Question: How does the social environment affects young people?
This question was posed to understand how social economic status affects the growth and behavior of young people. I found a data that was hosted by Drexel University here. The nitpick I have with this dataset is that it is not as modern as I wish it was. (1990-1991) However, it was the best I could locate with the details I am interested in.
I was able to download the dataset in .CSV format. I had to remove the first few rows so that Tableau was able to parse it. I also normalized certain fields by the total size so as to get percentage values.

## First Visualization

My first hypothesis was that in States with a larger percentage of High School Graduates, we can expect to see a lower percentage of births to single teen mothers.
A simple dual axis plots rejects this hypothesis . The graph shows that the correlation between percentages High School graduates and births to single teen mothers is positive. One possible explanation is that the data for births to married teens is missing.

## Second Visualization

Intrigue by the varying percentage birth rates to single teens, I investigated how poverty might affect this.

In this visualization, we can see clearly see that there is a negative correlation between the two. One compelling reason might be that as poverty rates increase, women might be forced by circumstance to terminate the pregnancy. It might be that poor nutrition causes a higher incidence of miscarriages.

## Third Visualization

The point of the second visualization was to show the correlation between the two factors. In this revision, the States are removed and encoded as data points. This visualization shows the correlation effectively with a trend line. Although we lose the ability to compare results over States, the relationship is clear by observing the gradient of the trend line. This is very useful especially when the the axis are loosely correlated, which will result in a very messy visualization if the first technique was used. Since the previous visualization will require the States to be sorted differently for each factor, it will be confusing to use it in a multiple.

## Fourth Visualization

Question: How does the social environment affects young people?

In this visualization we can see how social-economic factors can influence the development and behaviour of teens. The 2 factors are namely poverty and single parental families. Each data point in the visualization represents a state and the collection of the points represents the trend within America.
From the visualization, we can observe that if the community has a high percentage of teens in poverty, it tends to have a slightly higher juvenile crime rate. Also, if the community has a high percentage of teens in poverty, the percentage of teens who graduate from High School decreases. It is intriguing to observe that if the community has a high percentage of teens in poverty, the percentage of births that belong to single teens decreases.
In communities where there is a large percentage of teens who grew up in a single parent family, there is corresponding high rate of juvenile crimes. Also, as the percentage of teens who grew up in a single parent family increases in a community, the percentage of high school kids who graduate decreases correspondingly. It is interesting to observe that as the percentage of teens grew up in a single parent family increases the percentage of births that belong to single teens decreases rapidly.
