As the total U.S. GDP has grown over the years—from $7,414.7 billion in 1995 to $25,462.7 billion in 2022—the For-Hire Transportation GDP has also increased, rising from $231.7 billion in 1995 to $815.0 billion in 2022. Despite this growth, the For-Hire Transportation sectors share of the total U.S. GDP has fluctuated between 2.7% and 3.7% during this period. This data indicates that while both the total U.S. GDP and the For-Hire Transportation GDP have expanded at a similar pace, the substantial increase in the For-Hire Transportation GDP over these 28 years has not directly driven the rise in the overall U.S. GDP. However, despite this, there remains a clear correlation between the Total U.S. GDP and the For-Hire Transportation GDP. The data reveals a positive relationship between these two variables: as the Total U.S. GDP increases, the For-Hire Transportation GDP rises as well.
The scatter plot illustrates a positive correlation between the Air Transportation GDP and the Total U.S. GDP. Over the years, as the Total U.S. GDP has grown, the Air Transportation GDP has shown a similar upward trend. Although there are some notable outliers, the overall relationship between these two variables remains clearly positive.
The scatter plot clearly demonstrates a positive correlation between the Truck Transportation GDP and the Total U.S. GDP. As the Total U.S. GDP increases, the Truck Transportation GDP rises accordingly. Notably, there appear to be no visible outliers, as the data points closely align with the potential line of best fit.
From the scatter plot, we can see a correlation between the United States total GDP and the GDP that is derived simply from For-Hire Transportation. Throughout all the sampled total GDP’s from the years, as the total GDP in the United States increased, the GDP for For-Hire Transportation increased in a similar way. From this, we can conclude that the increase of total GDP has an effect on the GDP created through For-Hire Transportation.
The line graph represents the percentage of Total U.S. GDP that For-Hire Transportation contributes to. From the graph, we can see that the percentage of GDP from the United States that For-Hire Transportation produces is usually around 2-4%. Even though this percentage might not be much, it still demonstrates a correlation as this percentage remains somewhat consistent as the Total GDP in the United States increases.
