Lobbyists may be among a legislator's constituencies, meaning a voter or bloc of voters within their electoral district; they may engage in lobbying as a business. Professional lobbyists are people whose business is trying to influence legislation, regulation, or other government decisions, actions, or policies on behalf of a group or individual who hires them. Individuals and nonprofit organizations can also lobby as an act of volunteering or as a small part of their normal job. Governments often define and regulate organized group lobbying that has become influential.
