You state that your chart shows that "the higher the reported pay, the larger the gap." You really think so? The interval chart is organized by gap size. Looking at both plots, it looks to me like there're a couple outliers (Bergen and Tom's River) who have the highest pay and highest gap, but other than that there's not a clear trend. I'm just not quite sure I buy it.

I'd guess larger gap and actual salary are correlated, but you'd see that even if everyone's reported salaries were identical.

It's difficult to see it in the interval chart; that's why I also did a scatter chart. There, I used percentage difference, not actual difference, thereby controlling for reported salary. Obviously, the sample size is very small but the positive correlation is quite visible, to my eyes.
