Significance in bold (p < 0.05)
EHIS—European Health Interview Survey (2006/2009); ESS—European Social Survey (2008, 2010, 2012); EU-SILC—EU Statistics on Income and Living Conditions (2008, 2012) for 28 European countries (Finland, Sweden, Norway, Denmark, the UK, Ireland, the Netherlands, Belgium, Germany, Austria, Switzerland, France, Spain, Portugal, Italy, Greece, Cyprus, Slovenia, Croatia Czech Republic, Slovakia, Hungary, Poland, Bulgaria, Romania, Latvia, Lithuania, Estonia)
a Countries without a pair are excluded from the rank comparison
bA value of − 1 indicates complete reversal between the two ranks being compared, 0 that the ranks are independent of each other, and 1 that they completely agree
