The findings revealed that 16,639 tourists from 122 source markets to Tanzania were covered during the 2016 survey. Most visitors came from the United Kingdom, Kenya and the United States of America. There was a notable increase in the number of visitors from Kenya as its share increased to 11.7 percent from 9.7 percent recorded in 2015. This makes Kenya the second largest source market for Tanzania in 2016. Uganda and Burundi were the new entrants in the list of the top 15 source markets for Tanzania largely associated with proximity as well as increasing business interactions. Looking at Tanzania Mainland and Zanzibar separately, the list of the top 15 source markets remained more or less the same.
