The file of Sofia Municipality districts long standing alone on the subject and when asked me for GIS regionalization of other big cities, I read and found the information, so after several hours of work, created sufficiently precise shp files on Varna and Plovdiv.
According to the Territorial Planning Act, every very large city * – i.e. with a population of over 200,000, it must be divided into areas. There are 4 such cities in Bulgaria – Sofia, Plovdiv, Varna, and Burgas. In Sofia regions 24, in Plovdiv are 6, in Varna – 5 and Burgas is still not with separate areas and has six Regional Directorates bringing together some of the neighborhoods and villages included in the city and that proved to be no accurate information (area, boundaries, population). Therefore, even though I visualized Burgas, it is only guesswork and assumptions … But the tracing of other cities is relatively high precision, so I allowed myself to add in the files and population density to be calculated based on Population and Calculated area.
I often joke with the neighborhood where I live – Lyulin that if it is a separate city it will be in the top 10 – it is 8th in population according to official statistics – 123,000 (immediately after Pleven and before Dobrich) and most likely unofficially disputes with Burgas or Ruse for 4-5 place.
The second and third largest urban areas are Mladost in Sofia with 109 thousand and in Varna -Primorsky District with 108 thousand inhabitants. All other districts are under 100,000 inhabitants, the smallest being in Sofia is Bankya with 12,200, the West region in Plovdiv with 40,000, in Varna – Asparuhovo with 28,000 and in Burgas eventually Dolno Ezerovo with 5,000.
However, this with population density in urban areas is a bit misleading. Only calculated for the whole urban environment can be considered relevant and fairly correct. It is no coincidence that areas such as Pancharevski, Kremikovski, Vitosha, Asparuhovo and Osvobojdenie have less than 1000 people per 1 km2, with Pancharevskiy being the best example – over 400 km2 and 63 people per 1 km2. These areas include vast forest and/or water areas or arable land as area and would be relevant when comparing land or municipality level. However, in the areas with more than 70-80% of the living space in their territory, the calculation is quite up to date. And as you can see, the central urban areas in the four cities are over 10,000 people per km2. The most densely populated are in Sofia districts Sredets – 24 400, Vazrajdane with 16 700 and Krasno selo – 14 800. Odessos (Varna) is 4th with 14 200 squares, followed by Oborishte with 14 000, Ilinden – 10 900, Zora (in Burgas) with 10 800 and Plovdiv District Central with 10 300 … There is no need to list one by one, see the datasheets from the files themselves:

* Definition of the size of cities based on population in the TDA. They are classified in the following groups:
“Very large cities” – with a population of over 200,000,
“Big cities” – with a population of 100,000 to 200,000,
“Middle cities” – with a population of 30,000 to 100,000,
“Small towns” – with a population of 10 thousand to 30 thousand inhabitants and
“Very small towns” – with a population of fewer than 10 thousand inhabitants.
