We give a complete multifractal analysis for Stern--Brocot intervals, for continued fractions and for certain Diophantine growth rates. In particular, we give detailed discussions of two multifractal spectra closely related to the Farey map and the Gauss map.25 pages, 4 figuresNumber TheoryDynamical Systems37A45; 11J70; 11J83; 28A80text
