We derive an expression which relates fluctuations in particle number, in the thermodynamic limit with fluctuations within a sub-region of an N-particle, two-dimensional, simple fluid. The accuracy of our result is tested against simulation results for a two-dimensional, hard-sphere fluid at a low,
