Who Are the Brunei People? Population, Ethnic Categories, and the Capital Explained

By Clara Reyes, Fortrip Editorial. Reyes has reported on Borneo and the Malay Archipelago for regional travel desks since 2015. Figures below are drawn from the sources cited, accessed November 2025, and dated individually where the underlying data is older.

Last updated: November 2025. Population and ethnicity figures from MoFE, the CIA Factbook, and Britannica update on different schedules — this page will be revised when any of those sources publish newer numbers.

Quick answer: Brunei's Ministry of Finance and Economy (MoFE) reported a 2023 population of 450,500, while the CIA World Factbook's 2024 estimate runs as high as 491,900 — a gap that comes from different counting methods, not an error. MoFE's 2023 figures put Malays at 73.8 percent of the population, but that's a legal citizenship category, not a single ethnic group: the 1961 Nationality Act folded seven distinct indigenous peoples into it.

Most articles about Brunei people quote one ethnic percentage and move on. That's a mistake, because the country's own government, the CIA World Factbook, and Britannica's demographic projections don't converge on how many people live there, let alone how to categorize them. Some search for the country as the Kingdom of Brunei, though officially it's Brunei Darussalam, a sultanate on the northern coast of Borneo — not a kingdom, despite the search habit. Understanding Brunei's population means understanding a legal classification system built in 1961, not just reading a pie chart.

How Many People Actually Live in Brunei

Brunei's Ministry of Finance and Economy put the 2023 population at 450,500, up 1.1 percent from 445,400 the year before, according to its Population Estimates Report. The World Factbook's 2024 estimate runs considerably higher, and Britannica's 2026 projection lands in between.

Source	Population estimate	As of	Accessed
Ministry of Finance and Economy, Population Estimates Report	450,500	2023	Nov 2025
CIA World Factbook	491,900	2024	Nov 2025
Britannica, country profile	465,600	2026 projection	Nov 2025

These numbers are presented as each source publishes them. Fortrip has not independently re-surveyed Brunei's population, and readers checking this later should expect the figures to have moved — MoFE updates annually, while the Factbook and Britannica revise their models on their own schedules, which rarely land on the same year.

The gap isn't a mistake on anyone's part. MoFE works from vital statistics and civil registration — births, deaths, visa records, the paperwork a small government actually processes. External estimates from the Factbook and Britannica work from demographic projection, extrapolating forward from older baselines and adjusting for assumed birth and migration rates. Neither method is wrong. They're counting different things at different moments, and Brunei's population is small enough that even modest assumption differences move the headline number by tens of thousands.

What MoFE's 2023 data makes clear is the residency breakdown — close to one in five people physically in Brunei on any given day hold no permanent claim to the place:

Status	Share	Count	As of	Accessed
Citizens	76.0%	342,300	2023	Nov 2025
Permanent residents	5.8%	26,000	2023	Nov 2025
Temporary residents	18.2%	82,200	2023	Nov 2025

That temporary-resident share is largely workers on passes in construction, domestic labor, and the oil and gas sector that still anchors the economy.

What 'Malay' Means on a Brunei Identity Card

The figure most travel write-ups repeat is the Factbook's 2021-based estimate. MoFE's 2023 count differs, and the gap between the two sources is worth laying out directly:

Group	MoFE 2023	CIA Factbook (2021 est.)	Accessed
Malay	73.8% (332,100)	67.4%	Nov 2025
Chinese	9.6% (43,400)	9.6%	Nov 2025
Other	16.6% (75,000)	23%	Nov 2025

Stated this way, it sounds like a straightforward ethnic majority. It isn't, and the two sources disagree by nearly six points on the Malay share alone — a reminder that these are each source's own published figures, not a single reconciled count.

The 1961 Brunei Nationality Act created "Malay race" as a legal category. It does not describe ethnic self-identification. According to ISEAS Perspective research by Chang-Yau Hoon and Asiyah Kumpoh, the act folded seven distinct groups into one citizenship class: Brunei Malay, Tutong, Belait, Dusun, Murut, Kedayan, and Bisaya. A Dusun farmer in Tutong District and a Brunei Malay civil servant in the capital are both "Malay" on paper. They speak different home languages. They come from historically distinct communities. Readers tracking these classification systems across the wider region can find more in Fortrip's Southeast Asia coverage.

The practical consequence is citizenship. Under Minority Rights Group's 2023 documentation, members of these seven groups receive an automatic path to Brunei citizenship, passed through the father. That's a privilege the law does not extend evenly to everyone born in the country.

This legal architecture sits inside a constitutional order shaped after 1959 under Sultan Omar Ali Saifuddien III, whose name the capital itself now carries — Bandar Seri Begawan was called Brunei Town until 1970, when it was renamed in his honor, according to Wikipedia's 2025 entry.

The Indigenous Brunei People the 'Malay' Category Leaves Out

Not everyone indigenous to Brunei fits inside the seven-group Malay classification. Iban and Penan communities are recognized as indigenous peoples of Brunei, concentrated mostly near the Sarawak border, but they sit outside that 1961 framework entirely.

Citizenship: A Harder Path for Iban and Penan

The citizenship asymmetry is concrete, not theoretical. Minority Rights Group's 2023 documentation shows that while the seven "Malay race" groups get automatic citizenship through the father, Iban and Penan applicants face a two-parent requirement. Both parents must qualify. That's a materially harder bar to clear.

Older estimates from the World Directory of Minorities and Indigenous Peoples, published by Minority Rights Group International in 2008, put Dusun at roughly 6.3 percent of the population, Murut at around 6 percent, and Iban at roughly 4.7 percent; the Penan numbered fewer than 300 individuals total at the time. These figures are seventeen years old as of this writing. Brunei's own census and MoFE reports do not break ethnicity down below the aggregated Malay/Chinese/Other categories, so there is no official, more recent disaggregation to update against — the 2008 estimate remains the most recent publicly available breakdown Fortrip could locate, and it should be read as directional rather than current.

Religion and Identity Inside the Classification

Religion compounds the distance. The same ISEAS Perspective research describes how many Iban and Penan retain non-Muslim identities. That sits awkwardly against Brunei's official framing as a Malay Islamic Monarchy — a state ideology where ethnicity, religion, and governance are formally braided together. The same research also describes animist practices surviving among some indigenous communities classified as Malay, alongside rather than replaced by Islamic identity. That's a gap between legal category and lived culture that the classification system doesn't track. This pattern reappears later in the religion figures below, rather than being a separate phenomenon.

Bandar Seri Begawan: How Big Is the Capital, Really

Bandar Seri Begawan's municipal population, per Wikipedia's 2025 estimate, is 72,133 people across 100.36 sq km. That's small enough that first-time visitors often mistake it for a large town rather than a national capital — there's no skyline to speak of, and the center can be walked in an afternoon.

Area definition	Population	Source	Note
Municipal boundary	72,133	Wikipedia, 2025	Dated estimate
Built-up urban area	180,000–200,000	Expat.com guide	Rough third-party estimate, undated

The built-up figure is the one that explains the traffic on Jalan Tutong during morning commute hours and the steady housing demand near the city center, even though it's a looser estimate than MoFE's district-level data. If you're mapping a route through the capital's stilt-house neighborhoods and the Temburong Bridge crossing, Fortrip's itinerary validator checks that kind of logistics before you land.

The capital sits on the Brunei River in Brunei-Muara District, which MoFE's 2023 data shows held 326,000 people — 72.4 percent of the national total, by far the most of Brunei's four districts. It's the seat of Sultan Hassanal Bolkiah's government and has been the administrative center since well before the 1970 renaming.

Kampong Ayer: The Brunei People Living on the River

Source	Estimate	Note
Tourism and local guides (commonly cited)	~30,000 residents	Rough third-party estimate; no official census breakout; undated

That figure doesn't come from a single verified census return. It's the number repeatedly used in descriptions of the water village, and it should be read as a widely cited estimate rather than an official count. What's not in dispute is that this is a functioning neighborhood with schools, clinics, and mosques built on stilts over the water, and water taxis that residents use the way other cities use buses or the subway. This is life in Brunei Darussalam at ground level, not a staged backdrop.

Tour itineraries tend to frame Kampong Ayer as a photo stop, something you pass through on a river tour and leave. That framing misses the point. Families here have raised children across generations in the same stilt houses. If you're sketching a route through the capital, it's worth treating Kampong Ayer as a place people live rather than a cultural exhibit scheduled between breakfast and the mosque visit — an AI trip planner can help structure a day that gives it that weight instead of ten rushed minutes.

Brunei's Land Area, Districts, and the Temburong Problem

Brunei's total land area is 5,765 sq km (2,226 sq mi), according to Britannica's 2026 country profile, split across four districts: Brunei-Muara, Tutong, Belait, and Temburong. Britannica's 2026 projection estimates a national density of 80.8 persons per sq km, though that average hides a lopsided distribution of Brunei people across the territory.

Temburong is the outlier. It's physically separated from the other three districts by Malaysian Sarawak, which cuts straight through the middle of the country's territory. For decades, the only way to reach Temburong was by boat along the coast or river. The Temburong Bridge changed that, connecting it by road to Brunei-Muara for the first time.

The geography explains the population imbalance. With 72.4 percent of the national population concentrated in Brunei-Muara around the capital (MoFE, 2023), Temburong sits nearly empty by comparison — mostly rainforest, a small administrative center, and a fraction of the people found in the capital district alone.

Is Brunei Religiously Uniform

Islam is the official religion under the Malay Islamic Monarchy concept. That's the constitutional ideology that also shapes how ethnicity and citizenship are defined. The World Factbook's 2021-based estimate, accessed November 2025, puts the population at:

• Muslim: 82.1%
• Christian: 6.7%
• Buddhist: 6.3%
• Other: 4.9%

"Majority" isn't "uniform." Christianity is practiced among some indigenous and Chinese Bruneian communities. Buddhism is concentrated among parts of the Chinese population. Animist practices persist within some communities classified as Malay, as the earlier section on Iban, Penan, and Dusun communities laid out. These practices run alongside Islamic identity rather than replacing it. The pattern repeats the one the ethnic classification produces: an official category — Malay, Muslim — that's accurate as a majority description and incomplete as a full account of who lives in the country.

Frequently Asked Questions

How many people live in Brunei?

Brunei's Ministry of Finance and Economy reported 450,500 people in its 2023 Population Estimates Report. The CIA World Factbook's 2024 estimate puts the figure at 491,900, and Britannica's 2026 projection lands at 465,600. The gap reflects different counting methods — civil registration versus demographic modeling — not a disputed fact.

What ethnic groups make up Brunei?

MoFE's 2023 data groups the population as 73.8 percent Malay, 9.6 percent Chinese, and 16.6 percent other. But "Malay" is a legal category created by the 1961 Nationality Act, folding seven groups — Brunei Malay, Tutong, Belait, Dusun, Murut, Kedayan, and Bisaya — into one citizenship class. Iban and Penan communities are recognized as indigenous but fall outside this classification.

How many people live in Kampong Ayer?

Tourism and local guides commonly cite roughly 30,000 residents in Kampong Ayer's stilt-house settlements. This is a widely repeated estimate rather than a dated official count, since Brunei's census data doesn't break the water village out as a separate figure.

What is Bandar Seri Begawan's population?

Within its municipal boundary, Bandar Seri Begawan has 72,133 residents as of a 2025 estimate. The functional urban area — including surrounding neighborhoods that operate as part of the same city — is estimated at 180,000 to 200,000 by an expat guide, though that range is a rough, undated third-party figure rather than an official count.

Who Counts as a Brunei Person Today

Put the pieces together and "Brunei people" stops being a single demographic answer. There are citizens classified under the seven-group Malay category created by the 1961 Nationality Act. There are non-Malay indigenous peoples — Iban, Penan — who face a harder citizenship bar despite being just as indigenous to the territory. And there's a temporary-resident population, 18.2 percent of everyone counted in the country as of 2023, that keeps the economy running without holding permanent status. The Brunei nation, in other words, is built from overlapping legal categories, not a single ethnic story.

That's the layered legal and social system most competing articles miss when they quote one Factbook percentage and stop. For a sense of what planning this kind of trip costs against doing it manually, the plans breakdown lays out the trade-off in plain terms — useful context for anyone extending the trip into neighboring Sarawak and Sabah after Brunei.
