No matter what the outcome of next week's US Presidential Election, one thing is certain — whoever wins is likely going to have to travel a lot as part of his or her job.
Research from the National Taxpayers Union Foundation (NTUF), a non-partisan body showing how American taxpayers' money is spent, shows that presidents are travelling more and more.
The research carried out by the NTUF is shown in our chart this week, which shows the number of trips, the number of visits to individual countries and the total number of days abroad at the end of their terms in office.
* Until end Sept 2016The figures show that the three most recent holders of the most powerful political position on the planet have travelled extensively in their role as the chief exec of America. Bill Clinton is the biggest jetsetter, taking 55 trips while in office. Barack Obama had made the second highest number of trips - 50 by the end of September.
The cost of these trips is substantial. The NTUF says the cost of operating the president's plane, Air Force One, which is used for most trips, costs $180,118 per flight hour. The president's September trip to Asia is estimated to have cost more than $5 million in flight costs alone.
A 1999 report from the GAO, which audits US government spending, found that the cost of a 1998 presidential trip to Africa was $42.8 million, including flights, per diems and related expenses.
In January this year, lobbying organisation Judicial Watch estimated that Obama's presidential travel costs have amounted to more than $72 million in his time in office.
