Pará: region in Brazil
What exactly constitutes the spatial extent of the city? For these aggregations, we used the Global Human Settlement Layer Urban Center Database (GHS-UCDB) to define the boundaries of the city. These cities -- or urban centers -- cover areas that are densely populated and built-up, and so may extend beyond the spatial borders of these cities that we may be familiar with. The GHS area is shaded in blue.

Trends in street network construction: The SNDis of street construction for the respective time periods are 3.05, nan, 3.96 and 3.84. Data was not available in 1976-1990.
Quantity of street network construction: The street network in Pará spans a total of 35373 kilometers. It is dominated by roads constructed prior to 1975. These roads have an SNDi of 3.05, which is in the 40th to 60th percentile of disconnectedness.
Effect on the aggregate network: New construction in each period adds to the total stock of streets, but does not change streets that have already been built. Therefore, it has a limited effect on the street network as a whole. The SNDis of the aggregate street network in the respective time periods are 3.05, 3.05, 3.26 and 3.36. Overall, the SNDi of the aggregate street network has risen: the street network in Pará has become more disconnected.
