Direct answer: As of the latest available data, New York City has about 4.95 million active registered voters, with turnout in recent major races ranging from roughly 30% to 40% for citywide contests, depending on the election type and year. For the current 2025 mayoral cycle, turnout has been notably high in absolute numbers, with closings suggesting nearing two million voters having participated as results rolled in, though percentages vary by borough and race specifics. If you need a precise, up-to-the-minute figure for a specific date or election (e.g., exact registered voters by borough or the latest turnout percentage for the 2025 mayoral election), I can look up the latest official counts and provide a sourced figure.
