Happiness in pre-pandemic Europe: correlates of individual happiness prior to Covid

Abstract Objective: To identify levels and key correlates of happiness across Europe in 2018, prior to the Covid-19 pandemic. Methods: We used data from the European Social Survey to determine levels of happiness in individuals (n = 49,419) from 29 European countries and identify associations between happiness and age, gender, satisfaction with income, employment status, community trust, satisfaction with health, satisfaction with democracy, religious belief and country of residence. Results: In 2018, self-rated happiness varied significantly across the 29 European countries, with individuals in Denmark reporting the highest levels of happiness (8.38 out of 10) and individuals in Bulgaria reporting the lowest (5.55). Ireland ranked 11th (7.7). Happiness had significant, independent associations with younger age, satisfaction with health, satisfaction with household income, community trust, satisfaction with democracy and religious belief. These factors accounted for 25.4% of the variance in happiness between individuals, and, once they were taken into account, country of residence was no longer significantly associated with happiness. Conclusions: Self-rated happiness varied significantly across pre-pandemic. At individual level, happiness was more closely associated with certain variables than with country of residence. It is likely that the Covid-19 pandemic had significant impacts on some or all of these variables. This highlights the importance of further analysis of correlates of happiness in Europe over future years, when detailed happiness data from during and after the pandemic become available.


Introduction
The Covid-19 pandemic increased symptoms of mental ill-health around the world, with multiple studies reporting rises in anxiety, depressive and eating pathology symptoms (Schafer et al., 2022).Less attention has been devoted to the effects of the pandemic on happiness or measures of positive well-being, as opposed to symptoms of mental illness.The World Happiness Report 2021 reports that while there were significant increases in average levels of sadness and worry during the pandemic, overall life evaluations and happiness rankings appeared to remain stable (Helliwell et al., 2021).More work is needed, however, to determine the precise correlates of happiness before, during and after the pandemic, in order to understand trends better.
The fact that the World Happiness Report 2021 documents relatively stable rankings of happiness despite Covid-19 is both surprising and interesting.Trends matter not only when they change, but also when they remain stable despite apparent reasons for change.To elucidate this further, we examine levels and correlates of happiness prior to the pandemic, to both understand the position in 2018 in greater detail and provide a basis for future comparative analysis, when more recent data become available.
A decade before Covid-19, we used data from the European Social Survey (ESS) to study social and psychological correlates of happiness across seventeen European countries (Doherty and Kelly, 2010).We found that self-rated happiness varied significantly, with individuals in Denmark reporting the highest levels of happiness and those in Bulgaria reporting the lowest.On multi-variable analysis, happiness was positively correlated with younger age, satisfaction with household income, being employed, high community trust and religious belief.
Correlates of happiness, however, change over time.We found that satisfaction with health had the strongest association with happiness in Ireland in 2003Ireland in , 2005Ireland in and 2007, but that satisfaction with income increased in significance over time (Doherty and Kelly, 2013).By 2009, satisfaction with income had the strongest association with happiness in Ireland, relative to other variables studied.This was a time of rapid economic change in Ireland, which likely accounts for the close relationship between income and happiness at this point.Mean happiness in Ireland fell to 6.8 in 2012, consistent with Ireland's economic difficulties at that time, but increased to 7.2 in 2014, likely owing to economic recovery (Kelly, 2017).
Against this background, this paper aims to identify levels and key correlates of happiness Europe in 2018, just prior to the Covid-19 pandemic, in order to (a) better understand levels and correlates of happiness in Europe at that time, and (b) provide a comparative basis for analysis of levels and correlates of happiness in Europe over subsequent years, when detailed happiness data from during and after the pandemic become available.

Methods
This paper is based on data from the ESS which is an academically driven cross-national survey that has been conducted across Europe since its establishment in 2001.Every two years, face-toface interviews are conducted with newly selected, cross-sectional samples of individuals aged 15 years or over who are residents in participating European countries (random probability sampling).The ESS measures the attitudes, beliefs and behaviour patterns of diverse populations in more than thirty nations.
Full To measure happiness, each ESS respondent was asked 'Taking all things together, how happy would you say you are?' and rated happiness on a scale from 0 ('extremely unhappy') to 10 ('extremely happy').To measure financial situation, each respondent was asked 'Which of the descriptions : : : comes closest to how you feel about your household's income nowadays?' and rated their financial situation on a scale from 1 ('living comfortably on present income') to 4 ('finding it very difficult on present income').To measure employment status, each respondent was asked 'Have you ever been in paid employment or a paid apprenticeship for more than twenty hours or more per week for at least 3 months?'(yes/no).
Community trust was measured as the sum of answers to three questions: (1) 'Generally speaking, would you say that most people can be trusted, or that you can't be too careful in dealing with people?' where 0 means 'you can't be too careful' and 10 means 'most people can be trusted'; (2) 'Do you think that most people would try to take advantage of you if they got the chance, or would they try to be fair?' where 0 means 'most people would try to take advantage of me' and 10 means 'most people would try to be fair'; and (3) 'Would you say that most of the time people try to be helpful or that they are mostly looking out for themselves?' where 0 means 'people mostly look out for themselves' and 10 means 'people mostly try to be helpful'.For ease of comparison with other scores (many of which were rated out of 10), the score for community trust was divided by 3 so as to be rated out of 10.
To measure satisfaction with health, each respondent was asked 'How is your health in general?' and rated their health on a scale from 1 ('very good') to 5 ('very bad').In order to measure satisfaction with democracy, we used responses to the ESS question 'On the whole, how satisfied are you with the way democracy works in your country?' where 0 means 'extremely dissatisfied' and 10 means 'extremely satisfied'.In order to estimate level of religious belief, we used responses to the ESS question 'Regardless of whether you belong to a particular religion, how religious would you say you are?' where 0 means 'not at all religious' and 10 means 'very religious'.
Data were analysed using IBM SPSS Statistics (Version 28).Bi-variable correlations were calculated using Spearman's or Pearson's test (r), as appropriate.Multi-variable analysis was performed using linear regression analysis with happiness score as the outcome variable.Variables that were significantly associated with happiness on bi-variable testing were included as independent variables.We tested the model for multicollinearity, which is when two or more variables are so closely related to each other that the model cannot reliably distinguish the independent effects of each.To test for this, we calculated a 'tolerance value' for each independent variable; tolerance values below 0.10 would indicate significant problems with multicollinearity (Katz, 1999).
This study was performed in accordance with the Declaration of Helsinki (World Medical Association 2008).Ethical approval was not required by the local research ethics committee because this paper uses only publicly available, anonymised data.Data protection legislation was adhered to at all times.
Mean score for satisfaction with income was 1.96 (where 1 means 'living comfortably on present income' and 4 means 'finding it very difficult on present income'); the greatest satisfaction with income was in Denmark (1.31) and the lowest in Bulgaria (3.03) (Table 1).The percentage of respondents employed was 84.7%; the highest was in Latvia (95.9%) and the lowest in Portugal (63.7%).Mean score for community trust was 5.23 (where a higher score means greater trust, with a minimum possible score of 0 and maximum of 10); the highest was in Denmark (6.87) and the lowest in Serbia (3.56).
Mean score for satisfaction with health was 2.21 (where 1 means 'very good' and 5 means 'very bad'); the highest was in Latvia (2.73) and the lowest in Switzerland (1.81).Mean score for satisfaction with democracy was 5.26 (where 0 means 'extremely dissatisfied' and 10 means 'extremely satisfied'); the highest was in Switzerland (7.54) and the lowest in Bulgaria (2.92).Mean score for religious belief was 4.54 (where 0 means 'not at all religious' and 10 means 'very religious'); the highest was in Cyprus (6.90) and the lowest in Czechia (2.40).
On multi-variable linear regression analysis, happiness had significant, independent associations with younger age, satisfaction with health, satisfaction with household income, community trust, satisfaction with democracy and religious belief (Table 2).Adjusted r 2 for the model was 25.4%; that is, these factors explained 25.4% of the variance in happiness levels between individuals.All tolerance values were greater than 0.10, indicating no significant problems with multicollinearity.

Discussion
We found that, in 2018, self-rated happiness significantly between European countries, with individuals in Denmark reporting the highest levels of happiness and individuals in Bulgaria reporting the lowest.Happiness had significant, independent associations with younger age, satisfaction with health, satisfaction with income, community trust, satisfaction with democracy and religious belief.
Why do we need to understand trends?There is an inconclusive, but growing, literature examining the relationship between population happiness and mental illness, mental disorder and self-harm (Daly et al., 2011).The Covid-19 pandemic has been linked with increased rates of certain mental illnesses in certain populations, but mental illness affects a minority of populations at any given time (O'Connor et al., 2020).However, while it is a Happiness was rated on a scale from 0 to 10, in response to the question: 'How happy would you say you are?'; 0 means 'extremely unhappy' and 10 means 'extremely happy'.
b Satisfaction with income was rated on a scale of 1 to 4 in response to: 'Which of the descriptions : : : comes closest to how you feel about your household's income nowadays?'where 1 means 'living comfortably on present income' and 4 means 'finding it very difficult on present income'.c Community trust was measured as the sum of answers to three questions: (1) 'Generally speaking, would you say that most people can be trusted, or that you can't be too careful in dealing with people?' where 0 means 'you can't be too careful' and 10 means 'most people can be trusted'; (2) 'Do you think that most people would try to take advantage of you if they got the chance, or would they try to be fair?' where 0 means 'most people would try to take advantage of me' and 10 means 'most people would try to be fair'; and (3) 'Would you say that most of the time people try to be helpful or that they are mostly looking out for themselves?' where 0 means 'people mostly look out for themselves' and 10 means 'people mostly try to be helpful'.For ease of comparison with other scores (many of which were rated out of 10), the score for community trust was divided by 3 so as to be rated out of 10. d Satisfaction with health was rated on a scale of 1 to 5 in response to the question: 'How is your health in general', where 1 means 'very good' and 5 means 'very bad'.e Satisfaction with democracy was rated on a scale of 1 to 10, in response to the question: 'On the whole, how satisfied are you with the way democracy works in your country?',where 0 means 'extremely dissatisfied' and 10 means 'extremely satisfied'.f Religious belief was rated on a scale of 1 to 10 is response to the question: 'Regardless of whether you belong to a particular religion, how religious would you say you are?', where 0 means 'not at all religious' and 10 means 'very religious'.
natural for researchers to explore increases in mental illness secondary to Covid-19, because it will affect quality-adjusted life years and disability-adjusted life years, it is likely that overall shifts in population wellbeing or happiness as a result of the pandemic will have a large aggregate effect across populations, given the numbers affected, and might affect risk of mental illness or self-harm.
Many of the findings in this study are consistent with our previous work linking happiness with younger age, satisfaction with income, being employed, high community trust and religious belief (Doherty and Kelly 2010).In the context of the Covid-19 pandemic, the World Happiness Report 2021 found that trust was a key factor linking happiness and Covid-19 control (Helliwell et al., 2021), which is consistent with our finding linking happiness with community trust prior to the pandemic.
Perhaps the most interesting finding in our study is that, after age, community trust, religious belief, and satisfaction with health, income and democracy were taken into account, country of residence was no longer significantly associated with happiness.Further work is needed to determine the precise manner in which different variables interact with country of residence to create the impression that it is country itself, rather than these other variables, that is linked with individual happiness.
Our study has various strengths and limitations.Strengths include the large sample size (n = 49,419); the number of European countries included (n = 29); and the use of data from a methodologically rigorous, well-validated social sciences survey (the ESS).We included a wide range of variables that are associated with happiness.ESS data are available on an open-access basis for other researchers to perform similar or related analyses.
Limitations of this study include the fact that it was a post-hoc analysis of the ESS dataset and therefore, like previous analyses, omits certain variables of possible relevance (e.g.genetic inheritance, childhood circumstances, etc.) (Kelly 2021).Our multi-variable model accounted for 25.4% of the variance in happiness between individuals, suggesting that most of the variance in happiness is attributable to factors other than those in our model.

Conclusions
Happiness varied significantly between countries across pre-pandemic Europe, with Ireland rated 11 th happiest of 29 countries in the ESS.At individual level, happiness was more closely associated with age, community trust, religious belief, and satisfaction with health, income and democracy, than with country of residence.
It is likely that the Covid-19 pandemic had significant impacts on some or all of these factors.As a result, there is a clear need for further analysis of levels and correlates of happiness across Europe in future years, when more detailed happiness data from during and after the pandemic become available.
