Data Tables & Visualizations
Each of the three evaluation pillars is represented by a data table showing key indicators across our 9 candidate cities, accompanied by three visualizations that surface patterns in the data.
Pillar 1 Economic Strength
Evaluates each city's capacity to absorb Olympic-scale capital expenditure without triggering post-event fiscal crisis. Key indicators include GDP impact, total cost, revenue, and cost overrun percentages.
| City | Country | Year | Total Cost ($B) | Revenue ($B) | Cost Overrun (%) | GDP Impact (%) | Tourism Boost (%) |
|---|---|---|---|---|---|---|---|
| Milano-Cortina | Italy | 2026 | 4.5 | 3.8 | 45 | 0.6 | 12 |
| Los Angeles | USA | 2028 | 6.9 | 7.5 | 15 | 0.3 | 8 |
| French Alps | France | 2030 | 5.2 | 4.6 | 35 | 0.5 | 10 |
| Brisbane | Australia | 2032 | 7.1 | 6.2 | 60 | 0.7 | 14 |
| Salt Lake City | USA | 2034 | 3.8 | 4.1 | 20 | 0.4 | 9 |
| Istanbul | Turkey | TBD | 11.5 | 8.2 | 110 | 1.2 | 18 |
| Santiago | Chile | TBD | 9.3 | 6.5 | 95 | 1.5 | 16 |
| Johannesburg | South Africa | TBD | 10.8 | 7.1 | 130 | 1.8 | 20 |
| Trojena | Saudi Arabia | TBD | 14.2 | 9.8 | 70 | 1.0 | 22 |
Interactive Ideas (M3/M4)
For the economic pillar, interactive features could focus on comparing financial performance across cities. Users could toggle between confirmed hosts and candidate cities to see how projected costs and GDP impacts differ. A hover interaction can reveal detailed values such as total cost, revenue, and GDP impact for each city, while a sorting option allows users to rank cities by cost efficiency or economic return. Additionally, linking the GDP impact chart with the cost and overrun charts could help users understand how financial risk and economic benefit relate across different host scenarios.
Pillar 2 Infrastructure Capacity
Measures structural preparedness — transit networks, hotel capacity, airport throughput, and existing venue inventory. Cities with strong existing infrastructure avoid building financially ruinous "white elephants."
| City | Country | Hotel Rooms | Transit Score (0-100) | Airport (Mpax/yr) | Rail (km) | Road Density (km/km²) |
|---|---|---|---|---|---|---|
| Milano-Cortina | Italy | 50000 | 62 | 35 | 900 | 2.0 |
| Los Angeles | USA | 110000 | 28 | 88 | 1600 | 3.5 |
| French Alps | France | 45000 | 15 | 12 | 850 | 1.8 |
| Brisbane | Australia | 40000 | 38 | 23 | 700 | 2.4 |
| Salt Lake City | USA | 30000 | 24 | 26 | 550 | 2.1 |
| Istanbul | Turkey | 140000 | 55 | 64 | 2200 | 3.8 |
| Santiago | Chile | 55000 | 44 | 22 | 800 | 2.6 |
| Johannesburg | South Africa | 60000 | 19 | 21 | 650 | 2.3 |
| Trojena | Saudi Arabia | 25000 | 3 | 3 | 300 | 1.2 |
Interactive Ideas (M3/M4)
For the infrastructure pillar, interactive features could focus on exploring capacity and readiness across cities. Users can filter the radar chart to view different cities and compare their infrastructure profiles, including hotel capacity, transit score, and airport connectivity. The transit score pictogram allows quick visual comparison, with hover interactions highlighting each city’s relative performance. Additionally, linking the hotel capacity chart with the radar view can help users understand how individual infrastructure components contribute to overall readiness.
Pillar 3 Sustainability & Legacy
Assesses long-term environmental impact and alignment with natural urban growth. Core metrics include air quality (PM2.5, NO2), green space coverage (NDVI), and whether the Olympic footprint sits within projected urban densification zones.
| City | Country | PM2.5 (µg/m³) | NO2 (µg/m³) | SO2 (µg/m³) | NDVI (0-1) | Urban Growth (%/yr) |
|---|---|---|---|---|---|---|
| Milano-Cortina | Italy | 14.8 | 28 | 4 | 0.55 | 0.3 |
| Los Angeles | USA | 11.6 | 32 | 3 | 0.35 | 0.6 |
| French Alps | France | 7.6 | 18 | 2 | 0.70 | 0.2 |
| Brisbane | Australia | 6.9 | 15 | 2 | 0.65 | 1.2 |
| Salt Lake City | USA | 9.8 | 20 | 3 | 0.45 | 0.8 |
| Istanbul | Turkey | 24.7 | 40 | 6 | 0.30 | 1.5 |
| Santiago | Chile | 21.3 | 35 | 5 | 0.25 | 1.4 |
| Johannesburg | South Africa | 27.5 | 38 | 7 | 0.20 | 1.8 |
| Trojena | Saudi Arabia | 7.2 | 12 | 2 | 0.15 | 2.5 |
Interactive Ideas (M3/M4)
Interactive features for the sustainability pillar include hover comparisons across PM2.5 levels, compact NDVI visual summaries, and a scatter plot to explore the relationship between urban growth and air quality. These interactions allow users to identify patterns and trade-offs between development and environmental performance.
