The John Hopkins Listening Post Project released a report describing their findings from a 2007 survey of 872 nonprofit organizations nationwide in four fields (children and family services, elderly housing and services, community and economic development, and the arts). The survey meant to find out "how recent challenges are affecting nonprofit engagement in policy advocacy, and how this varies by field, size of agency, or other factors. Moreover, we know very little about what factors affect the willingness of nonprofit organizations to engage in lobbying and advocacy, or what forms their involvement takes." They found that the majority of nonprofits do engage in such activity, but only devote very little resources to it, either because of funding or staffing issues. The report reiterates the importance of nonprofits' role in policy and advocacy work. Read the report "Nonprofit America: A Force for Democracy".
