Most of these should be fairly straightforward, even if it may appear lengthy; realistically they shouldn't be too much work to maintain.
Influence is a stat that will only appear for non-powers and represents the relative levels of influence any powers might have in your country (Minor -> Moderate -> Major -> Dependency). More influence means more power over a country's politics, economy, and culture - however that might be used. Economic and trade deals, political agreements, financial or military assistance, migration, and simple cultural contact are all ways influence can grow. The majority of countries in this game are already under a power's influence and most others will have foreign influence build up steadily over time. It is, of course, possible to combat influence.
Politics works like this. Your government type is listed, alongside your head of state (if applicable). If your country has a parliament or legislature, then the ~2-5 largest and/or most influential political groups will be listed, with (in order) their actual size in the legislature (Majority Govt, Minority Govt, Coalition Partner, Large Minority, Small Minority), their level of satisfaction with the current government's policies (Rebellious, Angered, Displeased, Content, Pleased, Delighted). After the parentheses is listed each party's most pressing issue or desire - think of it as the "theme" their campaign might run. The idea is to give you a brief, abstracted overview of the internal situation and political landscape of your country. These political parties can certainly align themselves with - or against - foreign powers.
If your country is a single-party state, an autocracy, or otherwise does not have a legislature, then this will be replaced by a generic "issues" line that lists the 2-3 most pressing issues facing your country.
Next Elections are the date the next elections will be held at or by.
Unrest is a measure of the general level of popular discontent in the country (None, Low, Moderate, High) which can take the form of protests, civil disobedience, riots, or full-on rebellion. Bear in mind that this discontent might not necessarily be against the government.
Living Standards are an abstract measure of how well-off your people are. Higher incomes, greater material wealth, better healthcare, better infrastructure, more pleasant living situations, better safety, greater access to culture and entertainment, and many more things all play into this. Higher living standards are obviously indicative of more developed economies.
Inequality goes hand-in-hand with Living Standards and is an abstract measure of how unequal your wealth is distributed - that can be inequality between classes, regions, or ethnic groups. High inequality can breed discontent.
Corruption is, well, corruption, and higher corruption is a major hindrance to your government.
Your Income is how much money actually is usable by your government - this is influenced by a lot of factors, including corruption, how high your taxes are, how your economy is structured, etc. From here, there are three major fields. For these, there will be a rating (Nonexistent, Poor, Mediocre, Good, Excellent) that give an idea as to the effectiveness and quality of each, which is generally dependent on how much you spend per capita. The numbers listed are simply how much you paid last turn, and are not rigid; you can increase or decrease them as you wish, though doing so will have consequences.
-Education and Research covers funding for schools, colleges, universities, laboratories, research grants, cultural programmes, and whatnot. Higher funding into education is a good way to not only increase literacy but to make any research you conduct significantly more effective.
-Health and Welfare covers funding for things such as healthcare, social security, pensions, and other foundations of your country's welfare system. Increasing funding into this can help sustain a high standard of living and decrease inequality, but having an extensive welfare system is not cheap and may have other consequences.
-Law and Security covers funding for general authority-keeping, the legal system, and police forces, and greater funding makes all of these things more effective. It also covers rather shadier things that may or may not include intelligence agencies and secret police.
Separate but in the same list is Military Upkeep which is how much you need to pay to keep your armed forces active. Not paying your soldiers is an excellent way to make a lot of people with guns unhappy - or worse.
Dependencies - which will list only major colonies or dependencies, so small islands and such won't appear here - are applicable for the half dozen or so countries that do still have them. For each is listed, in order, the total net income from the colony (negative income represents colonies that provide a net loss), the population of the colony, the means the colony is governed (whether directly, through local protectorates, through self-government, or however), and the biggest "issue" or political concern of the colony.
Military stats aren't entirely finalised so I'll hold off on talking about those until later. That being said, however, these are only the public military stats; things such as one's arsenal of WMDs or any special forces will be private.
Yes, space will play a role in the game. We'll get to that when the time is right.
