Armenia
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.

Most recent snapshot: Taking into account the entire (i.e. aggregate) street network in Armenia as of 2014, the overall level of street-network sprawl is 4.07, which is highly disconnected.
Trends in street network construction: The SNDis of street construction for the respective time periods are 3.7, 4.19, 4.6 and 5.42. In each period, new street development in Armenia steadily grows more disconnected than in the last.
Quantity of street network construction: The street network in Armenia spans a total of 16541 kilometers. It is dominated by roads constructed in 1976-1990. These roads have an SNDi of 4.19, which is highly disconnected.
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 3.7, 3.94, 3.99 and 4.07. Overall, the SNDi of the aggregate street network has risen: the street network in Armenia has become more disconnected. This increase has slowed: between 1975 and 1976-1990, SNDi rose by 0.23 points, but between 1991-2000 and 2001-2014, it rose by just 0.08.
The level of street-network sprawl in new development in Armenia rose steadily. To get a sense of how street development has changed in Armenia, we can consider three of its most populous regions: Erevan, Shirak and Lori. Out of the three regions, Erevan and Lori do not follow the same trend as the country. The level of street-network sprawl in new development in Erevan followed a zig-zag trend with an overall increase. The level of street-network sprawl in new development in Lori followed a zig-zag trend with an overall decrease.
How do development practices in Armenia fare in comparison to others in the world? Most recently in 2001-2014, street construction in Armenia was the 45th-most disconnected out of the 155 countries in the world. Its position in the ranks since 1975 has not changed. Armenia ranked 45th in 1975, 44th in 1976-1990, 60th in 1991-2000 and 45th in 2001-2014.
The largest city in Armenia is Yerevan, with a population of 1132700 people. Taking into account the entire (i.e. aggregate) street network in Yerevan as of 2014, the overall level of street-network sprawl is 3.87, which is highly disconnected. The level of street-network sprawl in new development in Yerevan rose steadily.
As of 2014, the city with the most disconnected street network in Armenia is Yerevan with an SNDi of 3.87, which is highly disconnected. Conversely, the most connected city is Gyumri with an SNDi of 3.14, which is in the 40th to 60th percentile of disconnectedness. See trends for these cities: Gyumri, Yerevan
