How Demographics and Supply Data Drive Childcare Site Selection

A childcare site lives or dies on two numbers: how many young children sit inside its catchment, and how many places already compete for them. Get those two right and an average operator can fill a centre. Get them wrong and the best operator in the country cannot. Everything else — the build, the fit-out, the brand on the door — comes after the data has already decided whether the site works.

The Decision Is Made Before You Pour a Slab

Most people choose a childcare development site the way they choose a house: they like the street, the block is the right size, the council looks workable. That is how you end up with a beautifully approved centre that never reaches occupancy.

We look at it the other way around. Before a site is worth a feasibility study, it has to pass a demand-and-supply screen. The land, the zoning, and the development application process only matter once the catchment numbers stack up. A site that fails the screen is not a cheaper opportunity — it is a slower failure.

The Demand Side: Count the Children, Not the People

Population alone tells you almost nothing. A suburb of 30,000 retirees is useless to a childcare operator. What matters is the count of children aged roughly nought to five inside a realistic drive-time catchment, and whether that count is growing.

Three demand signals do most of the work:

• The young-child population in the catchment — typically children aged 0–5, drawn from ABS Census and small-area population data.
• The growth trajectory — new dwelling approvals, land releases, and births tell you whether the catchment is filling with young families or quietly ageing.
• The participation rate — how many of those children actually use formal care. Nationally this has climbed past half: the Australian Government reports that around 50.9% of children aged 0–5 now attend approved care, up from 42.3% in 2016.

Demand is also shifting underneath the data. From 5 January 2026, the 3 Day Guarantee replaced the old activity test, giving every eligible family at least three subsidised days a week regardless of how much the parents work or study. That change pulls a band of lower-activity families back into formal care — and it lands hardest in exactly the outer-suburban and regional catchments where new sites are being considered.

The Supply Side: Map the Competition Honestly

Demand without a supply count is half a picture. The cleanest way to read supply is the places-per-child ratio — the number of approved childcare places in an area divided by the number of children who could use them.

The Mitchell Institute at Victoria University popularised the benchmark that defines a “childcare desert” as an area with fewer than 0.333 places per child — roughly more than three children chasing every place. Their research found that a large share of Australians live in these under-supplied pockets, and that the problem is heavily skewed by geography: access is best in wealthier inner-city suburbs, while outer-suburban, regional, and remote communities carry the highest share of residents in deserts, rising past 60% in outer regional areas.

For a site selector, that ratio cuts both ways. A low places-per-child figure signals genuine undersupply and a faster path to occupancy. A high figure is a warning that the catchment is already saturated, no matter how attractive the block looks.

Then there is the pipeline — the centres not yet open. A catchment can look undersupplied today and be oversupplied in eighteen months once approved-but-unbuilt centres come online. CBRE Research (March 2026) estimated that the sector adds in the order of 30,000 new places a year while losing around 5,000 to closures, against a base-case need of roughly 11,000 net new places annually. Net national growth is real, but it is uneven — which is precisely why a site decision has to be made at the catchment level, not the national one. For the bigger-picture mechanics of how supply and demand interact, see our guide on reading the childcare market.

Turn the Data Into a Decision

Numbers do not select a site. A framework does. The screen we run before recommending a development site comes down to four questions:

1. How many 0–5 children sit inside a genuine catchment — not a postcode, but a realistic 5–10 minute drive in the actual road network and traffic.
2. How many approved places already serve them, and what is the places-per-child ratio today.
3. What is coming — approved, unbuilt, and rumoured centres, plus the dwelling pipeline that will change the child count.
4. Who the families are — income, fee tolerance, and the local socioeconomic profile, which together tell you what fee a centre can actually charge and sustain.

A site that clears all four is rare, and worth moving on quickly. A site that fails the supply test but sits in a growth corridor may still be worth holding — the government’s $1 billion Building Early Education Fund, committed from July 2025 to build and expand around 160 centres in areas of need, is a signal of where official supply is heading, and you do not want to develop into the path of a subsidised competitor.

Where the Data Comes From — and Where It Lies

The raw material is more accessible than most people think. ABS Census and small-area population data give you the child counts and growth. The ABS socioeconomic index (SEIFA) gives you the income and fee-tolerance picture. ACECQA’s national registers tell you which services are approved and where. Commercial area-benchmarking tools layer fees, births, and competitor distances over the top.

But data has blind spots, and they are the ones that cost money. A registered competitor two kilometres away may sit on the wrong side of a river or motorway and be irrelevant to your catchment. A centre that looks open may be running at half occupancy with a poor reputation — an opportunity, not a threat. And a quiet regional town with weak numbers on paper can have a genuine, unmet need that the regional childcare market rewards. The numbers screen the site; local knowledge confirms it. Skip either step and the feasibility study that follows is built on sand.

Key Takeaway

Childcare site selection is a demand-and-supply problem before it is a property problem. Count the children in a real catchment, count the places already competing for them and the ones coming, and only then ask whether the land and the planning work. The site is chosen by the data — your job is to read it before you commit.
