The chart above shows the evolution of street network disconnectedness of the most connected and most disconnected cities in Angola, for both new street additions (left) and the aggregate street network (right).
Angola in context: Street-network sprawl of new development
The level of street-network sprawl in new development in Angola rose steadily. To get a sense of how street development has changed in Angola, we can consider three of its most populous regions: Luanda, Benguela and Huíla. None of the most populous cities follow the same trend as the region. The level of street-network sprawl in new development in Luanda fell steadily. The level of street-network sprawl in new development in Benguela peaked in 1991-2005. The level of street-network sprawl in new development in Huíla followed a zig-zag trend with an overall increase.
How do development practices in Angola fare in comparison to others in the world? Most recently in 2006-2020, street construction in Angola was the 28th-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 Angola has become more disconnected. Angola ranked 76th in 1975, 28th in 1976-1990, 36th in 1991-2005 and 28th in 2006-2020.
The largest city in Angola is Luanda, with a population of 7107800 people. Taking into account the entire (i.e. aggregate) street network in Luanda as of 2020, the overall level of street-network sprawl is 2.44, which is relatively well-connected. The level of street-network sprawl in new development in Luanda fell steadily.
Angola in context: Aggregate street-network sprawl
As of 2020, the city with the most disconnected street network in Angola is Buco-Zau with an SNDi of 6.01, which is very sprawly. Conversely, the most connected city is Xangongo with an SNDi of 1.12, which is very well-connected. See these two cities’ trends in the above graph, or dive deeper into each: Xangongo, Buco-Zau.
The level of street-network sprawl in the aggregate network in Angola rose steadily. To get a sense of how the aggregate street network has changed in Angola, we can consider three of its most populous regions: Luanda, Benguela and Huíla. None of the most populous cities follow the same trend as the region. The level of street-network sprawl in the aggregate network in Luanda fell steadily. The level of street-network sprawl in the aggregate network in Benguela peaked in 1991-2005. The level of street-network sprawl in the aggregate network in Huíla was at its lowest in 1976-1990.
To date, Angola is the 47th-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 Angola has become more disconnected. Angola ranked 76th in 1975, 61st in 1976-1990, 53rd in 1991-2005 and 47th in 2006-2020.
