grassroots organizing

A grassroots movement uses the people in a given district, region, or community as the basis for a political or social movement. Grassroots movements and organizations use collective action from volunteers at the local level to implement change at the local, regional, national, or international levels. Grassroots movements are associated with bottom-up, rather than top-down decision-making, and are sometimes considered more natural or spontaneous than more traditional power structures.
