Eurostat published the results of the survey studying the living conditions across European Union. The numbers are a couple of years outdated, but I don’t think things have changed dramatically during this time.
Cross-country comparisons (see Figure 5) reveal that in 2016 more than half of the population in Croatia (51.4 %) and Cyprus (59.8 %) reported having difficulty or great difficulty in making ends meet, while this share rose to more than three fifths of the population in Bulgaria (61.7 %) and to more than three quarters of the population in Greece (76.8 %); more than half the populations of the former Yugoslav Republic of Macedonia (55.5 %; 2015 data) and Serbia (63.9 %) also faced difficulty or great difficulty in making ends meet.
On the other hand, less than 1 in 10 persons in Sweden (7.6 %), Germany (6.9 %) and Finland (also 6.9 %) reported facing difficulty or great difficulty in making ends meet; this was also the case in Norway (5.4 %).
