The vast majority of cases are clumped together at the lower end of the scale, with most falling below 100,000. There are, however, a few cases in the 500,000 range and even beyond (too few to even be visible without modifying the histogram). These very high values for only a few cases have a significant effect on the mean but little or no effect on the median, making the median a better indicator of centeral tendency in this example.
