Zagreb lies at an elevation of approximately 122 m (400 ft) above sea level. In the last official census of 2011, the population of the settlement of Zagreb was 686,568, while the total population of its administrative area was 792,875.

Its favourable geographic position in the southwestern part of the Pannonian Basin, which extends to the Alpine, Dinaric, Adriatic and Pannonic regions, provides an excellent connection for traffic between Central Europe and the Adriatic Sea. The transport connections, concentration of industry, scientific and research institutions and industrial tradition underlie its leading economic position in Croatia. Zagreb is the seat of the central government, administrative bodies and almost all government ministries
