Catalão 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 Catalão plotted against Goiás and Brazil. All three follow the same trend in new construction, suggesting a shared regional pattern of development. Most recently, Catalão's incremental SNDi rose from 1.44 to 1.71 between 1991-2005 and 2006-2020. In terms of the aggregate network, Catalão ranked 5th out of 17 cities in Goiás and 15th out of 365 in Brazil as of 2020.

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

In new street additions, Catalão fluctuated in its street-construction patterns, while Husainabad built increasingly disconnected streets over time and Kozhencherry built increasingly connected streets from 1975 through 1976-1990, then shifted to more disconnected patterns. For the full network, Catalão and Husainabad both became progressively more disconnected, while Kozhencherry became more connected from 1975 through 1976-1990, then grew more sprawly from 1976-1990 onwards. Catalão and Husainabad have been growing further apart in their street-network character since 1975.
