St. Tammany Parish just posted the highest year-over-year wage growth of any large county in the United States, and the reason has nothing to do with a booming local economy across the board. It comes down to one company, one bonus, and a $3.2 billion corporate buyout that happened to land in the natural resources and mining sector during the first quarter of 2026.
According to federal data cited by NOLA.com, St. Tammany Parish's average weekly wages jumped more than 23%, from $1,204 to over $1,478, marking the highest compensation increase among the 376 largest U.S. counties tracked by the U.S. Bureau of Labor Statistics. That leap wasn't spread across the parish's economy — it was concentrated in extractive establishments, where average annualized wages soared from less than $200,000 to more than $1.7 million, a 772% surge. The employer behind the bonus was withheld under confidentiality rules, per the same federal data.
Louisiana Economic Development economist Jake Polansky described the spike as an anomaly caused by a generous employer bonus, even as he noted that St. Tammany and Richland parishes are both seeing strong labor-market growth despite their very different circumstances. St. Tammany Parish, a Northshore suburb of New Orleans, has increasingly established itself as its own economic region rather than a pure bedroom community.
A $3.2 Billion Buyout Behind the Numbers
The company most closely tied to the bonus timing is LLOG Exploration Co., a Covington-based deepwater operator and the parish's 10th-largest employer, which employed about 125 people. Harbour Energy PLC officially completed its $3.2 billion acquisition of LLOG on February 11, 2026, financing the deal with $2.7 billion in cash and $500 million in voting ordinary shares issued to LLOG Holdings LLC, according to Harbour Energy. Harbour Energy did not respond to a request for comment from NOLA.com regarding the bonus.
Alyssa Leibold, an economist quoted in the same reporting, said large increases like this commonly occur in the first quarter when bonus structures are implemented, adding that she had never seen a 700% increase before. Russell Richardson, also cited in that reporting, said increased investment in St. Tammany has been tied to overall state economic growth, and separately reported that three Gulf leases had been signed in the last year as federal offshore leasing activity reopened. Federal energy policy changes under the second Trump administration reportedly made LLOG a more attractive takeover target, per the same account.
Beyond the bonus-driven spike, St. Tammany added about 1,200 jobs between March 31, 2025, and March 31, 2026, placing it in the top 20% of larger counties nationally for job growth. Textron was cited as one employer bolstered by increased military spending in the parish during that period.
Richland Parish's Different Kind of Boom
While St. Tammany's number reflects a one-time event, Richland Parish's wage growth stems from a genuine industrial transformation. Richland Parish ranked third nationally for annual wage growth among all counties, with wages rising 54% to $1,478 a week from $872 a week — matching St. Tammany's new weekly average almost dollar for dollar, but for very different reasons.
The driver there is Meta's Hyperion Data Center, expected to span more than 5 square miles and cost more than $50 billion to complete. Meta expanded its planned investment from $10 billion to over $50 billion on July 13, 2026, scaling the facility to 5 gigawatts of IT capacity across 3,200 acres and nearly 10 million square feet, according to Louisiana Economic Development. Meta has also announced plans to double the data center's size and intended workforce.
Construction jobs in the parish, which historically relied on agriculture, jumped from fewer than 200 to more than 2,000, while construction wages climbed from less than $47,300 to more than $133,000 annualized. Meta- and Entergy-related employment is predicted to peak at about 9,400 jobs in December, per Leaders for a Better Louisiana. Ampirical, an engineering firm, has benefited from the electrical buildout associated with the data center push.
The tax revenue tied to the construction boom has already reached classrooms: the Richland Parish School District awarded teachers annual bonuses of up to $50,000 in 2026, according to Louisiana Radio Network. Meta has separately committed $1 billion toward upgrading Richland Parish's roads, water networks and wastewater systems, along with a $5 million grant to Louisiana Delta Community College for workforce training, as reported by News Talk 96.5 KPEL.
Power Demands and Land Prices Follow the Boom
Meeting Meta's power needs has reshaped Entergy's own investment plans. The utility increased its four-year capital expenditure forecast by $14 billion to $57 billion in April 2026, seeking regulatory approval for seven new natural gas-fired generation plants totaling about 4.5 gigawatts, according to Utility Dive. Entergy Louisiana and Meta also executed an electric service agreement structured under White House ratepayer protection principles, requiring large customers to cover their costs and projecting savings exceeding $2 billion.
The land rush surrounding the project has been just as dramatic. Meta bought farmland near the Hyperion site, affecting land values, according to the same KPEL reporting.
A Statewide Contraction Beneath the Local Gains
Both parishes' gains stand out against a broader statewide slide. Louisiana's total covered employment decreased 0.5%, or more than 9,000 jobs, over the same period the two parishes posted their gains. Elsewhere in the state, East Carroll Parish wages rose 11.3%, from $40,000 to nearly $44,600 annualized, while Tensas Parish wages increased 18%, from about $41,300 to more than $48,700 annualized. For comparison, Olmsted County, Minnesota, saw weekly wages increase less than 14% over the same span, well below both Louisiana parishes.
The figures come from the Quarterly Census of Employment and Wages, a joint federal-state tally of jobs covered by unemployment insurance programs. The QCEW excludes self-employed workers, independent contractors, armed-forces members, some agricultural laborers and railroad workers, meaning the reported numbers capture only a portion of each parish's total workforce.
