Life expectancy at birth: ∞ - Our civilisation has been able to create bodies and minds which do not degrade. People essentially reach their physical maturity, and then cease to age further. Most people last for several hundred years before "tuning out" - that is, immersing themselves into virtual reality and leaving the real world behind. Some of the tuned out occasionally "surface" for up to a few years at a time, before sinking back into VR space again. Others never stir from VR space. Our "tuned out" citizens are sent to Maralus, the outermost planet of our solar system. Maralus has been hollowed out and filled with Computronium & mass habitation units to allow the storage of trillions of these people. Several civilisations, including the Polity, the Human Federation, the Zefera-Hariyna Alliance and of course the Yanasran Collectives, share the facilities on Maralus
Mean years of schooling: Truthfully, schooling never ends for Yanasrans. Our people take great pride in learning new things and keeping up to date with the latest knowledge
Expected years of schooling: As above - every day is a school day for Yanasrans, until they tune out
Gross national income per capita: Essentially ∞ - we are a post-scarcity society with practically no limit to what we could produce apart from the speed at which we harvest energy from the Hyperspace Field

*There are massive gaps between the rich and poor in these statistics, with the poorest 5% only having a life expectancy of about 63, and the richest 5% have a life expectancy up to 296. The average income in the top 5% is $200,000 (Rising all the way to $569,000 in the top 1% and $3,900,000 in the top 0.1%), whilst the average income in the bottom 5% is, roll the drums...$6,000. I wish I was joking, but no.

Life expectancy at birth: This is actually a huge unknown, and it can range from 77-130 years, as genetic modification has allowed Caleonians’ minds to degrade much slower than the average human, but it’s still developing and can be unstable. If you want a definitive non modified average, then it’s simply 80 years.
