New York City’s economy roared back to life in 2024, with record levels of employment and a tourism industry nearly returned to its prepandemic peak.

But uncertainty clouds the outlook for the new year, as the city braces for potentially dramatic policy changes under President Donald J. Trump, who has promised mass deportations of immigrants, high tariffs and a pullback on federal funding of city and state programs.

And some of New York’s gains, analysts said, belie a widening income gap and an affordability crisis that could worsen under the next administration.

There was an average of 4.15 million private sector jobs in New York City through September, the most ever, and 83,000 more than the prepandemic peak, according to a report by the city’s Economic Development Corporation. The city first recovered all of the jobs lost during the pandemic in 2023.

The share of New Yorkers who either had a job or were seeking one, a snapshot of the city’s economic vitality called “labor force participation,” rose to nearly 63 percent, the highest ever recorded. During the pandemic, the same measure dropped to a low of 52 percent, said Melissa Pumphrey, a senior vice president at the economic development group.

“The fundamentals for our labor force are strong,” she said. “And people, especially young people, want to live here.”
