We evaluate asymptotically the variance of the number of squarefree integers up toxin short intervals of lengthand the variance of the number of squarefree integers up toxin arithmetic progressions moduloqwith. On the assumption of respectively the Lindelöf Hypothesis and the Generalized Lindelöf Hypothesis we show that these ranges can be improved to respectivelyand. Furthermore we show that obtaining a bound sharp up to factors ofin the full rangeis equivalent to the Riemann Hypothesis. These results improve on a result of Hall (Mathematika 29(1):7–17, 1982) for short intervals, and earlier results of Warlimont, Vaughan, Blomer, Nunes and Le Boudec in the case of arithmetic progressions.
