How livable are India's biggest metro cities? How do they fare against each other when it comes to key parameters such as commute speeds, affordable rents, and air quality?

To examine these questions, Mint examined a vast array of public datasets to figure out how different cities fared on each parameter. Based on 10 such key parameters, we then came up with an equally-weighted index to score each of these cities. The Mint Livability Index rankings showed how different cities ranked if you assign equal weightage to each of the parameters considered in the analysis.

But what if you want to assign a higher score on one particular parameter (say clean air) and less on another (say diversity)? This interactive tracker allows you to do exactly that. Just adjust the weights according to what you think is important, and figure out which city might suit you best.

The Mint Livability Index is based on 10 sub-indices. The Commute Speed sub-index reflects the median workweek speeds across major arterial roads. The Public Transport sub-index reflects rail density, metro density, and bus fleet sizes across cities. The Migrant Flow sub-index reflects the proportion of new migrants (between 2001-11) across cities. The Diversity sub-index is the inverse of a segregation index that measures caste-based residential segregation across city wards. The Affordable Housing sub-index reflects the median rental values across city wards. The Dineout sub-index reflects cost, variety, and ratings of top-rated restaurants across cities. The Social Infra sub-index reflects the number of schools and health centres per capita. The Greenery sub-index reflects the green cover per capita. The Clean Air sub-index reflects the inverse of the average pollutant (SO2, CO2, PM10 and PM 2.5) values for these cities in 2018. The Municipal Finances sub-index reflects the municipal spending per capita. Each of these sub-indices is normalized, with the indices taking values from 0 to 100. Higher scores indicate better performance.
