| Economy - overview | The economy depends on US military spending, tourism, and the export of fish and handicrafts. Total US grants, wage payments, and procurement outlays amounted to $1 billion in 1998. Over the past 20 years, the tourist industry has grown rapidly, creating a construction boom for new hotels and the expansion of older ones. More than 1 million tourists visit Guam each year. The industry has recently suffered setbacks because of the continuing Japanese slowdown; the Japanese normally make up almost 90% of the tourists. Most food and industrial goods are imported. Guam faces the problem of building up the civilian economic sector to offset the impact of military downsizing. | The economy depends on US military spending, tourism, and the export of fish and handicrafts.
