The impact of increased affluence on life satisfaction is a matter of some controversy. This paper examines the impact of the recent economic boom in Ireland upon the level and distribution of various domains of well-being. There is evidence of a substantial increase in life satisfaction in the domain of finance and of an improvement in mental wellbeing. There is a reduction in inequality and polarisation for virtually all domains of life satisfaction. A social welfare function which is increasing and concave in individual well-being would show an improvement in social welfare over the period.
