The chart above shows the evolution of street network disconnectedness of the most connected and most disconnected cities in Peru, for both new street additions (left) and the aggregate street network (right).
Peru in context: Street-network sprawl of new development
The level of street-network sprawl in new development in Peru followed a zig-zag trend with an overall increase. To get a sense of how street development has changed in Peru, we can consider three of its most populous regions: Lima Province, Arequipa and La Libertad. Disconnectivity in the most populous cities in Peru follow the same country trend.
How do development practices in Peru fare in comparison to others in the world? Most recently in 2006-2020, street construction in Peru was the 24th-most disconnected out of the 179 countries in the world. Its position in the ranks since 1975 has risen; relative to other countries in the world, street construction in Peru has become more disconnected. Peru ranked 59th in 1975, 100th in 1976-1990, 24th in 1991-2005 and 24th in 2006-2020.
The largest city in Peru is Lima, with a population of 9391300 people. Taking into account the entire (i.e. aggregate) street network in Lima as of 2020, the overall level of street-network sprawl is 2.56, which is relatively well-connected. The level of street-network sprawl in new development in Lima followed a zig-zag trend with an overall increase.
Peru in context: Aggregate street-network sprawl
As of 2020, the city with the most disconnected street network in Peru is Peña Negra with an SNDi of 6.1, which is very sprawly. Conversely, the most connected city is Chimbote with an SNDi of 1.39, which is very well-connected. See these two cities’ trends in the above graph, or dive deeper into each: Chimbote, Peña Negra.
The level of street-network sprawl in the aggregate network in Peru followed a zig-zag trend with an overall increase. To get a sense of how the aggregate street network has changed in Peru, we can consider three of its most populous regions: Lima Province, Arequipa and La Libertad. None of the most populous cities follow the same trend as the region. The level of street-network sprawl in the aggregate network in Lima Province rose steadily. The level of street-network sprawl in the aggregate network in Arequipa peaked in 1976-1990. The level of street-network sprawl in the aggregate network in La Libertad rose steadily.
To date, Peru is the 46th-most disconnected out of the 179 countries in the world. Its position in the ranks since 1975 has risen; relative to other countries in the world, the street network in Peru has become more disconnected. Peru ranked 59th in 1975, 72nd in 1976-1990, 57th in 1991-2005 and 46th in 2006-2020.
