Ethnic groups
→ Main article: Demography of Malaysia
The population of Malaysia is composed as follows: 50.4% are Malays, 23.7% Chinese, 11% indigenous peoples (Orang Asli and Dayak), 7.1% Indians and 7.8% others.
The population is not evenly distributed throughout Malaysia, as only about 5 million people (about 20% of Malaysia's population) live in the eastern part of Malaysia, i.e. the two states of Sarawak and Sabah on the island of Borneo, although the two states together account for about 60% of Malaysia's land area, while the remaining 80% of the population (about 22 million people) live in the smaller western part of the country.
The Malays, who largely belong to Sunni Islam, have claimed political leadership since Malaysia's independence; they are systematically promoted by the government and given preferential treatment in the civil service, which has been ensured by the so-called Bumiputra status since the introduction of the Malaysian new economic policy in the 1960s. Furthermore, overseas Chinese make up about a quarter of the population. They currently still dominate in the cities. The Chinese play a significant role in trade and commerce. Another seven percent of the population is of Indian origin. These are Hindus, Muslims, Sikhs, Christians or Buddhists. About 85% of Malaysia's Indian-origin population are Tamils, with minority groups being the Malayalis, Punjabis and Telugus.
In the sparsely populated East Malaysian states of Sarawak and Sabah, indigenous ethnic groups who are not ethnic Malays make up half and two-thirds of the population respectively. Like the Malays, they are counted as part of Malaysia's original population and are thus also considered Bumiputras. These indigenous ethnic groups are collectively referred to as Dayak in Sarawak and include the Iban and the Bidayuh, among others. In Sabah live indigenous ethnic groups such as the Murut or the Kadazan.
On the Malay Peninsula, indigenous people also exist, but in smaller numbers, they are referred to by the collective term Orang Asli. These belong to a large number of ethnic groups, but have cultural commonalities. They were followers of animist local religions until the 20th century. Since then, many have converted to Christianity or Islam. Although the Orang Asli differ from the Malays in terms of culture, many have assimilated Malay culture, such as by moving to the cities or by marriage. Some groups of Temiar Senoi have retreated to the inaccessible mountain rainforests of north-central Malaysia, where they live as isolated peoples.
Notable minorities are the Europeans, people from the Middle East, Cambodia and Vietnam. The Europeans are mostly British and some Portuguese whose ancestors have lived there since colonial times. Most Cambodians and Vietnamese came to Malaysia as Vietnam War refugees.
In total (as of 2021), about four to six million immigrants live in Malaysia. Most of the labour migrants come from Nepal, Bangladesh, Indonesia or Myanmar.
Population growth is relatively high at about 1.6% per year, and about one-third of the population is under 15 years old. The urbanization rate is about 75 %. The average life expectancy from 2010 to 2015 was 74.7 years (men: 72.6 years, women: 77.1 years) the infant mortality rate was about 13 per thousand. The average age in 2016 was 28.2 years. A woman had an average of 1.9 children, which is why the population will age significantly in the future.
Languages
The official language of Malaysia is Bahasa Malaysia (Malay). The English language enjoys a special role due to the long British colonial period in Malaysia and is a second language for many Malaysians. Due to a large Chinese minority, Chinese also plays an important role (especially Cantonese, High Chinese, Hokkien, Hakka, Chaozhou (Teochew), Hainan, the Fuzhou dialect). Due to the Indian minority also living in Malaysia, numerous Indian languages, especially Tamil, Telugu and Malayalam are widely spoken. A large number of indigenous languages are also spoken in East Malaysia, the most important of which are Iban and Kadazan. A total of 140 different languages and idioms are spoken in Malaysia.
British English is used in official documents. However, American English has already made some inroads through television. The English used in the colloquial language in Malaysia is very different from British English and is therefore also called Manglish. It is very similar to the Singlish spoken in Singapore except for some slang expressions.
Religions
Overview
All world religions are represented in Malaysia in significant numbers.
Censuses show roughly the following population proportions by religion:
| Year | Islam | Buddhism | Christianity | Hinduism | Chinese folk religions such as Daoism, Confucianism | Non-Denominational | Other confessions or no information |
| 2000 | 60,4 % | 19,2 % | 9,1 % | 6,3 % | 2,6 % | | 2,4 % |
| 2010 | 61,5 % | 19,6 % | 9,2 % | 6,3 % | 1,3 % | 0,7 % | 0,5 % |
The Chinese are mostly Buddhists (20%) or belong to other Chinese religions such as Daoism or Confucianism (2.6%). Christians (9 %) are found in all ethnic groups. Indians consist of Hindus and Sikhs (6.5 %).
Islam
Islam, which 60% of the population professes, is the state religion. The Shāfiʿite school of Sunni Islam
is practiced in theology and jurisprudence. Other Islamic schools, especially Shiite schools, are prohibited.
Malaysia first came into contact with Islam through Arab traders and merchants as early as the end of the 7th century. However, at that time various Buddhist and Indian-Hindu kingdoms prevailed in Malaysia, so that Muslims never made up more than 10% of the population until the 14th century. From the 13th century onwards, more Arabs settled in Malaysia, eventually mixing with the indigenous population and thus furthering the Islamization of the Malays. Like Indonesia, Malaysia was Islamized in the 14th and 15th centuries.
Until well into the 1970s, many Muslim Malays were considered liberal (similar to the Abangan in present-day Indonesia). However, with the Dakwah, an Islamic revivalist movement, a wave of Islamization began (triggered by various ethnic and social conflicts, see among others Parti Islam Se-Malaysia and Al-Arqam), so that Malaysia today is orthodox Islamic. Malays, who make up 50.4% of the total population, are virtually all Muslims. About 70% of Malaysian women of Malay origin wear headscarves. Traditional Malay clothing of Islamic origin is also worn by many Malays.
According to the country's constitution, all ethnic Malays are automatically Muslims by birth. They cannot marry people of other faiths. Apostasy from Islam is highly disliked and in practice is difficult. To do so, a "Borang Keluar Islam" (form for leaving Islam) must first be filled out. Afterwards it has to be proved for about two years that one cannot be converted to Islam after all, for example in "re-education centres", where those who want to leave are detained. Ultimately, a Sharia court must decide on the resignation - the freedom of religion guaranteed in the constitution exists only in theory. This is also shown by cases from 2007.
Christianity
The Council of Churches of Malaysia is an ecumenical organization representing the Christian churches and affiliated groups in Malaysia. The Christian press can only be published in Malay with difficulty, but is readily available in English, Chinese and Tamil. Unrestricted is the distribution of writings to members of associations or churches. Attempts at censorship (specifically: banning the word "Allah") were made by the government here as well, which was initially overturned by a court, but reintroduced in 2013. In January 2014, the Islamic religious office JAIS made headlines when it entered the premises of the Bible Society of Malaysia without any legal basis and with police support and confiscated 300 copies of the Al-Kitab, the Bible written in Malay.
The building of churches often leads to difficulties with the planning authority in conurbations.
Education

The education system in Malaysia is under the Ministry of Education (Kementerian Pendidikan Malaysia). It is divided into two main departments, of which the Education Sector deals with all matters relating to pre-schools, primary and secondary schools, while the Higher Education Sector is responsible for higher education. Although education policy is the responsibility of the federal government, each Malaysian state has its own Ministry of Education. The legal basis for state education policy is the Education Act 1996.
Malaysia has a public school system that guarantees free, multilingual education for all citizens. In addition, there is the option of attending a private school or participating in homeschooling. Compulsory education is limited to primary level. As in many Asia-Pacific countries, such as South Korea, Singapore and Japan, the curricula and final examinations follow a uniform system across schools.
In 2015, the literacy rate in Malaysia was 94.6% of the adult population. For females, it was 93.2% and for males, 96.2%. In the 2015 PISA ranking, the country's students ranked 45th out of 72 countries in mathematics, 51st in science, and 46th in reading comprehension.
