Abstract
We show that, in the space of all totally real fields equipped with the
constructible topology, the set of fields that admit a universal quadratic
form, or have the Northcott property, is meager. The main tool is a new theorem
on the number of square classes of totally positive units represented by a
quadratic lattice of a given rank.
