The great fall during the decade 61-71 is due to the great “agricultural way-out” having as target the foreign emigration to the countries of West Europe.(mostly Germany)
During the decade 71-81 there is a steadiness while at the same time there is a trend of returning home both from those who had a job abroad and from those who had a job in Greece.
It is really important to underline the fact that the greatest part of the population of the Prefecture lives and has a job in the town, where the real number overpasses 80.000 (almost the half of the Prefecture). At the same time the population in statistics is smaller; and this happens because of errors done in the procedure of census.
