A Marginal Revolution commenter linked to a study at the blog Multiplier Effect by Gennaro Zezza providing hard numbers on the scale of Greek population decline and emigration. (Germany seems to be a major destination.)
The Hellenic Statistical Authority (ElStat) has recently released the new quarterly data on employment and the labor force, which includes a measure of the population aged 15 or more (Table 1). While the series published in the previous release exhibited a stable upward trend (reported in green in the chart), the new estimates show that population peaked at 9.437 million at the end of 2008, and then started declining, reaching 9.296 million in the first quarter of this year, i.e. it went back to its 2004 level. (The reasons for the change in the series are due to ElStat incorporating the latest census data: details are available in the ElStat web site).
As ElStat does not publish an up-to-date measure of net migration, we assume this could be measured by the distance between the pre-crisis population trend and the actual values. We therefore computed a simple linear trend on the 2001-2008 data, which shows that population would have now been at 9.686 million, had the previous trend continued. The difference between this value and the population reported for the first quarter of 2014 is thus approximately 390,000 people (4 percent).
ElStat makes available the detail by age groups (Table 2), reported in our second chart, which shows that younger Greeks are declining steadily in number – a trend which is common to many developed countries who chose to reduce the average number of kids per family – while the number of older people is steadily increasing – again a trend common to many countries, linked to longer life expectancy. Summing up the 15-29 groups to the 45+ groups, we find that the decline in the younger population accelerated after 2007, compensating the increase in the number of Greeks aged 45 and over, so that the inverted U-shape of the population in our first chart can largely be attributed to the decline in Greek residents aged 30-44, who are now 2.442 million against a peak of 2.544 million at the end of 2008.
