# Filters

A **filter** is a tool to explore data through specific **dimensions**.

“*Dimensions*” is usually opposed to “*Facts*”. They are categories for data. For example “Country”, “Business Unit”, “Brand”, and “Year” are **dimensions.**

Viewers, using the App you created, will therefore be guided into their data analysis by interacting with the **filters** and getting answers to questions to get their job done, such as:

> “What are the sales figures for \[This Country] during \[This Year]?”

In order to help you design an App that will be easy to use by your end-users, we have defined different scopes & types of **filters.**

Filters are essential as they’re global and reusable throughout the entire App. Their location in Stories, Home, and Dashboard Builder is thought to explicitly highlight their importance: they are the **main point of view** that you want your end-users to discover.

Filters are a way for App Builders to think about the global message they want to communicate. They are also making it possible to address different **user** **populations** within the same App with strong **permissions rules** (cf. [Permissions](https://github.com/ToucanToco/doc-v3/blob/main/visualizations-and-layouts/creating-layouts/filters/broken-reference/README.md)).

Toucan wants you to build once and then deploy anywhere and to anyone.
