Human mobility is a defining feature of our time. As people increasingly move—across borders, within and across regions and countries, and between communities—their movement raises fundamental, unanswered questions about democratic participation and political inclusion. As migration continues to steadily grow globally, ensuring political inclusion for mobile populations is not merely a technical or operational issue—but a fundamental question of democratic legitimacy. Advancing more inclusive electoral systems requires taking a step back to critically reflect on electoral participation and rethink the fundamental questions of why, where, how, and for whom voting occurs. As patterns of human mobility continue to evolve, closing the gap between human mobility and democratic participation becomes increasingly urgent to meaningfully upholding the principles of universal suffrage, political equality, and truly representative governance.
