Mumbai in context: Street-network sprawl trends
Mumbai in context
The chart above shows SNDi trends for new street additions (left panel) and the entire network (right panel), with Mumbai plotted against Maharashtra and India. The SNDi of new construction in Mumbai rose steadily, compared to Maharashtra which followed a zig-zag trend with an overall increase and India which followed a zig-zag trend with an overall increase. Most recently, Mumbai's incremental SNDi rose from 4.49 to 5.71 between 1991-2005 and 2006-2020. In terms of the aggregate network, Mumbai ranked 117th out of 157 cities in Maharashtra and 886th out of 1868 in India as of 2020.

What about similarly populated cities?
- Mexico City, México
- São Paulo, Brazil
- Cairo, Egypt
- Beijing, China
- Karachi, Pakistan
- Bangkok, Thailand
Mumbai, Mexico City, and Beijing all built increasingly disconnected streets over time in new street construction. The same pattern holds for the full street network. Mumbai and Mexico City have been converging in their street-network character since 1975.
