Why this matters
Before designing a flyer evaluation study for Sara's first physical marketing action — letterbox distribution of an 18×18cm card across Holland Park — we needed to understand who actually lives here. The neighbourhood's demographic profile directly shaped our persona selection, interview design, and the lens through which we interpreted the research findings.
Holland Park is not a typical Dutch neighbourhood. It is one of the youngest, most internationally diverse, and most rental-heavy areas in the Amsterdam metropolitan region. Every one of these characteristics affects how residents process unsolicited post, what "interior design" means to them, and whether Sara's card has any chance of surviving the letterbox.
Population snapshot
Source: AllCharts.info / CBS Kerncijfers Wijken en Buurten 2024–2026
Research implication: Holland Park has nearly tripled in population since 2013 (from 2,033 to 5,815). Most residents are new — they moved here, they didn't grow up here. This means low neighbourhood attachment, limited local networks, and a population still forming its sense of place. A local business card either taps into that forming identity or gets lost in the transience.
Age distribution
Holland Park is overwhelmingly young. Nine out of ten residents are under 45.
Research implication: The dominant segment (25–44, 62%) is precisely the age range most likely to be furnishing a first real home, navigating rental constraints, and balancing design aspirations with budget reality. But 21% are students or early-career (15–24) — a group that categorically self-excludes from "interior design." Our persona set reflected both.
Migration background
Holland Park is one of the most internationally diverse neighbourhoods in the Netherlands. Only 17% of residents have Dutch origins.
70% of all residents were born outside the Netherlands. Among those with non-European origins, the 2022 breakdown (most recent detailed data) shows:
| Origin group | Residents | Notes |
|---|---|---|
| Suriname | 345 | Largest single non-European group |
| Dutch Antilles & Aruba | 160 | |
| Turkey | 115 | |
| Morocco | 85 | |
| Other non-western | 1,200 | Highly diverse — Indian, Chinese, Indonesian, African, South American origins |
Research implication: The word "interior design" carries different cultural weight across these groups. For some, it's an aspirational category; for others, it's an alien luxury concept. The phrase "real homes and real budgets" on Sara's card was specifically designed to bridge this gap — our research tested whether it actually does. The Surinamese-Dutch presence also explained why one persona (Denise Pengel) read "de Abreu" as a recognition signal rather than just a name.
Household composition
Marital status
| Not married | 77% |
| Married | 19% |
| Divorced | 3% |
| Widowed | 0.5% |
Gender split
| Men | 51% (2,920) |
| Women | 49% (2,805) |
Research implication: 61% living alone in an apartment — these are people making solo decisions about their living space, with no partner to consult or share costs. Interior design decisions (and their budget) rest entirely on one person. This is Sara's core audience: the solo renter who wants their space to feel better but doesn't know where to start.
Housing
Virtually all housing is modern apartment stock. There are zero single-family houses, zero terraced homes, zero detached properties. The rental market is dominated by private landlords (82% of all homes) rather than housing corporations (just 1%). 8% of homes are currently uninhabited.
| Ownership type | Count | Share |
|---|---|---|
| Private rental (non-corporation) | 3,207 | 82% |
| Owner-occupied | 665 | 17% |
| Housing corporation | 39 | 1% |
Research implication: 83% renters means 83% of Sara's potential clients face the "renter's dilemma" — wanting to improve their space but constrained by what they're allowed to change. This is exactly the positioning ELI occupies: flexible, non-permanent, budget-conscious improvements. The card's message "real homes" implicitly includes rental apartments, but our research showed this isn't obvious to everyone.
Income and employment
Employment type
Income distribution
46% of households fall in the lowest 40% nationally, while only 13% reach the highest 20%. Median capital assets per household: €7,800. Only 3.5% live at or below the social minimum.
This is a working neighbourhood, not a wealthy one — but not a deprived one either.
Research implication: Average household income of €38,400 means Sara's Room Reset (€80) represents 0.2% of annual income — genuinely accessible. But "interior design" as a category still sounds expensive to people in this income bracket. Our flyer research confirmed this: the single most impactful change to the card would be printing "from €80" — converting an unknown (and therefore frightening) cost into a concrete, manageable number.
Education
790 university students live in the neighbourhood (Campus Diemen-Zuid), alongside 180 HBO students. This contributes to the young demographic skew and the high proportion of single-person households.
Energy and sustainability
Holland Park is one of the most sustainable neighbourhoods in the Netherlands: entirely gas-free, almost entirely on district heating, with 76% of labelled homes at energy label A or above. Car ownership is extremely low at 0.24 per household — residents rely on public transport (Diemen-Zuid station is 500m away), cycling, and shared mobility.
Neighbourhood structure
The borough Holland Park contains four sub-neighbourhoods:
| Neighbourhood | Character |
|---|---|
| Holland Park | Main residential area — modern apartments, shops, restaurants |
| Holland Park West | Western residential extension |
| Holland Park Zuid | Southern section — smallest, 165 residents (2023) |
| Campus Diemen-Zuid | Student housing and campus facilities |
The neighbourhood is compact (48 hectares), highly urbanised (degree 1 — maximum urbanisation), and well-connected: 0.4km to a supermarket, 0.5km to the train station, 0.4km to a GP, 10 minutes to central Amsterdam.
Demographic summary for research design
When we designed the persona set for Sara's flyer evaluation, we needed to represent the population that would actually find the card in their letterbox. The data above pointed us toward six personas spanning:
| Dimension | Holland Park reality | Research representation |
|---|---|---|
| Age | 90% under 45 | 5 personas under 45, 1 older resident (Pieter, 58) as boundary case |
| Origin | 83% immigration background | 4 personas with immigration background (Surinamese-Dutch, Indian expat, Turkish-Dutch, Dutch) |
| Housing | 83% renters, 17% owners | 5 renters, 1 owner-occupier (Elif) |
| Household | 61% single, 29% couples | 3 single, 1 couple, 1 family, 1 student |
| Income | 46% in lowest 40% | Range from student (Bram) to comfortable dual-income (Arjun & Meera) |
| Education | 75% higher education | Mix of HBO, WO, and MBO backgrounds |
The demographic data didn't just inform persona creation — it fundamentally shaped the research questions. In a neighbourhood where 83% of residents have immigration backgrounds, we couldn't assume a shared understanding of "interior design." In a neighbourhood where 83% rent, we couldn't assume people feel entitled to change their space. These constraints became central threads in every interview.
