The Principality of Monaco has a population of just 36 371 and stretches over an area of 2.02 km~2 (less than a square mile), making it the second smallest and most densely populated country in the world. The warm Mediterranean climate attracts tourists both staying and visiting the Principality from neighbouring coastal resorts. The Formula One Grand Prix, held annually, also adds to visitor numbers with consequent increases in waste production.
