Gillingham in context: Street-network sprawl trends

The chart above shows SNDi trends for new street additions (left panel) and the entire network (right panel), with Gillingham plotted against England and United Kingdom. All three follow the same trend in new construction, suggesting a shared regional pattern of development. Most recently, Gillingham's incremental SNDi fell from 6.23 to 5.87 between 1991-2005 and 2006-2020. In terms of the aggregate network, Gillingham ranked 115th out of 124 cities in England and 131st out of 143 in United Kingdom as of 2020.

Rankings go from most connected to most disconnected — rank 1 is the most connected.

In new street additions, Gillingham built increasingly disconnected streets from 1975 through 1991-2005, then improved, while Mianwali built increasingly connected streets from 1975 through 1976-1990, then shifted to more disconnected patterns and Koriyama built increasingly disconnected streets from 1975 through 1976-1990, then improved. For the full network, Gillingham became progressively more disconnected, while Mianwali became more connected from 1975 through 1991-2005, then grew more sprawly from 1991-2005 onwards and Koriyama grew more disconnected from 1975 through 1991-2005, then improved. Gillingham and Mianwali have been growing further apart in their street-network character since 1975.
