It's almost 25 years ago that sir Tim Berners Lee invented the World Wide Web; time to evaluate and see how the world is dealing with it.

The Web index is a measure of the Web's growth, utility and impact around the world. It has been designed and produced by the World Wide Web Foundation.

In this visualization each country is represented by an icon divided into four squares. Each square gives a measure to the following subindexes:

• Universal Access: This sub-Index measures whether countries have invested in affordable access to high quality internet infrastructure, as well as investing in the education and skills citizens need to use the Web well.
• Relevant Content: This sub-Index maps both Web use by citizens and the content available in each country, with an emphasis on the extent to which different stakeholders can access information that is relevant to them, in the language that they are most comfortable using and via platforms and channels that are widely available.
• Freedom and Openness: This sub-Index assesses the extent to which citizens enjoy rights to information, opinion, expression, safety and privacy online.
• Impact and Empowerment: This sub-Index aims to assess the difference that the Web is making to people, and the extent to which use of the Web by stakeholders is fostering positive change in four key areas: society, economy, politics and environment.

These subindexes can give us an idea of how healthy the web is in these 81 countries.

It's easy to see that the variation in magnitude of these four components can be quite big within a country. While a country can score good in some of the subindexes it can still score quite bad in the rest.

There are also regional trends and surprisingly also exceptions within one region.
