Mongolia in context: Street-network sprawl of new development

The level of street-network sprawl in new development in Mongolia rose steadily. To get a sense of how street development has changed in Mongolia, we can consider two of its most populous regions: Ulaanbaatar and Orhon. None of the most populous cities follow the same trend as the region. The level of street-network sprawl in new development in Ulaanbaatar peaked in 1976-1990. The level of street-network sprawl in new development in Orhon followed a zig-zag trend with an overall decrease.

How do development practices in Mongolia fare in comparison to others in the world? Most recently in 2006-2020, street construction in Mongolia was the 116th-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 Mongolia has become more disconnected. Mongolia ranked 142nd in 1975, 113th in 1976-1990, 123rd in 1991-2005 and 116th in 2006-2020.

The largest city in Mongolia is Ulaanbaatar, with a population of 1231400 people. Taking into account the entire (i.e. aggregate) street network in Ulaanbaatar as of 2020, the overall level of street-network sprawl is 4.51, which is sprawly. The level of street-network sprawl in new development in Ulaanbaatar peaked in 1976-1990.

Mongolia in context: Aggregate street-network sprawl

As of 2020, the city with the most disconnected street network in Mongolia is Ulaanbaatar with an SNDi of 4.51, which is sprawly. Conversely, the most connected city is Erdenet with an SNDi of 2.09, which is well-connected. See these two cities’ trends in the above graph, or dive deeper into each: Erdenet, Ulaanbaatar.

The level of street-network sprawl in the aggregate network in Mongolia rose steadily. To get a sense of how the aggregate street network has changed in Mongolia, we can consider two of its most populous regions: Ulaanbaatar and Orhon. Out of the two regions, Orhon does not follow the same trend as the country. The level of street-network sprawl in the aggregate network in Orhon fell steadily.

To date, Mongolia is the 127th-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 Mongolia has become more disconnected.
