SCATTERPLOT

This scatterplot shows the relationship between population and the gross domestic product (GDP) per state based on 2005 data. The red trend line reflects an average ratio for the US which generally indicates an increase in GDP relative to an increase in population. As you can see on the graphic, there are a few exceptions to this but there is a fairly strong, positive relationship between the two variables. The states that fall farther below and to the right of the average have healthier economic productivity.
