Yesterday, we looked at the effects of class on economic growth. Today, we turn to the relationship between class and innovation.

It's a well-established truism that innovation drives economic growth and development. Nations and regions around the world go to great measures to stimulate innovation in their attempts to create the "next Silicon Valley" which will generate new technologies, improve economic growth, and lift their living standards.

To examine the relationship between class and innovation, Charlotta Mellander used data on patents by country available from the World Intellectual Property Organization. Despite some limitations, patents are the best-available measure of innovation.

The relationships between class and innovation are, if anything, even stronger than between class and economic activity.

The first graph shows the close relationship between innovation and the creative class. The larger the percentage of the creative class in a country, the higher its level of innovation.

The working class and innovation - not so much. Countries with a large working class have much lower levels of innovation.
