Usage Discussion of DATA Data leads a life of its own quite independent of
datum, of which it was originally the plural. It occurs in two constructions: as a plural noun (like
earnings), taking a plural verb and plural modifiers (as
these, many, a few) but not cardinal numbers, and serving as a referent for plural pronouns (as
they, them); and as an abstract mass noun (like
information), taking a singular verb and singular modifiers (as
this, much, little), and being referred to by a singular pronoun (
it). Both constructions are standard. The plural construction is more common in print, evidently because the house style of several publishers mandates it.
