The Simplicity Institute has put out a survey for people who are incorporating voluntary simplicity (or downshifting) into their lifestyle:
If you live a 'simple' lifestyle in one way or another, we need your help! The Simplicity Institute is an organization dedicated to research and policy analysis around the topic of simple living, downshifting, and similar lifestyles. This research is profoundly important as it touches the core of global problems such as climate change, over-consumption, work-life balance and a host of other social and ecological issues.
The Simplicity Institute's current research project is focused on people who have chosen a 'simpler' lifestyle, including changes such as reduced or restrained income, reduced consumption or reduced working hours.
Results from the survey have now been published.
