US national defense spending is the main driver of Guam’s economy, followed closely by tourism and other services.

Total federal spending (defense and non-defense) amounted to $1.988 billion in 2016, or 34.2 of Guam’s GDP. Of that total, federal grants and cover-over payments amounted to $3444.1 million in 2016, or 35.8% of Guam’s total revenues for the fiscal year. In 2016, Guam’s economy grew 0.3%.
