Google Search Volume by Language is a project that presents the volume of web searches by the geographical location of the search. As you can see from the lines on the globe below, this type of data visualization can show languages spoken and the amount of computer (and internet access) in different areas.
In the picture below, you can see the differences between North and South Korea. This is a way of highlighting the question of information access and how the lack of access can affect a country.
It is also interesting to just look at the data and see countries that speech the same language. This might be a way to get students to begin thinking about the impact of history and how past events affect us today.
There is a link on the bottom of the page, where you can get the code and build your own data map. This would be useful for students looking at research with available data sets.
