Before people are able to experience tourism they usually need disposable income (i.e. money to spend on non-essentials); time off from work or other responsibilities; leisure time tourism infrastructure, such as transport and accommodation; and legal clearance to travel.
Individually, sufficient health is also a condition, and of course the inclination to travel. Furthermore, in some countries there are legal restrictions on travelling, especially abroad. Certain states with strong governmental control over the lives of citizens (notably established Communist states) may restrict foreign travel only to trustworthy citizens. The United States prohibits its citizens from traveling to some countries, for example Cuba.
