For the purposes of the Moody's Analytics estimated and forecast data products, we have established geography codes for metropolitan areas in Bulgaria. A formal definition for metropolitan areas is not promulgated by the National Statistical Institute (NSI), but the ESPON 1.4.3 analysis proposed BG41 (the NUTS-code identifier for the NUTS 2 area of Yugozapaden a.k.a. Yugoiztochen) as a proxy for the Functional Urban Area (FUA) of Sofia.
References:
Table 1. Definition of the Sofia metro area. We define it as conterminous with Yugoiztochen, one of Bulgaria's six NUTS 2 regions, which in turn consists of five of the nation's 28 NUTS 3 districts. Note that the districts of Sofia Capital and Sofia are distinct.
