About The Joy of English

Grammar: data is or data are?

The word data is traditionally a plural, especially in academia. The expectation is that the data be followed by the plural are, were, show etc instead of is, was, show etc.

The modern view, however, recognises as a collective noun and therefore allows data to be treated like information, i.e singular. This is true in journalism in particular, with 'the data shows', 'the latest data is wrong'.
