Similar to the EU, the Federation does not receive much coverage in the series. However, the second season revolves around the liberation of Federation citizens, as well as their union with the United States of Japan to form a much larger union later on (a topic to be presented in a later article).Because of its inclusion of the India Militarized Zone, the Liaodong Militarized Zone, and Mongolia, the Federation in-series should have roughly 2.5 Billion citizens, making it the largest territory-by-population in Code Geass. What we know is that the people of the Federation are in a state of poverty, with anger later placed on the governing body (The High Eunuchs) for hoarding much of the resources. Their execution becomes the catalyst which liberates the Federation.
