The Port of Long Beach supports 2.7 million jobs nationwide and drives consumer spending and innovation, according to a new economic impact analysis — contributing more than $300 billion to the total gross domestic product in the U.S.

The analysis, which was released Monday, comes at a time when it is important to highlight the Port of Long Beach’s role in the local, state and national economics, as tariff polices continue changing at the federal level, port and city officials said.

“The Port of Long Beach plays a vital role in moving goods, fueling economic growth and supporting jobs far beyond our city limits,” Mayor Rex Richardson said at a news conference on Monday at the Port of Long Beach’s headquarters. “We move more than a quarter trillion dollars of economic value per year.”

The new economic impact analysis is based on data from 2019 to 2023. A previous analysis was done in 2019 based on 2017 data, said Mario Cordero, CEO of the Port of Long Beach.

The updated port-commissioned study was conducted by Boston firm EBP US, according to a news release.

It serves as a tool to measure and predict how different activities, policies or events affect the economy. The analysis also deepens an understanding of the port’s role in the economy by showcasing how port-related activities add value to economic activity, demonstrating how much they contribute to gross domestic product, employment and tax revenues, officials said.

Some of the key findings from the economic impact analysis include jobs, gross products and fiscal impacts across four geographic regions: L.A., Orange, Riverside, San Bernardino and Ventura counties, the state and the United States.

As one of the busiest seaports in the United States, the Port of Long Beach supports 2.7 million jobs across the nation, including more than 1.1 million in California. In the five-county region, more than 691,000 jobs are connected to port trade, construction and tourism — or one out of 17 jobs. These jobs range from goods movement, construction and manufacturing, agriculture and extraction, and health and educational services, among others.

The Port of Long Beach, according to the analysis, contributes $309 billion to the total gross domestic product in the U.S., which is the final value of goods and services that pass through the port. Statewide, it’s $141.2 billion, and in the five-county region, it’s $82.6 billion.

Taxes generated by port activity in the U.S. are $84.4 billion, according to the analysis, said Kimberly Ritter-Martinez, manager of economics and funding for the Port of Long Beach.

This is the first post-COVID-19 data that shows how strong the Port of Long Beach is and how it’s grown, leaders said, but they also emphasized the need for long-term, strategic and stable policies over tariffs.

“It’s important people know and understand that we were a contributor, a part of the reason why California is now the fourth largest economy in the world,” Richardson said in a later interview, “and that is in jeopardy; trade policy can jeopardize that.”

Earlier Monday morning, the United States and China agreed to slash their massive recent tariffs, restarting stalled trade between the world’s two biggest economies. U.S. Trade Representative Jamieson Greer said the U.S. agreed to drop the 145% tax President Donald Trump imposed last month to 30%. China agreed to lower its tariff rate on U.S. goods to 10% from 125%.

It could take weeks or even months, however, to untangle the backlog and stabilize the system, city and port officials said. The consequences of tariffs on imports from China already are being seen at the port and also impacting jobs, Cordero said.

The International Longshore and Warehouse Union Local 13 — which represents nearly 15,000 workers on the waterfront — is seeing impacts as well, with part-time workers having zero work opportunities due to the trade war, union President Gary Herrera said.

Long Beach leaders also raised alarms about these consequences last week during a news conference.

“A reduction in trade in our ports doesn’t just affect dock workers, truckers, and local businesses; it threatens American jobs and economic security all across our country,” Richardson said during the news conference. “This new report makes it clear, when trade slows here, the effects ripple across supply chains, industries, and communities nationwide. There’s no denying it, we have now entered a space where there’s heightened attention on tariffs. I think what’s important here is we understand just how impactful the Port of Long Beach is.”
