Which Is Correct Data Is Or Data Are

The question of “Which Is Correct Data Is Or Data Are” has plagued writers and speakers for ages. It boils down to understanding the origins of the word “data” and how it’s evolved in modern usage. Is it a singular, collective noun or a plural one? Let’s delve into the grammatical nuances to settle this debate once and for all.

Unraveling the Grammatical Knot Data Is or Data Are

The word “data” comes from the Latin word “datum,” which is singular. Traditionally, “data” was considered the plural form of “datum,” much like “agenda” is the plural of “agendum.” Therefore, strict grammarians have historically insisted that “data” should always be treated as a plural noun, requiring a plural verb (e.g., “data are”). This perspective emphasizes the origins of the word and maintains a consistent grammatical structure. Adhering to this strict grammatical rule ensures precision and clarity, especially in academic and formal writing.

However, language evolves, and the usage of “data” has shifted over time. In contemporary English, it’s increasingly common to see “data” treated as a mass noun or an uncountable noun, similar to words like “information” or “furniture.” In this context, “data” refers to a collection of facts or figures as a whole, rather than individual pieces of information. As a result, it’s often used with a singular verb (e.g., “data is”). This usage is particularly prevalent in informal contexts and when referring to data as a general concept.

To illustrate the different usages, consider these examples:

• “The data are inconsistent and require further analysis.” (Plural usage, emphasizing individual data points)
• “The data is readily available online.” (Singular usage, emphasizing the collective body of data)
