problems for the city. Beijing is known for its smog as well as the frequent "power-saving" programmes instituted by the government. Citizens of Beijing as well as tourists frequently complain about the quality of the water supply and the cost of the basic services such as electricity and natural gas. The major industrial areas outside of Beijing were ordered to clean their operations or leave the Beijing area in an effort to alleviate the smog that covers the city. Most factories, unable to update, have moved and relocated to other cities such as Xi'an, China.

Beijing also holds the record for the largest settlement based in the eastern and northern hemispere reaching over 3 million people.
