Slide 1: From Data to Design: Planning Melbourne’s Future

Melbourne City

By 2043, Melbourne’s population is expected to climb from 354,801 to 584,262 people—an increase of around 229,000 residents in two decades (City of Melbourne Population Forecasts, 2023-2043).

This project turns open data into insight, tracking Melbourne’s growth using four clear indicators, such as People, Housing, Jobs, and Access. The plan smarter for a sustainable and inclusive future.

Slide 2: A City Growing by Design

Slide 2 of 10

Between 2023 and 2043, the city’s population is forecast to expand from 354,801 to 584,262, adding +229,461 residents, representing a 2.53% compound annual growth rate (CAGR) (City of Melbourne Population Forecasts, 2023–2043).

The line chart here traces that steady upward curve, shows that growth is both consistent and cumulative. Each data point marks thousands of new residents, homes, building layer upon layer of urban transformation.

This slide sets the foundation for what follows: understanding not only how much Melbourne will grow, but where and in what form that growth will take. According to urban planning principles discussed by Kirk (2012), seeing the “big picture” first allows us to frame a clear narrative before diving into the details — a vital step in visual storytelling.

In the next slides, we zoom in from this macro trend to explore the people, the places, and the professions shaping Melbourne’s path to 2043.

Slide 3: A Changing City of People

Slide 3 of 10

Melbourne’s population is projected to grow from 354,801 in 2023 to 584,262 by 2043 — an increase of 229,461 people in just two decades. The 25–39 age group remains dominant, rising from 159,915 (45.1%) to 247,573 (42.4%), while the 60+ group grows from 33,758 (9.5%) to 47,490 (8.1%). Both increase in number but decline slightly in share, reflecting a broader, more balanced age mix.

Gender proportions are also stable. In 2023, there were 180,304 females and 174,497 males, a difference of 5,807 people. By 2043, the gap widens slightly to 8,014, with females comprising 50.7% of the population. The ratio remains close to 49:51, showing a balanced demographic profile.

Overall, Melbourne’s population growth is youthful, diverse, and gender-balanced. This shows a strong workforce base for the decades ahead. The next slide explores where this expansion will occur and which neighbourhoods will grow fastest

Slide 4: Where Melbourne Will Grow Fastest

Slide 4 of 10

This slide highlights the Top 10 areas in Melbourne by dwelling growth rate (2023–2040). Data from the City of Melbourne’s Dwellings Forecasts show that growth is concentrated in a few key inner suburbs.

North Melbourne leads the ranking with an impressive 47.3% increase, adding more than 4,400 new dwellings. This rapid growth is largely driven by the Arden Precinct redevelopment, which will bring new housing, jobs, and transport links through the Metro Tunnel – Arden Station (opening 2025). West Melbourne (Residential) and Kensington follow with growth rates above 30%, reflecting strong urban renewal along Melbourne’s western corridor.

Meanwhile, Melbourne (CBD) continues to expand (+7,360 dwellings, 19.3%), while Southbank and Docklands sustain steady high-density development. Outer areas such as Carlton, South Yarra, and East Melbourne record more moderate growth under 10%, indicating maturity and limited redevelopment potential.

Slide 5: The Future of Work

Slide 5 of 10

A growing city needs more than homes — it needs jobs that match its people. By 2040, employment in Melbourne consolidates around three main clusters: Knowledge, Service, and Industrial sectors.

The data show that Business Services lead the city’s workforce, followed by Finance & Insurance, Healthcare & Social Assistance, and Public Administration — all part of the Knowledge economy. Together, they account for nearly 40% of total employment, driven by Melbourne’s expanding professional base and its role as a national business hub.

Service-oriented sectors such as Food & Beverage, Retail Trade, and Accommodation remain vital for daily urban life, providing thousands of jobs across hospitality, tourism, and retail. Meanwhile, Industrial sectors — including Transport, Postal & Storage and Utilities — continue to modernise but now form a smaller share of the total.

Slide 6:Employment Outlook to 2043

Slide 6 of 10

Melbourne’s economy is changing shape. By 2040, the Knowledge Economy dominates, accounting for ≈40% of all jobs. Within it, Business Services (15–18%), Finance & Insurance (12–15%), and Healthcare & Social Assistance (10–12%) emerge as the city’s largest employers. These sectors grow rapidly, driven by population expansion, ageing demographics, and Melbourne’s role as a national corporate hub.

The Service Economy follows with ≈33% of employment, led by Food & Beverage (8–10%) and Retail Trade (6–8%). Growth here stabilises after 2035 as markets mature. Meanwhile, Industrial sectors—including Transport, Utilities, and Manufacturing—continue to shrink, now representing only ≈13% of total jobs.

The interactive line chart reveals these trajectories clearly: clicking a sector highlights its trend while others fade, following Few’s (2006) visual emphasis principle.

Overall, Melbourne is transitioning from factory floors to office towers — from production to innovation — powered by people, skills, and ideas rather than land or machinery

Slide 7: Spatial Distribution

Slide 7 of 10

The Growth Map: A Spatial Overview

Here the growth story becomes spatial. Each circle shows where dwellings will expand and how quickly:

Size = absolute growth in homes
Color = growth rate (%)

Large, warm-toned circles signal areas growing both in volume and speed—places where we’ll feel the change on the ground.

Growth in Melbourne is not uniform — it clusters in strategic zones shaped by infrastructure, planning policy, and market demand. This spatial logic reflects a deliberate strategy: concentrate density where transport and services already exist.

The map reveals three clear growth patterns:

  • Inner Core (CBD, Southbank, Docklands): Large, warm-toned bubbles mark the highest absolute growth, driven by vertical living and proximity to jobs, transit, and amenities.

  • Western Growth Corridor (North Melbourne, West Melbourne, Kensington): Red bubbles show the fastest growth rates, fuelled by the Arden Precinct redevelopment and new Metro Tunnel – Arden Station (opening 2025). These areas are transitioning from industrial heritage to high-density, mixed-use precincts.

  • Established Inner Suburbs (Carlton, South Yarra, East Melbourne): Smaller, cooler-toned bubbles signal steady but moderate growth, constrained by heritage and built character.

Melbourne’s growth is infrastructure-led and transit-oriented, concentrating density around the CBD and major transport nodes — boosting accessibility and efficiency while preserving the charm of established neighbourhoods

Slide 8: The Rise of Vertical Living

Slide 8 of 10

How will Melbourne’s new residents live? The answer is clear — vertically.

Across the Top 8 growth areas, apartments dominate the housing mix, ranging from 60 % in Carlton to nearly 100 % in Southbank, CBD, and Docklands. This reflects deliberate planning policy that channels density toward transport corridors and job centres, reducing urban sprawl while maximising land efficiency.

Three Housing Patterns Emerge:

  • Pure High-Rise Zones (90–100 % apartments): North Melbourne, Southbank, CBD, and Docklands deliver vertical density on compact sites near metro and tram networks.

  • Mixed-Form Precincts (60–85 % apartments): West Melbourne, Kensington, and Carlton retain heritage townhouses and detached homes, creating visual and social diversity.

  • Design Challenge: When almost all new dwellings are apartments, urban design quality becomes critical. Residents need public open space, active ground floors, and well-designed buildings to sustain daily life.

Melbourne’s future housing form is apartment by necessity but liveability by design — the success of growth will depend not only on how high we build, but on how well we design for people

Slide 9: Investment Dashboard

Slide 9 of 10

Where should investment and planning focus next? This dashboard brings four key metrics together — Population Growth (35%), Jobs Diversity (25%), Housing Mix (25%), and CBD Access (15%) — into one Composite Score measuring urban potential across Melbourne’s small areas.

Population growth carries the highest weight because demand drives everything else. Jobs diversity and housing mix balance economic stability with efficient land use, while CBD access reflects connectivity and convenience.

Use the dashboard to search, sort, and filter by metric — compare fast-growing neighbourhoods with job-rich or highly connected areas. Green bars show Composite Score strength at a glance.

High-scoring zones like North Melbourne and Southbank combine strong population growth, diverse jobs, vertical density, and central location — the essential ingredients for Melbourne’s sustainable urban future

Slide 10: Key Insights

Key Takeaways & Data Sources

Key Insights:

By 2043, Melbourne will transform from 354,801 to 584,262 residents — a 64.7% increase or 2.53% annual growth. This is more than expansion; it’s a redesign of how the city lives, works, and builds.

  • Strategic Growth, Not Sprawl New dwellings cluster around infrastructure: North Melbourne (+47.3%), West Melbourne & Kensington (+30–35%), and the CBD–Southbank–Docklands core. Growth follows transit, not distance.

  • A Young, Balanced Workforce The 25–39 age group remains dominant (45% → 42%), the gender ratio stays near 50:50, and seniors rise modestly, sustaining a strong working base.

  • Knowledge Economy Rising By 2040, almost 40% of jobs come from business, finance, health, and public services — signalling a shift to a high-value, idea-driven economy.

  • Vertical Living by Design Apartments now define urban life — 60–100% of housing in fast-growing areas. With height comes responsibility: public space, active streets, and quality design matter.

  • Investment Follows Fundamentals High-scoring zones like North Melbourne and Southbank combine people, jobs, density, and access — the blueprint of a resilient, transit-oriented city.

Melbourne’s future isn’t just predicted — it’s planned. From data to design, from insight to action, the choices made today will shape the city of 2040.

This report draws on the City of Melbourne 2040 outlook and associated datasets (CSV + PDF). Together, they ground the narrative in evidence—so strategy follows the numbers, not the noise.
