The 2015 OECD report 'How's Life?' assesses well-being across 36 countries, emphasizing both subjective and objective aspects and the importance of going beyond GDP for a comprehensive understanding of quality of life. Key findings reveal mixed progress in various dimensions, with increases in income and educational attainment, but persistent challenges in areas such as child well-being and long-term unemployment. The report highlights inequalities among children and the positive impact of volunteering on individual well-being.
