Shire in context
The chart above shows SNDi trends for new street additions (left panel) and the entire network (right panel), with Shire plotted against Tigray and Ethiopia. The SNDi of new construction in Shire rose steadily, compared to Tigray which followed a zig-zag trend with an overall increase and Ethiopia which followed a zig-zag trend with an overall increase. Most recently, Shire's incremental SNDi rose from 1.46 to 3.05 between 1991-2005 and 2006-2020.

What about similarly populated cities?
In new street additions, Shire and Thaton both built increasingly disconnected streets over time, while Yumurtalık built increasingly connected streets from 1975 through 1976-1990, then shifted to more disconnected patterns. For the full network, Shire and Thaton both became progressively more disconnected, while Yumurtalık became more connected from 1975 through 1976-1990, then grew more sprawly from 1976-1990 onwards. Shire and Yumurtalık have been converging in their street-network character since 1975.
