units Although a public airport, Henry E. Rohlsen Airport has serviced aircraft from the United States Air Force, as well as the United States Army. Economy Tourism is the Islands' biggest industry; with 2.5–3 million annual visitors, the sector is responsible for about 60% of the GDP. Other major sectors are the public sector, some limited agriculture, and small scale manufacturing, most notably rum production. A 2012 economic report from the U.S. Census Bureau indicated a total of 2,414 business establishments generating $6.8 billion in sales, employing 32,465 people and paying $1.1 billion in payroll per year. Between 2007 and 2012, sales declined by $12.6 billion, or 64.9 percent. (In 2007, total sales were $19.5 billion and the number employed was 35,300.) According to a report on the first half of 2016 by the VI Bureau of Economic Research, the unemployment rate was 11.5 percent. In May 2016 the islands' Bureau of Economic Research indicated that there were 37,613 non-agricultural wage and salary jobs in the islands. This report states that the "leisure and hospitality sector" employed an average of 7,333 people. The retail trade sector, which also serves many tourists, averaged another 5,913 jobs. Other categories which also include some tourism jobs include arts and entertainment (792 jobs), accommodation and food (6,541 jobs), accommodation (3,755 jobs), and food services and drink (2,766 jobs). A large percentage of the 37,613 non-farm workers are employed in dealing with tourists. Serving the local population is also part of the role of these sectors. In a May 2016 report, some 11,000 people were categorized as being involved in some aspect of agriculture in the first half of 2016, but this category makes up a small part of the total economy. At that time, there were approximately 607 manufacturing jobs and 1,487 natural resource and construction jobs. The single largest employer was the government. In mid-February 2017, the USVI was facing a financial crisis due to a very high debt level of $2 billion and a structural budget deficit of $110 million. Since January 2017, the U.S. Virgin Islands government has been unable to raise financing from the bond market at favorable interest rates, and as of June 2019 have not issued any new bonds since then. Personal income The median income for a household in the territory was $40,408, and the median income for a family was $52,000 according to the 2020 census.
