Asteroid families, traditionally defined as clusters of objects in orbital parameter space, often have distinctive colors. We improve the separation of family members from background interlopers by using color measurements for 23,264 objects available in the Sloan Digital Sky Survey Moving Object Catalog. We find that about 50% of asteroids belong to 36 families that are clustered in multi-dimensional space spanned by colors and orbital parameters. This fraction increases from about 35% to 60% as the the limiting asteroid size drops below 25 km, as predicted by earlier work. We examine the asteroid size distributions for the identified families and find that they can typically be modelled by a power-law, although there is a non-negligible fraction of families (25 %) that require a ``broken" power-law. We also find that the size distribution within a family depends on the distance from the family core such that larger objects are more prevalent closer to the core.
