y’all pronounce it data or data?

My memory, which might be faulty, tells me that years ago, when the word was only used by a few quantitative nerdy types, it was routinely pronounced dah-ta. But as computers became more readily available , and "data processing" became a household term, the pronunciation day-ta took over.

I am pretty sure I used to say dah-ta, but now I say day-ta.

Although, the word is Latin for "given things", and was used to describe the inputs for an algorithm (we might say "givens", using "given" as a noun) . The Latin would be pronounced dah-ta.

A related question: do you say "the data is...." or " the data are...." The word is a Latin plural.
