# Superset vs. Subset: What's the Difference?

Edited by Huma Saeed || By Sumera Saeed || Updated on November 13, 2023

A superset is a set that includes all the elements of another set, while a subset is a set whose elements are all contained within another set.

## Key Differences

A superset is a larger set that contains all elements of a smaller set within it. Conversely, a subset is that smaller set whose all elements are included in the superset.

In mathematical terms, if set A is a subset of set B, then set B is a superset of set A, meaning all elements of A are also in B. However, B may contain additional elements not in A.

The concept of subset implies a set being fully contained within another without any additional elements. In contrast, a superset encompasses the subset and possibly more elements.

Every set is a subset of itself and also a superset of itself, demonstrating the relative nature of these terms. This principle shows the inclusivity of the set concept in mathematics.

The terms are used not only in mathematics but also in broader contexts, like data science, where subset and superset describe the relationship between data groups.

### Example

If A = {1, 2}, then B = {1, 2, 3} is a superset of A

If B = {1, 2, 3}, then A = {1, 2} is a subset of B
