Abstract: In this paper we investigate the distribution of the number of primes which ramify in number fields of degree $ d \leq 5$. In analogy with the classical Erdős-Kac theorem, we prove for $ S_d$-extensions that the number of such primes is normally distributed with mean and variance $ \log \log X$.
