The gaming industry opened in 2002, and since then the gaming casinos have grown to become a major part of Macau’s economy. Macau’s other areas of economy are insurance, finance, and real estate. Macau has been transformed into a leading global tourism destination owing to its large investments in resort and entertainment projects. The city enjoys a relatively high GDP; 70% of all employment belongs to service areas such as hospitality and entertainment.
