Yun in context: Street-network sprawl trends
Yun in context
The chart above shows SNDi trends for new street additions (left panel) and the entire network (right panel), with Yun plotted against Yunnan and China. All three follow the same trend in new construction, suggesting a shared regional pattern of development. Most recently, Yun's incremental SNDi rose from 4.81 to 5.34 between 1991-2005 and 2006-2020. In terms of the aggregate network, Yun ranked 68th out of 78 cities in Yunnan and 1620th out of 1843 in China as of 2020.

Rankings go from most connected to most disconnected — rank 1 is the most connected.
What about similarly populated cities?
In new street additions, Yun fluctuated in its street-construction patterns, while Raver built increasingly disconnected streets over time and Minggang built increasingly connected streets from 1975 through 1976-1990, then shifted to more disconnected patterns. For the full network, Yun and Raver both became progressively more disconnected, while Minggang became more connected from 1975 through 1976-1990, then grew more sprawly from 1976-1990 onwards. Yun and Minggang have been growing further apart in their street-network character since 1975.
