Mobile Advertising Across Hong Kong's 18 Districts: Population and Density Planning Guide (2026)

“Which district delivers the most impressions?” Population alone cannot answer that. Census and Statistics Department data put Kwun Tong's density at nearly 60,000 residents per km², compared with about 7,000 citywide. Yet Central and Western, with only about 236,000 residents, contains some of Hong Kong's most expensive advertising locations.Residential population and daytime population are different measures.This guide uses official figures to explain how to choose districts.

Key takeaways

Highest density: The Census and Statistics Department identifies Kwun Tong as the most densely populated district, with nearly 60,000 residents per km², versus a Hong Kong average of about 7,000.
Largest populations: Population and Household Statistics Analysed by District Council District puts the 2024 land-based non-institutional population at 7,432,500, with Sha Tin, Yuen Long and Kwun Tong having the largest district populations。
Lowest density: Islands has the lowest density, at around 1,021 people per km².
Key distinction: Residential density helps assess community reach. Commercial daytime footfall also comes from commuters: Central and Western has around 236,000 residents and Wan Chai around 167,000, far fewer than Kwun Tong's approximately 673,000.
Change over the decade: Planning Department projections for 2021–2031 show Islands' share of Hong Kong's population rising from 2.5% to 4.5%, North from 4.2% to 5.6% and Yuen Long from 9% to 9.7%. Yau Tsim Mong falls from 4.2% to 3.4%, Eastern from 7.1% to 6.0% and Sha Tin from 9.3% to 8.5%.
No common public street-impression audit: Hong Kong has no shared, publicly audited industry standard for OOH impressions. A supplier's district-level estimate depends on its own measurement method.

1. Residential density is not the same as advertising exposure

Residential and daytime populations differ

Official population and density figures describe the resident population. They show where people live and how densely, but not how many people are on a street during the day. In Hong Kong, the distinction is substantial:

Central and Western District Around 235,953 residents across 12.55km², or about 18,808 people per km²—a middle-ranking density among the 18 districts. Yet it contains some of the most expensive commercial advertising sites because of its daytime office-worker influx.
Wan Chai District Around 166,695 residents, among the smallest district populations, yet Causeway Bay is a major shopping destination.
Kwun Tong District Around 673,166 residents and about 59,704 people per km²: a large population and the highest district density, while billboard prices are generally below Central and Causeway Bay.

Use residential population and density for neighbourhood campaigns. For commercial districts, examine business activity and commuting flows; these do not have an equivalent, comprehensive public street-level measure.

Hong Kong has no common public street-footfall audit

The UK has Route and the US has Geopath for third-party OOH audience measurement. Hong Kong has no single shared, publicly audited industry standard, and media owners report reach on different bases.When a supplier claims hundreds of thousands of daily impressions in a district, ask about the method, sampling period and treatment of repeat exposure.

Our approach is to use verifiable official population data as the foundation, identify commercial-area and timing recommendations as operating judgement, and suggest ways to check them yourself.For a complete measurement framework, see Public case studies and data provenance。

2. Official population, area and density figures for the 18 districts

Citywide reference points

Keep two reference figures in mind: Hong Kong's average density is about 7,000 people per km²; its 2024 land-based non-institutional population was 7,432,500. Compare district density against the average, while keeping the different reference years in view.

Hong Kong Island: four districts

District Council district	Population (2021)	Area (km²)	Density (people/km²)
Central and Western District	235,953	12.55	18,808
Wan Chai District	166,695	10.64	15,791
Eastern District	529,603	18.13	29,440
Southern District	263,278	39.40	6,779
Hong Kong Island subtotal	1,195,529(16.1% of Hong Kong's population)	80.72(7.30% of land area)	14,957

Campaign implication: Hong Kong Island accounts for about 16.1% of residents but includes the most expensive commercial advertising locations, illustrating the role of daytime commuters. Southern's density, about 6,779, is below the citywide average; its lower-density residential and tourist areas need more selective routes.

Kowloon's five districts: the densest region

District Council district	Population (2021)	Area (km²)	Density (people/km²)
Yau Tsim Mong District	310,647	6.99	44,458
Sham Shui Po District	431,090	9.36	46,067
Kowloon City District	410,634	10.02	40,994
Wong Tai Sin District	406,802	9.30	43,730
Kwun Tong District	673,166	11.27	59,704(highest in Hong Kong)
Kowloon subtotal	2,232,339(30.1% of Hong Kong's population)	46.94(4.24% of land area)	47,557

Campaign implication: this comparison is particularly useful.Kowloon contains 30.1% of Hong Kong's population on 4.24% of its land area. Its overall density is about 47,557 people per km²—nearly seven times the citywide average.A short route can therefore pass through areas with a large resident population, although actual street exposure still depends on the route and time.Kowloon's five districts offer strong potential for efficient neighbourhood coverage.

Kwun Tong alone approaches 60,000 residents per km², the highest district density. This supports community campaigns in Kowloon East. Its expanding office areas also bring daytime workers, giving selected streets both residential and business audiences.

The New Territories: nine districts with wide density differences

District Council district	Population (2021)	Area (km²)	Density (people/km²)
Kwai Tsing District	495,798	23.34	21,246
Tsuen Wan District	320,094	62.62	5,168
Yuen Long District	668,080	138.56	4,825
Tuen Mun District	506,879	84.76	5,908
North District	309,631	136.53	2,269
Tai Po District	316,470	148.18	2,325
Sha Tin District	One of the three largest land-based non-institutional populations, alongside Yuen Long and Kwun Tong
Sai Kung District	About 6.6% of Hong Kong's population in the Planning Department's 2021 projection baseline
Islands District	Lowest population density, around 1,021 people per km²
New Territories subtotal	53.8% of Hong Kong's population; more than 53.8% of land area

Campaign implication: broad district coverage can be inefficient.Yuen Long has around 668,080 residents across 138.56km², a density of only about 4,825 people per km². Residents cluster in town centres while large areas are rural. North and Tai Po are even less dense, at around 2,269 and 2,325 respectively.

Trying to “cover the whole district” is rarely a useful New Territories objective . Target town centres and estate clusters, or much of the day will be spent in low-density areas. Kwai Tsing, at about 21,246 people per km², is relatively compact. For route-planning methods, see Routes, Timing and Coverage Strategies。

Three figures to remember

Highest district density: Kwun Tong(about 59,704 people per km²), compared with about 47,557 across Kowloon and 7,000 citywide.
Three largest populations: Sha Tin, Yuen Long and Kwun Tong(Census and Statistics Department, 2024).
Lowest density: Islands(about 1,021 people per km²), followed by North at around 2,269 and Tai Po at around 2,325 in the cited comparisons.

3. Three types of campaign area

Type 1: Central commercial districts—Central and Western, Wan Chai, Yau Tsim Mong

Characteristics: Resident populations are relatively modest—about 236,000 in Central and Western, 167,000 in Wan Chai and 311,000 in Yau Tsim Mong—but commuter and shopper activity is substantial. Yau Tsim Mong is also densely residential, at around 44,458 people per km².

Planning approach: Prioritise useful hours over the day count. Office-worker opportunities may concentrate in roughly four hours around lunch and the evening commute; plan the eight- or nine-hour shift around these windows. Published agency billboard averages include about HK$170,000 in Central, HK$130,000 in Causeway Bay and HK$65,000 in Mong Kok, subject to the quoted format and term.

Practical constraint: Many central streets have stopping restrictions, so the vehicle mainly circulates. A suitable option is an LED advertising truck, with distance visibility and a strong evening presence.

Type 2: Dense residential areas—Kwun Tong, Sham Shui Po, Wong Tai Sin, Kowloon City, Eastern and Kwai Tsing

Characteristics: Densities are several times the Hong Kong average: about 59,704 in Kwun Tong, 46,067 in Sham Shui Po, 43,730 in Wong Tai Sin, 40,994 in Kowloon City, 29,440 in Eastern and 21,246 in Kwai Tsing.

Planning approach: strong potential for efficient community campaigns.Compact residential areas let a short route reach neighbourhoods repeatedly over several days. A suitable option is a Mini promotional truck . Older streets and estate access roads may be unsuitable for large vehicles. Our mini promotional truck carries up to 1,000kg and includes solar power and Wi-Fi, supporting distribution campaigns.

Timing: Morning departures, evening returns and weekend shopping. For practical approaches, see Advantages of mini promotional trucks and A practical three-day store-opening plan。

Type 3: Lower-density areas and new towns—Yuen Long, Tuen Mun, Tsuen Wan, North, Tai Po, Southern, Sai Kung and Islands

Characteristics: Total populations can be large—around 668,000 in Yuen Long and 507,000 in Tuen Mun—while density remains low: about 4,825 in Yuen Long, 5,908 in Tuen Mun, 5,168 in Tsuen Wan, 6,779 in Southern, 2,269 in North, 2,325 in Tai Po and 1,021 in Islands.

Planning approach: target town centres rather than whole districts.Residents concentrate in new-town centres and estate clusters; much of the surrounding land is rural or country park. Build two or three short loops around shopping centres, MTR stations and main estate entrances, switching by time slot rather than making one large circuit.

Comparing the three area types

Area type	Density pattern	Potential efficiency per kilometre	Suggested vehicles	Main time slots
Central commercial districts	Smaller resident population; larger daytime audience	Time-dependent, strongest around lunch and the evening commute	LED advertising truck	Weekday lunch and after work
Dense residential areas	Several times the citywide residential density	High potential	Mini promotional truck	Morning, evening and weekends
Lower-density new towns	Large but geographically dispersed populations	Higher around town centres	Depends on the area; focus on its core	Weekend daytime

4. Population-share projections to 2031

For annual or longer-term planning, consider the Planning Department's projected changes in district shares of Hong Kong's population:

District Council district	Share in 2021	Projected share in 2031	Trend
Islands District	2.5%	4.5%	Largest increase
North District	4.2%	5.6%	Substantial increase
Tuen Mun District	6.8%	7.5%	Increase
Yuen Long District	9.0%	9.7%	Increase
Sai Kung District	6.6%	6.9%	Small increase
Kowloon City District	5.5%	5.9%	Small increase
Tai Po District	4.3%	4.4%	Stable
Kwun Tong District	9.1%	8.8%	Small decrease
Sham Shui Po District	5.8%	5.6%	Small decrease
Wong Tai Sin District	5.5%	5.1%	Decrease
Tsuen Wan District	4.3%	3.8%	Decrease
Kwai Tsing District	6.7%	6.2%	Decrease
Sha Tin District	9.3%	8.5%	Decrease
Southern District	3.6%	3.4%	Decrease
Central and Western District	3.2%	2.8%	Decrease
Eastern District	7.1%	6.0%	Larger decrease
Yau Tsim Mong District	4.2%	3.4%	Larger decrease
Wan Chai District	2.2%	1.9%	Decrease

The regional shift is also clear: Hong Kong Island falls from 16.1% to 14.1%, Kowloon from 30.1% to 28.8%, while the New Territories rises from 53.8% to 57.1%. New towns rise from 48% to 49.3%.

Three implications for campaign planning

The northwestern New Territories and Islands are growth areas in the projections.Islands' share rises from 2.5% to 4.5%, the largest change, while North rises from 4.2% to 5.6%. These areas merit consideration for long-term community branding, with local costs and audience growth checked before booking.
Kowloon and Hong Kong Island lose residential population share, while retaining important commercial functions. Their campaign value may increasingly depend on daytime business activity rather than residential reach alone.
Sha Tin's share falls from 9.3% to 8.5%, yet it remains among the largest districts in the cited population figures.Distinguish absolute population from percentage share: a falling share does not make a district small.

5. The same district offers different audiences at different times

Four time slots and their characteristics

Time	Audience characteristics	Most suitable area types	Considerations
Morning (about 7:30–9:30am)	Dense footfall, but people are rushing	Dense residential areas	Many hire packages begin at 10am, so this may be unavailable
Lunch (around noon–2pm)	Slower walking pace and more attention to the street	Central commercial areas and Kwun Tong	One of the better periods for viewing time
After work to dinner (around 6–8pm)	Peak footfall	Commercial and residential areas	Some roads prohibit stopping from 5–7pm
Evening (around 8–10pm)	Lower density but more concentrated attention	Shopping and dining districts	LED visibility is strongest; respect noise controls in residential areas

A free way to check time slots

Compare Google Maps Popular Times for five to ten target venues to see when relative activity peaks. The busiest period may be an hour or two earlier or later than expected. This is a useful free cross-check, but venue popularity is not a street-level impression count.

Two definitions of a rental “day”

Before scheduling, check the supplier's terms. Some provide eight hours within 10am–10pm; others provide nine hours starting on arrival at the target location, excluding the outward journey.For distant New Territories locations, that distinction may change useful campaign time by one or two hours.Overtime is commonly about HK$200–300 an hour. For details, see Mobile billboard hire costs 2026: rates and quote breakdown。

6. Road restrictions that shape the route

Places where stopping is prohibited

The Road Users' Code lists locations where drivers must not stop, even to load or unload, including expressways, active no-stopping zones, zebra or light-controlled crossings, bus/minibus stops, taxi stands and tunnel/control areas. Signpost colours provide a reference: red: 7am–midnight; yellow: 7am–7pm; green: 8–10am and 5–7pm; grey: other hours . Colours are only a guide; the actual restriction sign takes precedence.

Green-post restrictions include 5–7pm, a prime evening-commute window, so plan to circulate rather than stop on those roads during the restricted period.

School-area restrictions

The Road Users' Code also identifies school entrances and nearby areas as places where drivers should not stop, even to pick up or set down pupils, as well as locations near school crossing patrols. Family campaigns should pass safely along nearby roads or use lawful parking, without obstructing traffic or stopping at school gates.

Sound restrictions in residential areas

Under section 5(1)(b) of the Noise Control Ordinance (Cap. 400), amplified sound in domestic premises or a public place that causes annoyance amounting to a nuisance can be an offence at any time. Vehicle-mounted speakers are included. The provision does not specify a single acceptable decibel ceiling.

Stationary displays need a suitable venue

Most central streets do not permit extended stops. Arrange displays at shopping centres, private property, event venues or government land with the necessary District Lands Office approval. Obtain written owner or management permission for private sites. For more, see Twenty frequently asked questions about mobile promotional vehicles。

7. Choose areas around your objective

Objective: neighbourhood awareness and new-store visits

Prioritise dense residential areas. Kowloon's five districts average about 47,557 people per km²—nearly seven times the citywide average—on 4.24% of Hong Kong's land. Kwun Tong (59,704), Sham Shui Po (46,067), Wong Tai Sin (43,730) and Kowloon City (40,994) offer compact community routes. Repeat a suitable mini-truck loop over several days to build familiarity.

Objective: business and B2B audiences

Target daytime commercial activity in Central and Western, Wan Chai, Yau Tsim Mong and selected Kwun Tong office areas. Schedule the eight- or nine-hour shift around lunch and evening-commute windows, using LED visibility where appropriate.

Objective: families and weekend shoppers

Choose new-town centres rather than entire districts. Sha Tin, Yuen Long and Tuen Mun have large populations; Sha Tin and Yuen Long join Kwun Tong among the three largest in the 2024 figures. Yuen Long has about 668,000 residents and Tuen Mun about 507,000 in the cited baseline. Focus weekend daytime routes on shopping centres, MTR stations and major estate entrances.

Objective: long-term brand building over three years or more

Consider projected growth areas. Population shares rise from 2.5% to 4.5% in Islands, 4.2% to 5.6% in North, 6.8% to 7.5% in Tuen Mun and 9.0% to 9.7% in Yuen Long. These warrant early consideration for local brand awareness, subject to actual development, current audience data and quotations.

Objective: Hong Kong-wide awareness

Avoid dividing the budget equally among 18 districts. A more practical network can concentrate on Kowloon's five districts, with 30.1% of residents, plus Sha Tin, Yuen Long, Tuen Mun and Kwai Tsing. This covers a large share of the population with less unproductive transfer time. For industry applications, see Mobile Promotion Across 10 Industries。

8. Five district-selection mistakes

Mistake 1: treating residential density as impressions

Density describes residents. Central and Western at around 18,808 people per km² and Wan Chai at around 15,791 are less dense than Kowloon's five districts, yet include premium advertising sites because commuters are not captured by resident counts.Use density for community planning and daytime activity for commercial exposure.

Mistake 2: trying to cover an entire New Territories district

Yuen Long spans 138.56km² at about 4,825 people per km²; North 136.53km² at about 2,269; and Tai Po 148.18km² at about 2,325. Residents cluster in town centres, with rural land elsewhere.A broad “cover Yuen Long” brief can waste substantial driving time.

Mistake 3: splitting the budget equally across all 18 districts

This can dilute repeated exposure in every area. Two to four neighbouring commercial areas per vehicle per day is often more practical; long transfers consume time with limited relevance to the target audience.

Mistake 4: ignoring the difference between population size and share

Sha Tin's share falls from 9.3% to 8.5% but it remains a major population centre. Islands rises from 2.5% to 4.5% from a smaller base and has a cited density of only about 1,021.Use current population and density for near-term campaigns, and projections for longer-term planning.

Mistake 5: accepting impression estimates without a method

Without a shared public OOH audit standard, supplier estimates may not be comparable. Ask about the method, sampling period and repeat contacts. Countable on-site activity and trackable responses provide firmer campaign evidence.

9. Frequently asked questions

Which Hong Kong district has the highest population density?

Kwun Tong. The Census and Statistics Department describes nearly 60,000 residents per km², well above the citywide average of about 7,000. The cited 2021 comparison gives around 673,166 residents, 11.27km² and 59,704 people per km². Other high-density districts include Sham Shui Po (46,067), Yau Tsim Mong (44,458), Wong Tai Sin (43,730) and Kowloon City (40,994). Kowloon overall averages about 47,557, nearly seven times the Hong Kong average.

Which districts have the largest populations?

The Census and Statistics Department's 2024 district report gives a land-based non-institutional population of 7,432,500, with Sha Tin, Yuen Long and Kwun Tong the largest districts. The cited 2021 population figures include Kwun Tong 673,166, Yuen Long 668,080, Eastern 529,603, Tuen Mun 506,879 and Kwai Tsing 495,798. Population size and density differ: Yuen Long spans 138.56km² at about 4,825 people per km², with residents concentrated around its town centres.

Does higher population density mean more advertising impressions?

No. Residential figures help assess community potential, not daytime street audiences. Central and Western has around 235,953 residents at about 18,808 per km², and Wan Chai around 166,695 at about 15,791. Both are less dense than Kowloon's five districts but attract substantial commuter activity and premium commercial advertising. Use residential data for neighbourhood planning and business activity and commuter flows for commercial routes; neither alone measures actual impressions.

Which areas suit neighbourhood campaigns?

Dense residential areas offer compact routes. Kowloon's five districts average about 47,557 people per km², nearly seven times the citywide 7,000, on 4.24% of the land. Examples include Kwun Tong (59,704), Sham Shui Po (46,067), Wong Tai Sin (43,730), Kowloon City (40,994), Eastern (29,440) and Kwai Tsing (21,246). Smaller vehicles can suit older streets and estate access, subject to access restrictions. Repeat selected routes around morning, evening and weekend activity.

What matters when planning in the New Territories?

Focus on town centres and estate clusters rather than whole districts. The cited areas and densities include Yuen Long 138.56km²/4,825 people per km², Tuen Mun 84.76km²/5,908, Tsuen Wan 62.62km²/5,168, North 136.53km²/2,269 and Tai Po 148.18km²/2,325. Islands has the lowest density, around 1,021. Much of the land is rural or country park. Use two or three short loops around shopping centres, MTR stations and main estate entrances, changing by time slot.

Which districts are projected to grow through 2031?

The Planning Department's 2021–2031 projections show rising population shares in Islands (2.5% to 4.5%), North (4.2% to 5.6%), Tuen Mun (6.8% to 7.5%), Yuen Long (9.0% to 9.7%), Sai Kung (6.6% to 6.9%) and Kowloon City (5.5% to 5.9%). Shares fall in Yau Tsim Mong (4.2% to 3.4%), Eastern (7.1% to 6.0%) and Sha Tin (9.3% to 8.5%). Regionally, Hong Kong Island falls from 16.1% to 14.1%, Kowloon from 30.1% to 28.8%, and the New Territories rises from 53.8% to 57.1%. Treat these as projections when planning long-term local branding.

Should I focus on one district or spread across several?

It depends on the objective, but equal spending across 18 districts can dilute repeat exposure. For local visits or a new store, repeat routes in the target neighbourhood. For broader awareness, consider a network of population centres: Kowloon's five districts account for 30.1% of residents, with Sha Tin, Yuen Long, Tuen Mun and Kwai Tsing adding substantial reach potential. Two to four adjacent commercial areas per vehicle per day is often more practical than long transfers.

What are the best campaign hours?

Commercial areas often favour weekday lunch, around noon–2pm, and the evening commute, around 6–8pm. Residential areas favour morning/evening travel and weekends; shopping areas favour weekends and holidays; dining and entertainment areas favour evenings. Check service hours, as some rentals start at 10am and exclude the morning commute. Green-post stopping restrictions can cover 5–7pm, so circulate rather than stop where applicable. Google Maps Popular Times can help cross-check local timing, but is not an impression count.

Can a campaign stop outside a school?

Do not plan stops at school entrances or nearby crossing patrols. The Road Users' Code identifies these as places where drivers should not stop, even for pupils. Pass safely along appropriate nearby roads or use lawful parking without blocking traffic. A display inside school grounds requires advance written permission from the school.

Can I trust a claim of hundreds of thousands of daily district impressions?

Ask how it was measured. Hong Kong has no single shared, publicly audited OOH audience standard comparable across all suppliers; the UK has Route and the US has Geopath. Ask which footfall data were used, the sampling period, and how repeat contacts and obstructed views are treated. Require route logs and on-site photos/videos to verify delivery, and use a campaign-specific QR code or offer code to track responses.
