During the last half century the European Union has adopted more than 100 000 pieces of legislation. In this presentation I look into the patterns of legislative adoption over time. I tried to create clear and engaging graphs that provide some insight into the evolution of law-making activity: not an easy task given the byzantine nature of policy making in the EU and the complex nomenclature of types of legal acts possible.

The main plot showing the number of adopted directives, regulations and decisions since 1967 is pasted below. There is much more in the presentation. The time series data is available here, as well as the R script used to generate the plots (using ggplot2). Some of the graphs are also available as interactive visualizations via ManyEyes here, here, and here (requires Java). Enjoy.
