It's Time to End the 'Data Is' vs 'Data Are' Debate (vice.com)
dmoberhaus writes: After receiving too many irate emails about using "data" in the singular, a reporter spoke to two lexicographers about how the language changes over time and why it's perfectly acceptable and perhaps even "standard" to use data as a singular noun, rather than a plural noun in an attempt to settle an old debate. Peter Sokolowski, a lexicographer for the Merriam-Webster Dictionary, told the reporter that data's transition between its historical roots and contemporary use is related to a lexical phenomenon called "semantic bleaching," where a word's original meaning is lost or diminished over time. An example of semantic bleaching include the contemporary use of the word "literally," whose Latin root, littera, means "letter." In the case of "data," it has transitioned from "things given" to mean something like "a collection of information in aggregate" when used in everyday speech.
kinda like "deer" is both the singular of "deer", and also the plural of "deer".
I still want to know why in the UK they say "in hospital" instead of "in the hospital". What's up with that? And don't get me started with "math" vs "maths".
I'll stop saying "data are" when the rest of you stop using plural verbs with collective nouns. The team "IS" winning, not the team "are" winning. Sure, they may say it like that across the pond (the UK), but here (the US) collective nouns are singular and take a singular verb (most of the time - there are a few exceptions).
