Sachsen-Anhalt: region in Germany
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 Sachsen-Anhalt as of 2014, the overall level of street-network sprawl is 2.29, which is in the 40th to 60th percentile of disconnectedness.
Trends in street network construction: The SNDis of street construction for the respective time periods are 2.07, 2.76, 3.34 and 3.04. Street construction in Sachsen-Anhalt increased in disconnectivity initially but has since improved. The streets constructed in 1991-2000 were the most disconnected.
Quantity of street network construction: The street network in Sachsen-Anhalt spans a total of 29198 kilometers. It is dominated by roads constructed prior to 1975. These roads have an SNDi of 2.07, which is relatively well-connected.
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 2.07, 2.21, 2.27 and 2.29. Overall, the SNDi of the aggregate street network has risen: the street network in Sachsen-Anhalt has become more disconnected. This increase has slowed: between 1975 and 1976-1990, SNDi rose by 0.14 points, but between 1991-2000 and 2001-2014, it rose by just 0.02.
The level of street-network sprawl in new development in Sachsen-Anhalt peaked in 1991-2000. To get a sense of how street development has changed in Sachsen-Anhalt, we can consider two of its most populous cities: Magdeburg and Halle (Saale). Out of the two cities, Halle (Saale) does not follow the same trend as the region. The level of street-network sprawl in new development in Halle (Saale) followed a zig-zag trend with an overall increase.
