The hospitality industry, by the numbers that are public
Visitor spending, tax revenue, and jobs in Napa and Sonoma, with the years and the methods attached. Numbers you can trust have dates.

Wine country runs on two economies that are easy to confuse. One grows and makes wine. The other hosts the people who come to see it. This guide is about the second one, and it sticks to numbers that were published, dated, and measured by named studies. A number without a year is a rumor with decimal points.
The first thing to understand is what these studies measure. Visitor studies count travelers and their spending: lodging, food, tasting rooms, retail, transportation. They do not measure the wine industry's production economy, the farming, the winemaking, the wholesale business. Tourism and hospitality are one slice of the region, not the whole pie.

Napa County: the 2023 visitor study
Visit Napa Valley's 2023 visitor profile put the county's visitor volume at 3.7 million people and visitor spending at 2.5 billion dollars, generating 107.5 million dollars in tax revenue. It is the most recent comprehensive public count for the county, and the headline figure behind most claims about Napa's visitor economy.
Read it as a snapshot, not a trend. A single year's study tells you the scale of the visitor economy in that year. It does not tell you whether the valley is up or down, and it was not designed to.
Sonoma County: the 2023 Dean Runyan study
For Sonoma County, the public figures come from a Dean Runyan Associates study of calendar year 2023 travel impacts, published by Sonoma County Tourism. It put direct and indirect visitor spending at 2.113 billion dollars, travel-generated earnings at 1.029 billion dollars, employment at 21,970 jobs, and state and local tax revenue at 217 million dollars.

The study's fine print matters. Its 2023 estimates were labeled preliminary, and its definitions are precise: economic impacts are attributed to visitor trips, meaning overnight stays away from home or nonroutine travel of more than 50 miles one way. The county’s visitor economy is measured the way its authors define it, and they define it carefully.
These are the figures from the edition published in May 2024. Dean Runyan’s later edition revises the 2023 spending figure upward to 2.321 billion dollars, so the edition date matters as much as the numbers. Quote the study, and quote when it was published.
How not to misuse these numbers
Do not add the Napa and Sonoma figures together and call the sum wine country. They cover different counties, different years of fieldwork, and different authors with different methods. The numbers sit side by side in this guide so you can compare them, not so you can combine them.
Do not confuse visitor spending with the wine industry's total economic impact either. A bottle sold in a tasting room appears in both economies; a ton of grapes crushed and shipped in bulk appears in only one. When a new study lands, read the date and the method before the headline. That is the entire discipline, and it fits in one sentence.
