From August 25, 2012 to the present, GNHUSA has been carrying out a nationwide action research project, The Happiness Walk, carried out by GNHUSA board members and supporters. On the first leg, two GNHUSA board members walked 594 miles, from Vermont to Washington DC; the Walk most recently completed a leg from Santa Monica, CA to the Bay Area, with a side trip to Hawaii, and resumed March 1, 2018, walking from Petaluma CA to Seattle, Washington, on the 13th leg of the journey. Along the way, Walkers perform audio and video interviews and collect survey responses, introducing the concept of GNH and amassing data that will assist them in tailoring the GNH domains and indicators to American culture.
