Asymmetric federalism or asymmetrical federalism is found in a federation or confederation in which different constituent states possess different powers: one or more of the states has considerably more autonomy than the other substates, although they have the same constitutional status. The division of powers between substates is not symmetric. This is in contrast to symmetric federalism, where no distinction is made between constituent states. As a result, it is frequently proposed as a solution to the dissatisfactions that arise when one or two constituent units feel significantly different needs from the others, as the result of an ethnic, linguistic or cultural difference.
