Budapest metropolitan area

The Budapest agglomeration is an urban conglomeration with Budapest as its center, which encompasses the Hungarian capital city and the surrounding settlements closely tied to it economically, infrastructurally, in the labor market, and in services. The Budapest agglomeration is a monocentric conglomeration: Budapest alone accounts for almost two-thirds of the agglomeration's population, while the second largest settlement, Érd, has a population amounting to 4% of Budapest’s. Considering population density, there is a roughly consistent decrease from the center toward the periphery.

The official list of the 81 settlements belonging to the Budapest agglomeration is included in the 2005 Act LXIV, which establishes the spatial planning of the Budapest agglomeration. In 2007, these 81 settlements had a total population of 2,457,787, and in 2023 it was already 2,577,384, representing nearly one-quarter of Hungary’s population. Of this, the total population of settlements around the capital was 755,290 in 2007 and 906,380 in 2023.
