As many as 10,000 visitors would come to the resort on a summer day by horse and buggy, railroad, trolley or excursion steamer. They came to enjoy the scenic view, to ride the Ferris wheel, attend daily concerts (double concerts on Sunday), rent row boats, watch outdoor movies, drink beer and dine on fine fare, including five types of whitefish netted daily in the adjoing bay. The resort's popularity faded in 1914, and the park was closed. In 1915 the land was subdivided into residential lots.
Whitefish Bay's emphasis on education began when farmers in the area demanded local schooling for children living in the area. In 1892, the 392 residents incorporated a village and built a school of their own on a triangle of land now known as Old Schoolhouse Park, across from today's public library. Unfortunately this school burned down due to a passing train which caused sparks to land on the wooden schoolhouse.
Whitefish Bay had a surge of home building in the 1920s and a bigger boom in the late 1940s and early 1950s. At its peak in the 1960s and 1970s, the village's population was over 18,000, but it is currently just over 13,500.
There were 5,457 households out of which 40.1% had children under the age of 18 living with them, 64.7% were married couples living together, 7.0% had a female householder with no husband present, and 26.4% were non-families. 22.9% of all households were made up of individuals and 8.4% had someone living alone who was 65 years of age or older. The average household size was 2.59 and the average family size was 3.09.
In the village the population was spread out with 29.4% under the age of 18, 3.6% from 18 to 24, 30.0% from 25 to 44, 25.1% from 45 to 64, and 11.8% who were 65 years of age or older. The median age was 38 years. For every 100 females there were 92.4 males. For every 100 females age 18 and over, there were 87.2 males.
The median income for a household in the village was $80,755, and the median income for a family was $95,744. Males had a median income of $63,011 versus $43,893 for females. The per capita income for the village was $39,609. About 2.4% of families and 3.2% of the population were below the poverty line, including 3.2% of those under age 18 and 4.7% of those age 65 or over.
The Archdiocese of Milwaukee maintains two Catholic schools in Whitefish Bay: Holy Family School and St. Monica School, each serving kindergarten through grade 8. In addition, the Sinsinawa Dominican Sisters, a Catholic Order, sponsor Dominican High School.
