Is “Data” Singular or Plural? Usage in Academic and Business

When you write about “data,” you might wonder whether to treat it as singular or plural, especially since expectations change depending on your field. Academic journals often demand one style, while business reports might follow another. If you’re aiming for clarity and professionalism, it’s important to understand the rules—and why they’re shifting. Before you settle on your next sentence, consider what’s really at stake when you pick your phrasing.

Historical Roots and Evolution of "Data"

The term "data" originates from the Latin word "datum," which refers to a singular piece of information. In contrast, "data" serves as the plural form, historically being treated as such in academic contexts. This traditional approach emphasized the distinction between individual data points and the collective set they comprise.

However, language evolves, and over time, the usage of "data" has broadened, especially in informal and business environments where it's often treated as a mass noun, similar to "information." This shift has been particularly pronounced with the advent of big data and advanced analytics, where the practicalities of data management and interpretation may take precedence over strict grammatical conventions.

Despite this trend, many style guides and academic frameworks continue to advocate for the plural treatment of "data." They argue that adhering to its Latin roots maintains clarity and precision, which are essential in scholarly writing and professional discourse.

The debate over singular versus plural treatment of "data" highlights the tension between linguistic evolution and the preservation of traditional grammatical accuracy in various contexts.

Prescriptive vs. Descriptive Grammar in Practice

Grammar often presents complexities that go beyond straightforward rules, particularly with terms like "data."

The prescriptive grammar perspective maintains that "data" should be treated as a plural noun, typically accompanying plural verbs such as "are." This traditional view aligns with its usage in statistical and academic contexts.

On the other hand, descriptive grammar reflects a shift in common usage, where "data" is frequently employed as a singular noun, particularly in non-technical settings.

This distinction highlights the ongoing evolution of language and suggests that the choice between singular and plural forms is context-dependent.

Effective communication in English may require adjustment based on the audience and the specific circumstances of the discourse.

Guidance From Major Style Guides and Institutions

Leading style guides provide distinct recommendations regarding the treatment of "data" in writing.

According to the AMA Manual of Style and APA Style, "data" should be treated as a plural noun, as seen in the phrase "data are," particularly in academic and scientific contexts. This recommendation acknowledges the term's Latin roots and aligns with formal usage.

Conversely, the AP Stylebook adopts a more adaptable stance, allowing "data" to be treated as singular in general writing, but still supports the plural form in scientific or statistical contexts.

Furthermore, both the Chicago Manual of Style and the Royal Statistical Society advocate for the plural usage in formal academic statistics while also acknowledging that the choice may depend on the specific context and target audience.

Singular or Plural: Implications for Academic Writing

Different style guides provide varied recommendations, but academic writing typically emphasizes consistency and accuracy—particularly with the term "data."

In scholarly settings, it's common to use "data are" as the accepted form, with various institutions and respected references, such as the IEEE and the AMA Manual of Style, advocating for the plural usage.

For those engaged in academic writing, adhering to the traditional view of treating "data" as plural enhances the rigor of scholarly dialogue and supports precise statistical writing, where clarity and credibility are essential.

Although language usage has evolved—allowing some contexts to use "data is"—most style guides maintain that writers should follow the plural form to ensure precision across research and formal documentation.

As business communication evolves in response to contemporary trends, "data" is increasingly recognized as a singular mass noun. This shift reflects a growing emphasis on practicality and efficiency in communication.

In particular, style guides, such as The Guardian, now endorse the use of singular verbs with “data,” marking a notable change in usage within business contexts.

This trend highlights the importance of clarity and acceptance in communication, particularly when addressing diverse audiences. While there remains a faction that supports the traditional plural form, a majority of professionals tend to favor the informal conventions associated with singular uses of the term.

Understanding the expectations of your audience, alongside current linguistic trends, is essential for selecting the appropriate form—whether singular or plural. This consideration is important for fostering engagement and ensuring that the intended message is communicated effectively.

Regional and Disciplinary Differences in Usage

Building on the evolving preferences in business communication, it's important to note that the treatment of the word "data" varies significantly across different fields and regions.

In academic contexts, particularly within statistics and scientific disciplines, "data" is typically regarded as a plural noun. As a result, one may encounter the phrase "data are," which is aligned with established style guides in those domains.

Conversely, in business and marketing environments, the singular usage "data is" is more frequently employed, reflecting a preference for clarity and simplification in communication.

Regional variations also influence this usage. In American English, singular treatment of "data" has gained traction in recent years.

Some U.K. publications, including The Guardian, have begun to accept the singular form as well. This distinction illustrates how both disciplinary focus and regional practices contribute to the overall interpretation of "data," establishing it as an interesting case of linguistic evolution.

Recommendations for Consistent and Clear Usage

To ensure your use of "data" is both correct and consistent, it's important to first assess your audience and the context in which you're writing.

In academic writing, the term "data" is typically treated as a plural noun, as in "data are," while in business contexts, singular usage such as "data is" is often preferred.

To maintain consistency, choose either the singular or plural form based on the audience's expectations, and apply that choice consistently throughout your document.

When referencing specific data points, it's advisable to use the plural form. For broader discussions involving general datasets, the singular form may be appropriate.

It's beneficial to consult relevant style guides such as APA, IEEE, or the Chicago Manual of Style for specific recommendations on usage. Adhering to these guidelines will contribute to clarity and professionalism in both academic and business writing.

Conclusion

When you’re writing, knowing whether to treat “data” as singular or plural depends on your context and audience. In academic circles, stick to the plural for precision, following style guides. But in business, using “data” as a singular mass noun is widely accepted and practical. Pay attention to your readers’ expectations and your field’s standards, and always prioritize clear, consistent communication. By doing so, you’ll ensure your message is both professional and easy to understand.
