These are lists of the most common Chinese surnames in China (People's Republic of China), Taiwan (Republic of China), and the Chinese diaspora overseas as provided by authoritative government or academic sources. Chinese names also form the basis for many common Cambodian, Vietnamese, Korean, and Japanese surnames and to an extent, Filipino surnames in both translation and transliteration into those languages. The conception of China as consisting of the "old 100 families" () is an ancient and traditional one, the most notable tally being the Song-era Hundred Family Surnames (). Even today, the number of surnames in China is a little over 4,000, while the year 2000 US census found there are more than 6.2 million surnames altogether and that the number of surnames held by 100 or more Americans (per name) was just over 150,000. The Chinese expression "Three Zhang Four Li" () is used to mean "anyone" or "everyone", but the most common surnames are currently Wang in mainland China and Chen in Taiwan. A commonly cited factoid from the 1990 edition of the Guinness Book of World Records estimated that Zhang was the most common surname in the world, but no comprehensive information from China was available at the time and more recent editions have not repeated the claim. However, Zhang Wei (张伟) is the most common full name in mainland China. The top five surnames in China – Wang, Li, Zhang, Liu, Chen – are also the top five surnames in the world, each with over 70-100 million worldwide. Greater China China This list of the 100 most common Chinese surnames derives from China's Ministry of Public Security's annual report on the top 100 surnames in China, with the latest report release in January 2020 for the year 2019. When the 1982 Chinese census was first published, it did not include a list of top surnames. However, in 2004, the State Post Bureau subsequently used the census data to release a series of commemorative stamps in honor of the then-most-common surnames in 2004. The summary of the 2007 survey revealed China had approximately 92,881,000 Wangs (7.25% of the population), 92,074,000 Lis (7.19%), and 87,502,000 Zhangs (6.83%). A 2018 survey showed that Liu and Chen were the next most common China with more than 70 million each. These top five surnames— Wang, Li, Zhang, Liu, Chen—alone accounted for more people than Indonesia, the fourth most populous country
