Provisional figures from the 2011 national census showed the population of Greece just shy of 11 million people, while four of the capital?s municipalities are among the five most densely populated areas in the country.
The number of permanent inhabitants in the country came to 10,787,690 in May, according to the Hellenic Statistical Authority (ELSTAT), although the definitive figures will not be issued before the latter half of 2012.
The census has identified 5,484,000 women (or 50.8 percent) and 5,303,690 men (or 49.2 percent).
The five municipalities with the most inhabitants per square meter are Kallithea (21,067.6), Nea Smyrni (20,749.6), Athens (16,830.4), Thessaloniki (16,703.3) and Nea Ionia (15,109.7).
Both Kallithea and Nea Smyrni are municipalities adjacent to Athens, which have grown more populous through the easing of building restrictions.
The most sparsely-populated municipalities are the border areas of Prespes (3.05 inhabitants per square kilometer), Zagori (3.78), Paranesti (3.85), Sfakia (4.11) and Nestorio (4.27).
