In order to have a better picture of the Greek business sector, following there is going to be a presentation of Greek business demographic data. Data for the six other European countries previously used will be presented as well. These data come from the OECD, but they concern the year 2007. Despite the six year period since then, these statistics can still offer a good insight in the Greek business sector.
The data presented concern the following aspects:
1)    Enterprises by size class
2)    Value Added by size class
3)    Employment by size class
The OECD uses 5 size classes, all measured according to the number of employees:
a)    1-9 (micro enterprises)
b)    10-19 (small enterprises)
c)    20-49 (small enterprises)
d)    50-249 (medium enterprises)
e)    250+ (large enterprises)
The first 4 categories are called Small Medium Enterprises (SMEs).
Table 6 presents the total number of businesses by size class for the seven European countries. Size is measured from the number of employees they occupy. In the last column we see the total amount of businesses counted in every economy. The largest number of businesses is met in Spain (2.7 million), followed by France (2.5 million), Germany (1.8 million), the UK (1.6 million), Portugal (867 thousands), Greece (829 thousands) and finally Sweden (560 thousands). In order to examine size classes in more detail, it is useful to look at percentages, as presented in Table 7 and Figure 6. Looking at the business size percentages, it is evident that most businesses in the seven European countries examined, are micro enterprises, meaning that they have less than 10 employees. The percentage of micro enterprises ranges from 83% in Germany, to 96.7% in Greece. Small enterprises in Greece (those with 10-49 employees) are around 3% (24.386 enterprises), medium are 0.4% (2.905 enterprises) and large only 0.1% (470 enterprises) University teachers

According to the OECD, value added corresponds to the difference between production and any intermediate consumption, where total intermediate consumption is valued at purchasers’ prices. Table 8 presents value added by size class for the seven European economies. The highest total value added is recorded in Sweden (1.6 trillion €), followed by Germany (1.1 trillion €), France (840 billion €), the UK (786 billion €), Spain (575 billion €), Portugal (72 billion €) and finally Greece (72 billion €). In order to examine the contribution of each size class in more detail, it is useful to look at percentages, as presented in Table 9 and Figure 7. Micro enterprises in Greece offer 37.3% of total value added, while SMEs offer 75%. This percentage is the largest contribution of SMEs in the economy for the 7 counties. Large enterprises, even though they are only 0.1% of total enterprises, they offer 24.9% of the private sector’s total value added. However this percentage is by far the lowest one from the 7 countries examined. The largest contribution of large enterprises is observed in the UK (49%). followed by Germany (46.3%) and Sweden (43.5%).
