Some referendums are advisory rather than mandatory; their results suggest rather than dictate outcomes. The Brexit referendum was intended to gauge public opinion but was treated as binding by the government.
Pro Tip 2/3
Public Involvement
Referendums often involve high levels of public campaign activity and media coverage to inform voters. Before the referendum, both sides used social media to mobilize supporters.
Pro Tip 3/3
Single Issue Focus
Referendums usually focus on a single issue or decision, unlike elections which cover many topics. The 1995 Quebec referendum focused solely on the question of Quebec's independence from Canada.
