Probably not possible to implement and might require a DLL however I feel compelled to explain anyway. This is something I've had on my mind for a while but the current way population grows in Civ4 is not how populations would historically grow. Populations usually don't grow in perfect synch with the amount of food that is available. Often the amount of people would easily outstrip the current technological capacity to produce food in a civilization. And for several reasons. People don't necessarily plan families based on the availability of food. Secondly throughout history contraceptive methods weren't always effective. Also certain cultures believe in having lots of children either for religious reasons, protecting one's posterity, or to have more family labor for things such as farm work. Throughout history the most effective contraceptives were sickness, famine, and war. So instead of population increasing or decreasing from the food bar a new bar that's pink would be above it. This new bar would be called the fertility bar. The bar advances to the next population number using fertility points. Base fertility points are earned at +0.1 per population number so as the number of people increases the rate at which they increase increases due to more people having children at the same time. So not a lot when your population is tiny but it eventually adds up as your population grows. Additional fertility points are earned at +1 per surplus amount of healthiness you have in your cities from lower population turnover as older generations live longer and the infant mortality rate decreases. You will receive -0.3 per amount of surplus unhealthiness in your cities from all the filth. And you will receive -0.1 per amount of surplus unhappiness as more people vent their frustrations into criminal activity. The food bar simply stores food but no longer empties and adds population when filled up. The amount of food the food bar can store will be increased by certain buildings like the granary (will lose the store food after growth because of the food bar being changed). The abattoir will be changed to produce 25% extra food for having pigs, cows, and sheep (maybe horse meat?). When there is more demand for food then the amount of food produced the food bar will decrease like normal but once it hits zero things get a little crazy. From that point on you will receive -5 fertility points for each piece of food that is demanded and not supplied as your people kill and cannibalize each other. If your fertility bar drops past 0 it will function like the old food bar where your population decreases by 1 and your instability increases within the city. Maybe certain religious tenets could affect the fertility rate. Perhaps a contraceptives tech in the modern era that could allow your population to never grow past your current food production or abortion clinics (maybe with a random event for your leader to decide to legalize abortion or not).
