Is “data” singular or plural?

 

Man with laptop. Word bubble says: Hey, girl. Let's check out some data together

Buckle up, folks. People have strong feelings about whether to treat “data” as a singular or plural noun. And we are going to talk all about it today.

Technically, “datum” is the singular version, and “data” is the plural version.

This means—technically—“data” takes a plural version of a verb.

Examples:

The data are correct.
The data show these numbers.
The data illustrate the findings.

But . . . these days, most people treat “data” as if it were singular. So they use a singular verb with it.

Examples:

The data is correct.
The data shows these numbers.
The data illustrates the findings.

This is where you have to make a decision. Are you going to be a stickler and fight for “data” as a plural, or are you going to buckle under peer pressure and treat it as singular?

You are entitled to your own thoughts about this. But guess what? Language does change. It evolves. For instance, we don’t use “decimate” to mean “to destroy by one tenth” anymore, right? Or what about “nice”? Once upon a time four centuries ago, it meant “foolish and ignorant.” And once upon a time seven centuries ago, “girl” meant a “small child,” whether they were female or male.

So if you want to treat “data” as a singular noun, go for it. It’s true that the times they are a-changing. And if you want to treat “data” as plural, go for it, too. You’re not incorrect, but know you may find people who think you are.
