The SNDi of new construction in Chiro rose steadily, compared to Oromia which followed a zig-zag trend with an overall increase and Ethiopia which followed a zig-zag trend with an overall increase. Most recently, Chiro's incremental SNDi rose from 5.96 to 10.08 between 1991-2005 and 2006-2020.

What about similarly populated cities?
In new street additions, Chiro built increasingly disconnected streets over time, while Nikli built increasingly disconnected streets from 1975 through 1991-2005, then improved and Yuanzhou fluctuated in its street-construction patterns. For the full network, Chiro and Nikli both became progressively more disconnected, while Yuanzhou fluctuated in connectivity.
