The population has grown from 307,669 inhabitants in 1900 to 578,210 in 2003, and population density has increased from 29 inhabitants per km2, to 55.65. Demographic growth has been less than the Spanish average and the density figures continue to be low. The district capitals, particularly Pamplona and its metropolitan area, have grown to the detriment of areas with a predominance of small rural villages.

By municipality size, 42.3% of the population in Navarre lives in municipalities with over 20,000 inhabitants -Pamplona, Tudela and Barañáin- 39.2% in municipalities with 2,000 to 20,000 inhabitants, and 18.5% in municipalities with less than 2,000 inhabitants. In recent years, as in the rest of Spain, Navarre has been welcoming a considerable immigrant population. It is estimated that over 30,000 people have come from developing countries. Most of these immigrants have settled in the Pamplona district, with the rest spread out throughout the region, although largely in the southernmost part.
