Baolun in context: Street-network sprawl trends
Baolun in context
The chart above shows SNDi trends for new street additions (left panel) and the entire network (right panel), with Baolun plotted against Sichuan and China. All three follow the same trend in new construction, suggesting a shared regional pattern of development. Most recently, Baolun's incremental SNDi rose from 4.37 to 4.4 between 1991-2005 and 2006-2020. In terms of the aggregate network, Baolun ranked 88th out of 98 cities in Sichuan and 1713th out of 1843 in China as of 2020.

What about similarly populated cities?
In new street additions, Baolun fluctuated in its street-construction patterns, while Shilong built increasingly disconnected streets over time and Quíbor built increasingly disconnected streets from 1975 through 1991-2005, then improved. Looking at the full network, Shilong and Quíbor both became progressively more disconnected, while Baolun grew more disconnected from 1975 through 1976-1990, then improved.
