The study determines price dispersion for non-built-up land in the Warsaw urban agglomeration. The research examined whether prices of residential land decrease as the distance from Warsaw city centre, or the local centre increases, or maybe also as the area of land increases. The study is divided into the following six sections: Introduction and major research purposes; Literature review, Description of primary characteristics of the Warsaw Metropolitan Area; Description of the research project and method; Analysis of research results; and Conclusions. The data come from 72 areas of the following districts: Grodzisk Mazowiecki, Legionowo, Piaseczno, Pruszków, Warsaw West, Żyrardów, Grójec, Mińsk Mazowiecki, Nowy Dwór Mazowiecki, Otwock, Sochaczew, Wołomin, and Wyszków. Statistical surveys confirm and show correlation between prices of undeveloped land and distance from the Warsaw city centre or local centre and the land plot area.
