Definition of Data
Data is defined as facts and statistics collected together for reference or analysis. It is the plural of the Latin word datum, meaning “something given.” While traditionally considered plural, its usage has evolved, and it is now often used as a noncount (uncountable) noun, especially in informal contexts.
Classification
Classifying “data” depends on the intended meaning and context. Grammatically, it can function as either a plural noun or a noncount noun.
As a plural noun, it refers to multiple individual pieces of information. As a noncount noun, it refers to information in a general or aggregate sense.
The choice depends on whether you want to emphasize the individual components or the overall collection.
Function
The function of “data” in a sentence is similar to that of any other noun. It can act as a subject, object, or complement. The verb agreement, however, changes depending on whether it is treated as singular or plural. When treated as plural, it takes a plural verb (e.g., “The data are“). When treated as singular noncount, it takes a singular verb (e.g., “The data is“).
Contexts
The context in which “data” is used often dictates whether it should be treated as singular or plural. In formal academic writing and scientific research, treating it as plural is generally preferred.
In more informal contexts, especially in business or everyday language, treating it as singular is becoming increasingly common. Ultimately, consistency within a piece of writing is paramount.
Structural Breakdown
Understanding the structural elements related to “data” involves examining its relationship with verbs, pronouns, and quantifiers.
Verb Agreement
Verb agreement is the most critical aspect. When “data” is treated as plural, it requires a plural verb. For example, “The data were analyzed carefully.” When treated as singular, it requires a singular verb. For example, “The data is sufficient for our needs.”
Pronoun Agreement
Pronoun agreement follows the same principle. If “data” is treated as plural, use plural pronouns like “they,” “them,” and “their.” If treated as singular, use singular pronouns like “it” and “its.” For instance, “The data are reliable; they support our hypothesis.” Or, “The data is available on the server; it can be accessed remotely.”
Quantifiers
Quantifiers are words that indicate quantity. When “data” is treated as plural, use quantifiers like “many,” “few,” “several,” and “a number of.” When treated as singular, use quantifiers like “much,” “a little,” and “an amount of.” For example, “Many data points were collected.” Or, “Much data was lost due to the power outage.”
Types of Data
Data can be categorized in various ways, which might subtly influence its usage. Understanding these categories can provide a more nuanced understanding of how to use “data” correctly.
Quantitative Data
Quantitative data refers to numerical information. Examples include measurements, counts, and statistics.
In the context of quantitative data, “data” is often treated as a noncount noun, especially when referring to an aggregate amount.
Qualitative Data
Qualitative data refers to descriptive information, such as observations, interviews, and text. When dealing with qualitative data, “data” is often treated as plural, particularly when referring to individual pieces of information or observations.
Big Data
Big data refers to extremely large and complex datasets that are difficult to process using traditional methods. In the context of big data, “data” is almost always treated as a noncount noun, referring to the massive amount of information as a whole.

Usage Rules
While the trend leans towards accepting “data” as singular, especially in informal contexts, certain guidelines can help you make the right choice.
Formal vs. Informal Contexts
In formal writing (academic papers, scientific reports), it is generally safer to treat “data” as plural. In informal contexts (blog posts, casual conversations), treating it as singular is often acceptable and becoming increasingly common.
Emphasis on Individual Data Points
If you want to emphasize the individual pieces of information, treat “data” as plural. For instance, “The data were collected from various sources, and they show a consistent trend.”
Emphasis on the Overall Information
If you want to emphasize the overall collection of information, treat “data” as singular. For instance, “The data is sufficient for our analysis, and it provides valuable insights.”
Consistency
Regardless of your choice, maintain consistency throughout your writing. Do not switch between singular and plural usage within the same document unless there is a clear and deliberate reason to do so.
Consider the Audience
Consider your audience. If you are writing for a highly technical or academic audience, treating “data” as plural is generally preferred.
If you are writing for a general audience, treating it as singular may be more acceptable.
Use of “Datum”
The singular form, “datum,” is rarely used in modern English. It is best to avoid using “datum” unless you are writing in a highly specialized or technical context where its use is explicitly required.
Common Mistakes
Several common mistakes arise when using “data.” Being aware of these can help you avoid errors and improve your writing.
Incorrect Verb Agreement
One of the most common mistakes is using the wrong verb form. Avoid using a singular verb with plural “data” and vice versa.
- Incorrect: The data is inconclusive.
- Correct: The data are inconclusive.
- Incorrect: The data were analyzed. The data shows a trend.
- Correct: The data was analyzed. The data shows a trend. (if treating as singular)
Incorrect Pronoun Agreement
Another common mistake is using the wrong pronoun form. Ensure that the pronoun agrees with the intended number of “data.”
- Incorrect: The data are reliable, but it needs further analysis.
- Correct: The data are reliable, but they need further analysis.
- Incorrect: The data is sufficient; they provide enough information.
- Correct: The data is sufficient; it provides enough information.
Inconsistent Usage
Switching between singular and plural usage within the same document can be confusing and grammatically incorrect.
- Incorrect: The data is collected daily, and they are stored securely.
- Correct: The data is collected daily, and it is stored securely. (consistent singular)
- Correct: The data are collected daily, and they are stored securely. (consistent plural)
Misuse of Quantifiers
Using the wrong quantifier with “data” can also lead to errors.
- Incorrect: Many data was collected.
- Correct: Much data was collected.
- Incorrect: Much data points were analyzed.
- Correct: Many data points were analyzed.

Advanced Topics
For advanced learners, exploring the historical context and regional variations in the usage of “data” can provide a deeper understanding.
Historical Context
The traditional view of “data” as strictly plural stems from its Latin origin. Over time, as English evolved, the influence of Latin declined, and the usage of “data” as a noncount noun has become more accepted.
Regional Variations
While the trend towards singular usage is prevalent in many English-speaking regions, some areas, particularly in academic and scientific communities, still strongly adhere to the traditional plural usage. Being aware of these regional preferences can help you tailor your language to your audience.
Corpus Linguistics
Corpus linguistics, which involves analyzing large collections of text and speech data, provides valuable insights into how “data” is actually used in contemporary English. Corpus studies have shown a significant increase in the use of “data” as a noncount noun over the past few decades.
