A simple twist on the traditional budgeting process has us paying attention to payoffs for transparency. Participatory budgeting (PB) is a political process that lets members of a community vote on how certain budget funds should be allocated. By including the public in decision-making, PB has the potential to be an agent of accountability, helping to demystify city budgets, to turn voters into active contributors and informed monitors of government progress, and to help support efforts for proactive budget disclosure. As it stands today, PB helps communities explore many of these opportunities, and it serves as an important gateway to engagement with local government for a wide variety of residents, especially traditionally-underrepresented groups. It’s a transformative process -- one that may cost governments almost nothing, since it just reallocates existing funds -- and it's a process we’re eager to see explored in more detail as more and more communities hold a magnifying glass to budgetary data.
