The median income in Williams Bay has shown a notable downward trend over the past decade. The highest median income was recorded in 2015 at $73,377. From 2015 onwards, there has been a consistent decrease in median income, reaching $59,842 in 2022. Interestingly, the peak in median income (2015) coincides with a period of slightly higher diversity, with the Hispanic population at 10% and the white population at 87%. As the community became slightly less diverse in subsequent years, the median income also declined.

The population has fluctuated over the decade, with no clear long-term growth or decline trend. The population reached its lowest point in 2019-2020 at around 1,620 residents. There was a significant population increase in 2021 to 1,861, followed by a slight decrease to 1,811 in 2022. Despite these fluctuations, the overall population has remained relatively stable, hovering around 1,700-1,800 residents for most of the decade.

The low diversity and predominantly white population is consistent with many rural and small-town communities in the Midwest. The declining median income trend may reflect broader economic challenges faced by small communities. The relatively stable population, with a recent uptick, could indicate that Williams Bay has maintained its appeal as a residential area.

Williams Bay presents a picture of a stable, predominantly white community with moderate income levels. While it has experienced some economic challenges over the past decade, as evidenced by the declining median income, its demographic composition has remained largely unchanged. The community appears to be navigating subtle shifts within its established demographic and economic framework, rather than undergoing dramatic transformations.
