Several, Gallup 2019.
Can the difference in income be outweighed by the difference in subjective personal well-being as the most representative indicator of inequality between people? For Nichols (2019), the latest Gallup studies show that the difference in subjective well-being, or level of life satisfaction, can provide a more accurate and complete picture of overall inequality.
Along these lines, the World Happiness Report 2019 shows that global inequality in happiness has increased over the last decade “driven mainly by rising inequality in happiness within countries” (Helliwell, Layard and Sachs, 2019, p. 18). Similarly, the last year assessed by Gallup (2018) has seen the highest rate of inequality in well-being, a measure that seeks to capture the internal degree of inequality among the inhabitants of each country (Nichols, 2019).
In addition, the Gallup Global Report on Emotions 2019 explores the degree to which people in different countries experience both positive and negative emotions in their lives. Thus, the results of this study provide complementary information to those shown from other indicators associated with inequality in levels of personal well-being.
