Anthoor 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 Anthoor plotted against Kerala and India. The SNDi of new construction in Anthoor was at its lowest in 1976-1990, compared to Kerala which was at its lowest in 1976-1990 and India which followed a zig-zag trend with an overall increase. Most recently, Anthoor's incremental SNDi rose from 4.94 to 6.24 between 1991-2005 and 2006-2020. In terms of the aggregate network, Anthoor ranked 31st out of 48 cities in Kerala and 1584th out of 1868 in India as of 2020.

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

In new street additions, Anthoor built increasingly connected streets from 1975 through 1976-1990, then shifted to more disconnected patterns, while Warisaliganj fluctuated in its street-construction patterns and Fukang built increasingly connected streets over time. Looking at the full network, Warisaliganj and Fukang both became progressively more connected, while Anthoor became more connected from 1975 through 1991-2005, then grew more sprawly from 1991-2005 onwards. Notably, Anthoor had a more connected network than Warisaliganj in 1975 but the two have since reversed their relative ranking.
