This graph shows how the top 60 most populated cities in the world compare in overall urban stress by combining air pollution, housing affordability, and climate burden into a single composite ranking, revealing a spectrum from relatively balanced cities like Toronto and Buenos Aires to highly strained megacities such as Hanoi and Delhi.

X-axis: Air pollution (US AQI from IQAir 2025). Score weightage is 50%, since air quality has the most direct effect on life expectancy and healthcare burden.

Y-axis: Housing unaffordability. The ratio is median property price ÷ median annual household disposable income, which is also the number of years of total household income needed to buy a median-priced home outright (assuming you spend nothing else). Weighted 30%. Anything above 20 is the zone where even high earners cannot build property wealth in a single working lifetime.

Bubble size: Climate Stress Index. Heat, humidity, wet-bulb days, dependence on AC for survival. Weighted 20%.

Indian metros are highlighted in terracotta; the numbers inside each bubble correspond to the city's stress rank in the table (1 = least stressed, 60 = most stressed).
