Population codes above A - why?

?? As a person I don't have a personal sense of how many people are on Earth. It is dependent on pop density (size of land mass.) Humans currently get along in high density cities...
Most people don't realize how much a trillion is.
 
American trillion (one million million, or 10^12) or
European trillion (one million million million, or 10^18)?

European definitively not. Even 10^12 - with everything else being unchanged that is a density increase of about 150x. I guess, Germany or even the whole of Europe would just be one big city... Interesting. What about farming? Ocean farming could become commonplace...

Trying to avoid the political aspects, but no, people are NOT axiomatically getting along in high density areas.

There seem to be three major factors in urban violence rates: societal social conformity expectations (negative correlation), income (negative correlation), and population density (positive correlation). Where society expects conformity, has high income, and low density, violence is either ritualized or absent; Low conformity, low income, high density, violence is endemic (as with cities in Northern Africa).

Tōkyō's high density is stable because of rigid social expectations of conformity and obedience, and relatively high income. By many measures, it's also dystopian due to small housing, high prices, and strict social expectations.

You misunderstood. They are getting alone as well, or not, as they are in high density areas. That wouldn't change.
 
And where do the Trillion other people live?

In other areas. The same as people not living right on beaches today. Where do you think that they'd live?
Example: The LA area has millions of people. An infinitesimal % of them live on the beach. Much of the beachfront commercial. In much of the S.E. U.S. the "beachfront" is swamp. No one lives there.
 
The population density of New York city is about 26,000 people per square mile (approximately half the density of Cairo, Seoul or Paris). The State of Florida is about 66,000 square miles. Covering the State of Florida with the New York Metropolitan area skyscrapers and suburbs, would house a population of 1.7 billion people (Traveller Pop 9). Florida is only about 2% of the area of the United States, so covering the rest of the US with New York Metropolitan area skyscrapers and suburbs would form an urban megacomplex of 98 billion people. That's just shy of Traveller Pop B living in the US with the whole rest of the planet for farms to try to feed them.

Redeveloping the whole land area of the earth using India as a model, would hold more than 144 billion people (again Traveller Pop B).

Neither of those requires any advanced technology.

Wow! Puts it into perspective.
 
It's a doubtful quality of life. It would be forced calisthenics every morning in squads ordered by Social Security Number, the "Physical Jerks" mentioned in George Orwell's "1984", together with people helping each other put on the underarm deodorant since not having it on is a capital crime...:rofl:

I wish for a "F" world since that will allow me to dig up stills from "THX-1138".

Let me challenge that assumption with some higher TL design assumptions.

Let's start with a Megabuilding one mile square at the base and two miles tall with another half-mile deep basement buried into the bedrock for support - home to 300,000 people - as the basic building unit. Now let's place them in a grid with a one mile gap between each Megabuilding and its neighbor. Covering just Florida with these structures will support a population of about 6 billion people (Trav pop 9). Covering all of North America will support a population of about 900 billion people (Trav pop C). Covering all of the Western Hemisphere will support a population of about 2 trillion people (Trav pop D).

First, let's look at the ecology outside of the Megastructures. Each square mile of megastructure is connected to adjacent megastructures by one square mile of parkland, which is itself adjacent to two square miles of wilderness preserve. One quarter of the land in the Western Hemisphere is urban, one quarter is parkland and one-half is wilderness. In addition, all of Europe, Africa, Asia, Austrailia and Antarctica have been returned to undeveloped wilderness.

Now let's look at life in the Megastructure. First, the subterranean one third of each structure is high density farming ... hydroponics, silviculture, vat grown protein ... that supplies about 80% of the food needs of the megastructure. Each of the remaining 528 levels (two stories tall) is home to 640 people. Each person lives in a house with one-quarter acre of private garden per person, where you can enjoy the fresh produce from your own garden. An additional 160 acres of each level are set aside for community gardens and recreational parklands. An additional 160 acres are set aside for a thriving commercial district ... a super-mall with shopping, offices and light manufacturing. Another 100 acres are civic places like government buildings, utilities, libraries, playhouses, museums, water parks and assorted recreational areas. The last 60 acres are dedicated to heavy industry and transportation.

With an acre of floor area per person, these megastructure dwellers enjoy a life similar to any small town farming community, plus access to all of the amenities of living an elevator ride away from a city of 300,000 people.

Who chooses who lives in deserts then?
 
You need to track the energy flow through the ecosystem. The energy-in comes from solar incidence.
If the energy values for the food is greater than that, you'll need to produce energy ( which costs money and resources ). You'll also need to provide the producers ( plants ) with an environment that they are suited for, which means possibly providing a form of 'life support' for them, which costs money and resources.
There is only a finite amount of resources available on a world, therefore, those resources and available energy gives carrying capacity which limits population growth.

Provided you are not a net importer of foodstuffs. See these types of archologies don't get built as stand alone isloated planets but as part of an Imperium. Even a 20-30 system pocket empire could support one or two.
