post 4- relations

I created a relation ship between life expectancy and child per women and it turned out to be linear. I found that the shorter your life expectancy the more children you are to have. This could be because in countries with where people are not living as long the child mortality rate is also low, so these families perhaps feel that even though they have so many children, a number of them could die, so in the end the actually amount of grown adults from one women is not the same as infant to women and therefore to have a next generation they give birth to multiple children. Another possible reason for this is that create a child and then give birth is very stressful and damaging on a women's body, so with every child, a women's life shortens.

Interestingly enough if you go back 200 hundred years ago the age expectancy doesn't correlate with the number of children, but it is the same statistic as now for some poorer countries. women are dieing at around 40 if they are having 7 to 8 children. even though most countries have developed to have a higher life expectancy the trend seems to be that women can't live past 40 if they give birth to 7 children.
