Data: Countable or uncountable? English for You Hastings' answer is here.

The question I'm going to answer today is from Patrice, who emailed to ask if the word data is countable or uncountable. Here's my answer (which also applies to the word agenda).:

Traditionally, it was countable (because it's a Latin neuter plural), but it is now treated as uncountable. For 'mass noun' below, read 'uncountable noun':
The Oxford English dictionary defines it as follows:In Latin, data is the plural of datum and, historically and in specialized scientific fields , it is also treated as a plural in English, taking a plural verb, as in the data were collected and classified. In modern non-scientific use, however , despite the complaints of traditionalists, it is often not treated as a plural. Instead, it is treated as a mass noun, similar to a word like information, which cannot normally have a plural and which takes a singular verb. Sentences such as data was (as well as data were ) collected over a number of years are now widely accepted in standard English. Technically the singular is datum/agendum, but we feel it sounds increasingly hyper-correct, old-fashioned and pompous to say "the data are".
