Podgorica's favourable position at the confluence of the Ribnica and Morača rivers and at the meeting-point of the fertile Zeta Plain and Bjelopavlići Valley has encouraged settlement. The city is close to winter skiing centers in the north and to seaside resorts on the Adriatic Sea. Podgorica is home to approximately 30% of the country's population. It is also the nation's administrative center and its economic, cultural, and educational focus.
