#### Transcript of Comparing the Life Expectancy and the Number of Children per

World Data Analysis Project
My Project
Comparing the life expectancy and the number of children per woman in the Netherlands from 1800-2012

Personal Connection: I lived there for 6 years
Perplexing Situation
It kind of goes all over the place in the graph but in general when the population increases the number of children per woman decreases which makes sense but at one point the number of kids just drops.

Conclusion
Thank you :)
Life Expectancy:
Mean: 55.45
Median: 52.78
Range: 41.05

The inner quartile means that the most of the life expectancy ages since 1800 are between 40 and 70. So the inner quartile range is 30.

The 1st quartile tells me that there weren't that many times were the life expectancy was less than 40 and the 3rd quartile tells me that there weren't that many times were the life expectancy was more than 70.

The range of my data suggests that the life expectancy in the Netherlands changed a lot over time because the range is really big.
Children per Woman:
Mean: 2.72
Median: 2.84
Range: 3.35

The inner quartile means that the most of the number of children per woman since 1800 are between 1.5 and 3.5. So the inner quartile range is about 2.

The 1st quartile tells me that there weren't that many times when the number of children per woman was less than 1.5 and the 3rd quartile tells me that there weren't that many times when the number of children per woman were more than 3.5.
Analysis
Analysis
Equation: y = -0.0835x + 8.406

The equation tells me that while the life expectancy is increasing the number of children per woman is decreasing but there's still the drop.
The line decreases while the population increases because people probably became more aware of the population and had less kids. It does surprise me how it makes an almost perfect line though.
But then I researched it and I learned that in the 1960's a women's liberation movement was going on in the Netherlands. I couldn't find much information about it but they probably started getting more jobs and therefore had less kids. There was also an abortion induction so the women had more of a choice about the number of children they had.
There are some parts that aren't perfect like a zigzag when world war II was, which makes sense. But the one thing I didn't understand was why there was a huge drop of children per woman between 1963 and 1983.
