Since 2005, LSE Cities (London School of Economics) has been collecting comparative data on how global cities perform in terms of key spatial, socioeconomic, and environmental indicators.

This is their latest data matrix:

To be clear, it is not a ranking of cities. It is intended to help us better understand how different cities around the world are performing.

Depending on how you're consuming this post, the text may be difficult to read. So here's what each column represents, moving from left to right:

• Current population in the administrative city (millions)

• Current population in the urban agglomeration (millions)

• Average hourly population growth of urban agglomeration 2015 to 2030 (people per hour)

• Administrative city area (km2)

• Average density of built-up administrative area (people/km2)

• GDP per capita in urban area ($, PPP)

• Percentage of country's GDP produced by the metro region

• Population under 20 (%)

• Murder rate (homicides per 100,000 inhabitants)

• Percentage of daily trips made by public transport

• Percentage of daily trips made by walking & cycling

• Car ownership rate (per 1,000 inhabitants)

• CO2 emissions (tonnes per capita)
