Basingstoke 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 Basingstoke plotted against England and United Kingdom. All three follow the same trend in new construction, suggesting a shared regional pattern of development. Most recently, Basingstoke's incremental SNDi fell from 3.69 to 3.62 between 1991-2005 and 2006-2020. In terms of the aggregate network, Basingstoke ranked 35th out of 124 cities in England and 42nd out of 143 in United Kingdom as of 2020.
