  1. The impact of immigration on the population structure of Greece[1] Viron Kotzamanis [2], Anastasia Kostaki[3] [1]This research is a part of a research project conducted at the Laboratory of Demographic and Social Analyses, Department of Planning and Regional Development, University of Thessaly, financed by the Greek Ministry of National Education and Religious Affairs (PYTHAGORAS: e-demography, digital platform of information, documentation and analysis of demographic information).

  2. After the 2nd world war until roughly the middle of 70’s, the Greek population exhibited a strong emigration profile. A great amount of emigrants moved to highly industrialized countries especially to the USA, Canada, Australia and W. Germany. • Then, at the early 80’s a part of them came back. • Since the early 90’s the country experience a strong immigration wave, mainly from the neighboring Balkans countries (especially Albania) and secondary from the other East European countries.

  4. This work, analyzing the information of the two recent censuses at a micro geographical level, • Studies the implications of the immigration on the spatial distribution of the population. • Investigates the impact of the immigration flow to the population structure of Greece, by comparing the population profile of the actual (real) population (comprised by natives plus immigrants), in each spatial unit (municipality), with the one of solely natives (i.e. the population to be, if immigration was not existed).

  5. As confirmed by the evidence of the two recent censuses, • during the last two decades Greece has altered from an emigration country to an immigration one; • Immigrants increased dramatically, formed more than the 7% of the population in 2001, being roughly non-existed (less than 2%) in 1991.

  6. Map 2: Percentages (%) of the foreigners in the total population (census data 2001) Map 1: Percentages (%) of the foreigners in the total population (census data 1991)

  7. Map 3: Changes in the percentages of the immigrant population between 1991 and 2001 in the 1034 Greek municipalities (censuses data 1991 and 2001)

  8. Map 4: Location Quotient for the immigrants in municipalities (census data, 2001) Map 3 : Location Quotient for the immigrants in municipalities (census data, 1991) Location quotient = the quotient between the percentage of immigrants in the municipality and the total percentage of immigrants in the country (actually it tells us about their spatial concentration)

  18. In order to investigate the implications of immigration in the population structure of Greece, in a lower geographical level, we consider the native population, as well as the actual (real) one (natives plus immigrants) of each spatial unit (municipality), and then, we build the differences between the values of the following characteristics in each spatial unit, for the two populations. • proportion of males • mean age • proportion of population aged [15, 65) • proportion of population aged 65+ Finally, using statistical classification (statistical clustering) techniques, We classify municipalities in homogenous groups (clusters) according to specific statistical criteria based to the size of these differences. In order to reveal the optimal grouping of the municipality units into homogenous groups, we utilize the procedure of Two-step Cluster Analysis, an exploratory statistical technique designed to reveal natural grouping (or clusters) in a data set that would otherwise not be apparent. The analysis is implemented in the SPSS statistical package

  19. CLUSTERING BY COUNTRY GROUP Attribute Importance Cluster Distribution Cluster Profiles

  20. Findings According to the nationality of the immigrant, the municipalities form five distinct profiles: • Profile 1: Highest presentation of Group I and IV (for Group I more than 50% compared with country mean = 14,35%, and for Group IV, 8,77 in comparison to the country mean = 4,37%. Lowest presentation of Group II (less than a half of their mean presentation in the country). N=84 • Profile 2: Highest presentation of Group III (more than 50% compared with country mean = 9,49%),Lowest presentation of Group II (less than the half of their mean presentation in the country), N=55 • Profile 3: High presentation of Group II (more than double the country mean); Somewhat lower presentation of the other groups. N=120 • Profile 4: Highest presentation of Group II ( 88%), Very low presentation of the other groups. N=513 • Profile 5: Highest presentation of Group I; Low presentation of Groups II and III. N=242

  27. RESULTS: • In 30% (295 out of 996) of the municipalities the proportion of males exhibit statistically significant increase. • In 43% (428 out of 996) of the municipalities the mean age of the population becomes statistically significant higher. • In 28% (282 out of 996) of the municipalities the population in active ages exhibit statistically significant increase. • In 30% (299 out of 996) of the municipalities the proportion of population aged 65+ exhibit statistically significant decline.
