A power law is a mathematical relationship between two quantities. If the frequency (with which an event occurs) varies as a power of some attribute of that event (e.g. its size), the frequency is said to follow a power law.
For instance, the number of cities having a certain population size is found to vary as a power of the size of the population, and hence follows a power law.
