Studies of sustainable ways of life have hitherto made limited use of register data since, e.g., voluntary simplicity is usually identified through characteristics that cannot be found in data registers. Despite this, claims about these trends have been made in many countries, at times gen-eralising the phenomena both in academia and media, based on anecdotal examples. This article draws on a quantifiable definition of holistic simplicity (Etzioni 1998) that includes certain fully measurable aspects, such as living in more affluent suburbs, moving to less affluent places and a significant reduction in individual work income. Other aspects are partially observable in register data, such as housing and car consumption. The advantage of this study is that it combines relevant theories around voluntary simplicity with register data that capture important characteristics of the entire national population (in this case, in Sweden) and thus, to some extent, also captures the mag-nitude of the phenomena. The article aims to statistically explore different demographic groups’ probability of becoming holistic simplifiers in Sweden, regarding their consumption, gender and age. It discusses opportunities and limitations for advancing our knowledge on voluntary simplicity in Sweden, with current findings suggesting more of the same consumption patterns and only initial paths to degrowth. This is discussed in the context of individuals’ agency in a state such as Sweden, which is changing from collectivist social democratic values to more neo-liberal conditions.
