i was just reading about chinas 1.4 boy to girl birth ratio and it has me wondering is this going on in the united states? it seems to me like finding the right girls has always been a fight. shotgun wedding i hope not.
Where did you read this? It sounds a little high. The sex ratio among the population was 1.12 a few years ago[1]. It's astounding that in that list of nearly 200 countries, there is not a single one with a male/female ration < 1. Or, there's just some simple genetic (rather than social) reason for it, that my biologically challenged mind is unaware of.light_bulb said:i was just reading about chinas 1.4 boy to girl birth ratio...
Are you talking about "replacement level fertility"? 2 births per woman is obvioiusly the correct figure. However, for some reason, girls that die before reaching child-bearing age are typically taken out of the equation so that the often cited figure is 2.1 births per woman. This figure, if maintained over a few generations, would result in a steady population. It also assumes that there will be about the same number of girls and boys born. However, the 2.1 figure is obviously not a precise one and so all assumptions are taken to be "rough".Schrodinger's Dog said:I believe the US the number of children is around 2.2 which explains why it's population is increasing as around 2 is considered the cut off point, for rather obvious reasons.

This site indicates that the figure for the US is 2.03

In spite of the deficiency (2.03 rather than 2.1), population increases in the US for a variety of reasons. For one thing, the 2.03 figure has not been in effect for the length of time necessary for a steady state. Also, we have a significant influx of immigrants. In countries where children are more likely to reach childbearing age, the 2.1 figure may be a little high. I think the US probably can get away with a smaller figure than the world average.
I assume that in communities where there is a supersufficiency of women of childbearing age, there is a tendency toward polygamy. You need one girl and one boy to make one child, but you only need one boy and two girls to make two.Schrodinger's Dog said:Yes but more girls means less children in certain communities as a whole, since you need a girl and a boy to make another girl/boy.

The Iraq war over population control refers to the belief that the United States' invasion of Iraq in 2003 was driven by a desire to control the country's population and resources, rather than the stated reasons of removing weapons of mass destruction and promoting democracy.
There is no direct evidence to support this theory. The official reasons for the invasion of Iraq have been widely debated, and while some argue that population control may have been a secondary motive, there is no concrete proof to support this claim.
Population control is not a stated goal of the Iraq war. However, some argue that the overthrow of Saddam Hussein's regime and the implementation of a new government was a way for the US to gain control over Iraq's population and resources.
If the theory of population control in Iraq is true, it could have significant implications for the country's future. It could lead to continued unrest and instability as the US and other foreign powers try to assert control over the population and resources, potentially causing further harm to the Iraqi people.
The theory of Iraq war over population control is a controversial one, and there is no widely accepted consensus among experts. Some dismiss the theory as a conspiracy theory, while others believe that there may be some truth to it. Further research and analysis is needed to fully understand the factors that led to the invasion of Iraq.
