Does anyone know what the global average of children that couples/parents have in their life time, who then also go on to reproduce ?

Does anyone know what the global average of children that couples/parents have in their life time, who then also go on to reproduce ?
i don't recall where i saw the figures, but was a google search on population.
China has the lowest ratio with 1.5 per couple and Africa the worst with about 2.7 per couple. most of the industrial countries were around 2. my pure guess would be a little over 2 for overall, which is a good figure to maintain and not increase to rapidly.
remember death ages are now up there as well. what we see as over all populations reflect this as well. a couple on earth in 1930, with this 2 ratio
could be approaching 32 of who is now on earth, never going above that 2 per couple ratio.
Here in Ireland & the UK its 2.5
was 2.4, hence the tv show!Originally Posted by Robbie
I don't know were you are getting your statistics from Robbie but....
Uk, 1.66 (in 2006) https://www.cia.gov/cia/publications...k/geos/uk.html
Ireland, 1.86 (2006) https://www.cia.gov/cia/publications.../print/ei.html
U.S, 2.09 (2006) https://www.cia.gov/cia/publications...k/geos/us.html
And heres a couple for the world, http://en.wikipedia.org/wiki/Image:F..._world_map.PNG

Jackson, if it's 2 per couple then the population would fall not rise, to double the population in one generation each couple would need to have 4 children. :wink:
sorry to burst your bubble megabrain but that's incomplete, to double the population every male and female would have to be matched up and then have 4 kids *urrgh horrible, all those monsters running aroundOriginally Posted by Megabrain

If you want to be precise, try starting your sentences with a capital letter. :wink:
i can go one better again :wink: , you missed two words out to make it grammatically incorrect it should be "you should try starting..."Originally Posted by Megabrain

And oh dang, I forgot my capitals and full stops again.![]()
My point being that (apart from third world countries - who simply reproduce because A) they have no birth control and B) there is nothing better to do out there.
So.....Whilst the population of third world countries is increasing, the population in the western world should in theory decrease because a lot of women these days are going for the "career" woman thing so they do not give birth, those that do may have one child or more commonly two. Two children from Two parents = equilibrium, and add the odd death or infertile person now and again into the equation and then you have a decline in the population, or should at least see one.

Yes I'd agree......my great great great aunt had 21 children. Sadly though, they all died on the titanic. :?Originally Posted by Megabrain
zero plus gain in world population requires births equal to deaths in total.
currently world wide we have 3.5 births for every death and a billion or so growth results every 12 years, with that 2 per couple average.
infant mortality rate in many African countries range up to 250 per 1000 children prior to one year old. in most industrialized nations the figures are around 6-10 per 1000.
the unfortunate truth is abortions are not figured in, which would make these industrialized nation look very bad. think the US alone has recorded about 30 million since its concept.
Leo; keep in mind religion and economy plays a very big role in how people perceive having children. many predominantly Catholic and Muslim Nations, all but ban any form of contraception. others and just as many give breaks for every child born, which is thought by the governing to improve economy.
People have sex the same amount of times all over the world. In third world countries, they generally don't use contraceptives but have a high death rate so the population has a small to large increase. In developing countries they generally don't use contraceptives but have access to modern medicines, heath care and consistent food and water supply so the population has a high increase. In the developed world we do generally use contraceptives and have access to medicines etc, so our populations have small increase or in some cases (Europe) the population is actually decreeing, and that includes immigration.Originally Posted by leohopkins
