The Other Half of the City: Night-Time Economy Is Reshaping Global Urban Life

When the City Wakes at Night

When night falls, the city does not truly sleep. It simply breathes at a different rhythm.

In New York, restaurant lights remain on past midnight, and hurried footsteps still echo through subway stations; in London, taxis weave through the streets of the financial district as crowds spill from closed bars into late-night food stalls. These scenes form the other side of the urban economy—a vast ecosystem that runs from six in the evening to six in the morning.

The numbers are striking: New York's nighttime economy generates $35.1 billion in annual revenue and supports about 300,000 jobs; London contributes £2.6 billion, corresponding to more than one million local jobs. These are not just cold statistics, but the daily reality of countless night-shift nurses, musicians, chefs, security personnel, and ride-hailing drivers.

But for a long time, these twelve hours were treated as an appendage of the daytime—a neglected curve. Today, more and more city administrators are beginning to realize that the night is not leftover fragments, but a frontier yet to be fully developed.

From "Nightlife" to "Night Governance"

The "24-hour city" is not a new term. In the 1980s, American sociologist Murray Melbin proposed that time is a scarce resource that, like land, can be developed as a "new frontier." This concept subsequently emerged organically in multiple cities around the world, initially merely to improve nighttime safety and promote the revitalization of central urban areas.

More than three decades later, the meaning of the 24-hour city has become far richer. It is no longer just about extending business hours or adding nightlife options, but rather treating time itself as a strategic urban resource—by optimizing services from evening to early morning, making the city more resilient in its round-the-clock operation.

To manage this complex territory, more than 60 cities worldwide have appointed "night mayors" or established dedicated departments. These roles are not simply party coordinators; they must address real and mundane urban conflicts: How can workers leaving the night shift get home safely? How can late-night music be balanced with residents' sleep? How can public spaces remain welcoming in the dark?

The City's Rhythm Under Extreme Heat

Climate change is forcing cities to rethink the value of the night.

In Saudi Arabia, extreme heat makes outdoor activities a luxury. As a result, picnics in parks after sunset have become a habit for many families. Similar situations are emerging in American desert cities and the Gulf region: parks, beaches, and public spaces are being redesigned with the addition of lighting, and the night is being liberated as a buffer zone from scorching hot days.

Urban design strategies are therefore beginning to flip. In the past, public spaces were planned mainly around daylight, circulation, and daytime activities; today, the nighttime experience has become part of climate adaptation. Urban public life at night is more intimate and relaxed than during the day, and it better reflects the genuine needs of residents.

Designing Infrastructure for Night Travelers

For the nighttime economy to truly thrive, it cannot rely solely on alcohol and beats. It requires an invisible infrastructure—safe streets, reliable transportation, and affordable services.Orlando offers an interesting case. Local bars and clubs typically close at 3 a.m., and the departure rush from midnight to 3 a.m. often causes congestion and safety hazards. To address this, the city government partnered with Uber and Lyft to temporarily transform bus lanes into geofenced pickup and drop-off zones, equipped with public restrooms, food trucks, music, and seating. This not only improved safety but also made waiting more lively.

London, meanwhile, turns its attention to another often-overlooked group: night workers. The city has about 1.6 million people—one-third of its workforce—working at night or in the early morning. To ensure they can find a decent place to rest even at 4 a.m., London is building "Night Work Centers" that provide sanitary facilities, rest spaces, charging services, and even a sense of community.

The Nighttime Pulse in Data

Consumption data is revealing the vitality of the night. After tracking spending trends across different parts of New York, the Mastercard Economics Institute found that spending at restaurants and bars rose significantly after the pandemic, with nighttime spending in the Financial District—Friday through Sunday—up 135% since 2019.

This phenomenon is thought-provoking. The Financial District was once a typical "office enclave"—bustling during the day and silent at night. But now, it seems to be evolving into a true mixed-use neighborhood. The growth in nighttime spending is not just a rebound in entertainment demand; it also signals that the function of city centers is being redefined.

Toward a Truly 24-Hour City

The rise of digital commerce and the spread of remote work have changed traditional commuting patterns and made daytime foot traffic in high-density commercial areas less certain. In this context, the nighttime economy has become an important fulcrum for urban revitalization.

International collaboration is also deepening. The World Economic Forum and Mastercard have jointly convened a "24-Hour City Network" composed of cities, academics, communities, and the private sector, holding thematic discussions on everything from governance, safety, and mobility to economic development. Orlando's transit overhaul and London's night work centers are both products of this kind of collaboration.

A truly 24-hour city does not require every street to be brightly lit and endlessly active. It means a city is willing to take care of its residents even in the dark hours—those who start work in the early morning, those who adjust their routines because of extreme heat, and those who prefer to wander only at night.

When a city learns to respect the other half of the day, it becomes truly complete.
