Realistic Demographics - Proportional Pop Growth

NOTE: The 2. 2. 5 update shifted the pop growth values pretty much in line with those in this mod. I have been fairly happy with 2. 2. 5 growth rates, and with extensive testing I have not found an appreciably different result. However, I have updated the mod with some tweaked values (largely lowering influence of certain traits) due to popular demand. This is a simple mod to change pop growth so it is more proportionally realistic. It is NOT intended to prevent diverse civilisations or long-term changes in demographic balance. The game already provides many options for being xenophobic (no migration treaties, species rights, etc) and/or horrifically, fanatically xenophobic (genocide, being generally monstrous, etc). Savegame compatible, but best results with restart. Remember to think in RP terms! - If your main species is slowbreeding, sedentary, and nonadaptive. And you intend to have migration treaties with fastbreeding, nomadic, adaptive. And they have the same planet preference. And you want to use no migration or pop controls. Then expect in the long run (100s of years, but depends on your existing pop numbers etc) that on new colonies they will outbreed the starting species. The ratio will shift slowly, though. - Remember! Pop growth in ANOTHER empire can flow into YOURS, even if it is very sedate in your own. Overflow from other civilisations is more an AI problem than weighting one. - If you want to keep some species EXCLUSIVELY on some planets, then use migration controls. PLEASE NOTE: If you notice anything anomalous or odd or apparently bugged, please report it in the thread in the discussions tab of this page, providing as much exact information as possible. Major rebalance: The latest update has majorly adjusted the weighting to solve the problems of runaway exponential growth of species with growth/migration traits and/or slight numerical superiority. See changelog for details and number. Examples: Species A is a slowbreeding, sedentary species. Species
