Figure 3 shows that Williamson County households are generally skewed toward higher income levels, with the largest group earning above $200K and the second largest group earning just below that ($150-$199K). There is also a notable peak for the $75-$99K range, which includes the national median income level. Based on previous years of data, the concentration of households in higher income ranges has increased notably in the past five years, and is a large part of what has contributed to the overall increase in median household income for the County.
