Since it's a Latin word, Latin rules generally apply.
In Spanish, its dato and datos.
But in modern usage, it is "la data" and "los datos". I pulled examples of this usage from both Spanish and Mexican official (government) reports and private reports.
And while Latin rules apply in Romance languages in most occasions, that is not an absolute. And yes, I took 6 years of Latin and 2 of Greek.
In any case, there is plenty of data to support the RAB gross revenue figures.
