Classification vs. Category — What's the Difference?

Difference Between Classification and Category


Key Differences

Classification is a process used to organize or sort objects, data, or concepts into groups based on common characteristics, while categories are the specific groups that result from this process.
In the field of taxonomy, classification includes creating hierarchical structures such as kingdoms, phyla, and species, whereas a category might specifically refer to one of these ranks.
In data analysis, classification helps in sorting data into predefined categories, whereas categories are used to label these data points for easier analysis and interpretation.
Classification systems can be complex, involving multiple layers and criteria, whereas a category is typically simpler, focusing on a single aspect of similarity among its members.
In everyday language, classification is often used to refer to the method or criteria of grouping, while categories are used to refer to the actual groups that have been formed based on these criteria.

Each of a possibly exhaustive set of classes among which all things might be distributed.


A category or class.


A specifically defined division in a system of classification; a class.


(Biology) The systematic grouping of organisms into categories on the basis of evolutionary or structural relationships between them; taxonomy.

The act of forming into a class or classes; a distribution into groups, as classes, orders, families, etc., according to some common relations or attributes.


Kant's modes of subjective understanding, such as singularity, universality, or particularity, that organize perceptions into knowledge.


The act of forming into a class or classes; a distribution into groups, as classes, orders, families, etc., according to some common relations or affinities.

The act of distributing things into classes or categories of the same type


A property or structural unit of a language, such as a part of speech or a type of phrase.


A group of people or things arranged by class or category


A specific grammatical defining property of a linguistic unit or class, such as number or gender in the noun and tense or voice in the verb.


The basic cognitive process of arranging into classes or categories


(Mathematics) A class of objects, together with a class of morphisms between those objects, and an associative composition rule for those morphisms. Categories are used to study a wide variety of mathematical constructions in a similar way.


Restriction imposed by the government on documents or weapons that are available only to certain authorized people


A group, often named or numbered, to which items are assigned based on similarity or defined criteria.
This steep and dangerous climb belongs to the most difficult category.
I wouldn't put this book in the same category as the author's first novel.


(mathematics) A collection of objects, together with a transitively closed collection of composable arrows between them, such that every object has an identity arrow, and such that arrow composition is associative.
One well-known category has sets as objects and functions as arrows.
Just as a monoid consists of an underlying set with a binary operation "on top of it" which is closed, associative and with an identity, a category consists of an underlying digraph with an arrow composition operation "on top of it" which is transitively closed, associative, and with an identity at each object. In fact, a category's composition operation, when restricted to a single one of its objects, turns that object's set of arrows (which would all be loops) into a monoid.


One of the highest classes to which the objects of knowledge or thought can be reduced, and by which they can be arranged in a system; an ultimate or undecomposable conception; a predicament.
The categories or predicaments - the former a Greek word, the latter its literal translation in the Latin language - were intended by Aristotle and his followers as an enumeration of all things capable of being named; an enumeration by the summa genera i.e., the most extensive classes into which things could be distributed.


Class; also, state, condition, or predicament; as, we are both in the same category.
There is in modern literature a whole class of writers standing within the same category.


A collection of things sharing a common attribute;
There are two classes of detergents


A general concept that marks divisions or coordinations in a conceptual scheme
