  In a family of $S_{d+1}$-fields ($d=2,3,4$), we obtain the true upper and
lower bound of the residues of Dedekind zeta functions except for a density
zero set. For $S_5$-fields, we need to assume the strong Artin conjecture. We
also show that there exists an infinite family of number fields with the upper
and lower bound, resp.
