The World’s Largest Urban Workforces

Shanghai leads the list with 18.4 million working-age residents, followed by Beijing at 16.5 million. Shenzhen, ranking fifth on the list, is a manufacturing hub and has the highest proportion of working-age adults aged 25–64, accounting for 83.3% of its population.

Meanwhile, India, the world’s most populous country, has two cities on the list with Delhi and Mumbai both being among the cities with the biggest workforces.

New York is the largest U.S. city on the list, ranking sixth with 13.3 million working-age adults. Other American cities with significant workforces include Los Angeles, Chicago, and Dallas.

In terms of growth in working-age populations, the city of Bengaluru in India leads, averaging 2.4% annual growth over the last five years. Canada’s financial hub, Toronto, follows at 2.2%, with Shenzhen ranking third at 2.1% average growth in working-age population from 2019 to 2024.

However, urban labor markets are not growing everywhere. Cities like Seoul, Hong Kong, and San Francisco are seeing declines in their working-age populations, driven by aging, declining birth rates, and migration patterns.
