Here you can find information about Empire and Senate Screen:
(1) This panel is a general description of your faction. If you forget what unique qualities or abilities your people have, just look here. On this list you will also find the features that you have acquired by assimilating minor factions.
(2) Empire Approval. This is the average value of approval of all systems under your control. If a system has very low approval, an icon will appear here to measure the time until the uprising. The bar below shows how many systems you can colonize before you get penalized for over-colonization.
(3) Victory conditions and the evaluation of your efforts. Here you will find various statistics e.g. how many technologies you have researched or how many planets you control, as well as your position in a given field among other civilizations. The more filled-in squares, the closer you are to a given type of victory.
(1) This window shows your government type, its influence on the empire or other aspects. Once you discover the correct technology, you can change the government type to another with the Change Government button. Below, you will see the time left until the next election and options you can use to affect them. At the bottom there is a chart of support for all of the individual ideologies.
(2) The pie chart shows the support for the representatives of a given party and their total number in the senate.
(3) Active laws. One of the laws of the leading party is always active. You can, however, introduce new laws, from the parties which are a part of the Leading Political Parties. You will also see what the total Influence cost per turn is. Independent laws do not use Influence, where some party specific laws can often have an extremely large cost.
(4) Parties, which have won the election and gained the most support become members of the Leading Political Parties. However, there is only one main party and government leader. This is shown on the Senate Screen icon. Underneath it there is a small symbol of the party which is leading the government (number 4 with the arrow in the upper left corner; under the Senate icon there is also a small red icon of the Militarists). Under each party portrait you will see their level bar (they gain levels quicker, if they are often elected; unlocks more advanced laws) and leader skills (if the hero has any).
(5) Population Census. Here you will see the composition of the population in your empire (white dots indicate how many unlocked Collection levels of a given population there are). After clicking, you will go through a more detailed description of all the races in your empire.
