For nearly two decades,the Johns Hopkins University Center for Civil Society Studies research group has conducted comparative research on volunteer work and the nonprofit sector. This year, in conjunction with the International Labour Organization (ILO) and in collaboration with the United Nations Volunteers and an international Technical Experts Group, the Johns Hopkins Center has published a Manual on the Measurement of Volunteer Work. The Manual was developed “to help statistical agencies around the world track the amount, type and value of volunteer work in their countries” in a systematic, regular and comparative fashion. Although national statistical agencies are its primary focus, the influential document also provides food for thought for measuring volunteer work at the organization level. This quarter’s Research to Practice presents highlights from this work.
