Kuala Lumpur
Historical demographics

Historically Kuala Lumpur was a predominantly Chinese city, although more recently the Bumiputera component of the city has grown substantially and they are now the dominant group. The Kuala Lumpur of 1872 beside the Klang River was described by Frank Swettenham as a "purely Chinese village", although a Malay stockade already existed at Bukit Nanas at that time. By 1875, after participation in the Selangor Civil War by Pahang Malays had ended, Swettenham noted Malay quarters near the Chinese area in a sketch map he had drawn. There were said to be 1,000 Chinese and 700 Malays in the town in this period. Many of the Malays may have settled in Kuala Lumpur after the war. The population of Kuala Lumpur had increased to around three thousand in 1880 when it was made the capital of Selangor. A significant component of the Malay population in Kuala Lumpur of this period consisted of Malays recruited by the British in 1880, mostly from rural Malacca, to establish a police force of 2–300, many of whom brought their families. Many of the Malays were originally from the other islands of Malay Archipelago i.e. Sumatra and Java. The Mandailings, the Minangkabaus, Javanese, and Buginese began arriving in Kuala Lumpur in the 19th century, while the Acehnese arrived in the late 20th century. In the following decades that saw the rebuilding of the town, it grew considerably with a large influx of immigrants, due in large part to the construction of a railway line in 1886 connecting Kuala Lumpur and Klang.

A census in 1891 of uncertain accuracy gave a figure of 43,796 inhabitants, 79% of whom were Chinese (71% of the Chinese were Hakka, but possibly over-counted), 14% Malay, and 6% Indian. Another perhaps more accurate survey put the population of Kuala Lumpur in 1891 at around 19,000, with 73% Chinese and 12% each for both Malays and Indians. The rubber boom in the early 20th century led to a further increase in population, from 30,000 in 1900 to 80,000 in 1920. In 1931, 61% of Kuala Lumpur's 111,418 inhabitants were Chinese, and in 1947 63.5%. The Malays however began to settle in Kuala Lumpur in significant numbers, in part due to government employment, as well as the expansion of the city that absorbed the surrounding rural areas where many Malays lived. Between 1947 and 1957 the population of Malays in Kuala Lumpur increased from 12.5 to 15%, while the proportion of Chinese dropped. The process continued after Malayan independence with the growth of a largely Malay civil service, and later the implementation of the New Economic Policy which encouraged Malay participation in urban industries and business. In 1980 the population of Kuala Lumpur had reached over a million, with 52% Chinese, 33% Malay, and 15% Indian. From 1980 to 2000 the number of Bumiputeras increased by 77%, but the Chinese still outnumbered the Bumiputeras in Kuala Lumpur in the 2000 census at 43% compared to 38%. By the 2010 census, according to the Department of Statistics and excluding non-citizens, the Malay population in Kuala Lumpur had increased to 44.7% (45.9% Bumiputera), exceeding the Chinese population of 43.2%. In the 2020 census, the percentage of the Bumiputera population in Kuala Lumpur had reached around 47.7%, with the Chinese population at 41.6% and Indians 10.0%.

A notable phenomenon in recent times has been the increased portion of foreign residents in Kuala Lumpur, which rose from 1% of the city's population in 1980 to about 8% in the 2000 census, 9.4% in 2010, and 10.5% in the 2020 census. These figures also do not include a significant number of illegal immigrants. Kuala Lumpur's rapid development has triggered a huge influx of low-skilled foreign workers from Indonesia, Nepal, Myanmar, Thailand, Bangladesh, India, Pakistan, Sri Lanka, Philippines, Vietnam, Laos and Cambodia into Malaysia, many of whom enter the country illegally or without proper permits.

Birth rates in Kuala Lumpur have declined and resulted in a lower proportion of young people – the proportion of those below 15 years old fell from 33% in 1980 to slightly less than 27% in 2000. On the other hand, the working age group of 15–59 increased from 63% in 1980 to 67% in 2000. The elderly age group, 60 years old and above has increased from 4% in 1980 and 1991 to 6% in 2000.
