On average, each of the tourists arriving in 2018 spent about 250 US Dollars. Conversely, the inhabitants of Tunisia spend as much as 339 dollars a year when they themselves spend vacations abroad.
Development of the tourism sector in Tunisia from 1995 to 2018
The following chart shows the number of tourist arrivals registered in Tunisia each year. Anyone who spends at least one night in the country but does not live there for more than 12 months is considered a tourist. Insofar as the survey included the purpose of the trip, business trips and other non-tourism travel purposes have already been excluded. The number of people passing through within the same day, and e.g. crew members of ships or flights are also not considered as tourists in most countries. If the same person travels in and out more than once within the same year, each visit counts again.
Data in the chart are given in millions of tourists. The red line represents the average of all 6 countries in Northern Africa.

Revenues in tourism
In 1995, tourism revenues amounted to 1.84 billion USD, or about 10.19 percent of the gross national product. This corresponded to about 4.12 million tourists at that time and roughly 446 USD per person. Within 23 years, the country's dependence on tourism has decreased substantially. In the last year of the survey, the revenue now amounts to 2.32 billion USD, accounting for 5.8 percent of the gross national product. Each visitor now spends an average of 280 USD for his holiday in Tunisia.
