A Numbers Game
The best estimate that can be made about the number of living humans in the post-war Macross world is to ask what the UNG requires as a population to sustain the colonization diaspora conducted in the post-Space War I years. The early colonization programs started with the Megaroad fleets; each Megaroad had 80,000 colonists (not including crew and the escort fleet of Zentradi Battlecruisers and UN Spacy Battleships). The Macross Chronicle (both editions from 2008 and 2014) for some reason published a reduced figure of 25,000 colonists per Megaroad. For purposes of this article the original 80,000 colonist count trivia will be used. The Megaroad fleets began less than 4 years after the start of mass cloning in 2010. In 2014, the UNG begins regularly sending 1-2 Megaroad colony fleets of 80,000+ people annually and three such fleets have already launched by that year.
In these 4 years the UNG needed to grow by 24% from 1 million to 1,240,000 just to support the colonist count of the three Megaroad fleets (no crew, no escort fleet count). Unfortunately, we have no numbers for the fleets and no growth rate for Earth, even though Earth became a major population center with a population explosion in 2011. This prompts the need for super-long-distance colonization and close-range colonization fleets (official trivia lacks any figures for these fleets).
By 2014 the UNG Megaroad colonization program demands 160,000 people per year, every year, just on Megaroad colonists alone. This would be in excess of the growing population needed to sustain Earth and any other colonies (such as Eden, colonized the year before in 2013 by a close-range colony fleet). A natural growth rate starting from 1 million people would yield 10,000 people per year at a conservative growth rate of 1%. So mass cloning is yielding at minimum a 16.0% growth rate. However, not every new citizen can be attached to a colony fleet. If they were, Earth, Eden and all other established colonies would be suffering negative growth rates. So it will have to be assumed the growth rate is 17% for established colonies to remain viable. This assumption produces 170,000 people per year.
In 2030, mass cloning ends, but Megaroad super-long-range colony fleets continue to depart. This means that either the "natural" growth rate must be 17% (untenable) or the population of the UNG must be so large that it can naturally sustain the colonization fleet requirements of 160,000 people per year. For a natural growth rate to both sustain colonization fleet requirements and sustain existing colonies, the population of the UNG must be no less than 10 million people by 2030.
However, additional burdens arise upon on the UNG population in 2030. The first New Macross Class colony fleets begin departure in 2030, which include in excess of 1 million people per fleet departing once per year. Since mass cloning has ended and the Megaroad fleets are still ongoing, the UNG must have a population size that can sustain a "natural" growth rate to accommodate colonization fleet requirements of 1,160,000 people per year. At 1% per year, the UNG must have a population of approx 230 million people by 2030 to meet colonization fleet requirements AND sustain natural growth of existing colonies.
The last major population figure that can be derived takes place in 2045. The Macross 7 animated episode Fleet of the Strongest Women saw the UNG absorb Chlore's Meltrandi fleet. The episode describes Chlore’s fleet outnumbering the Macross 7 fleet 500 to 1. In 2008, the Macross Chronicle Issue 5 published the fleet count of the 37th long-distance colonization fleet, which totaled 194 large ships and 2,689 small craft. At a 500 to 1 ratio, Chlore's Meltran fleet would be 97,000 warships and 1,344,500 combat vehicles. If the Zentradi Bodol Main Fleet was again used as a guide for fleet personnel, the 97,000 warships would hold a population of 151,708,000 Meltrandi.
