The city of Lake Saint Louis is bordered by I-70 to the north and I-64 bisects the south end with a recent addition of Hwy 364 as a new connector highway throughout St. Charles County. A large shopping center is just north of I-64 and a retail district lies directly to the south. Workers routinely travel both interstate corridors west to the Wentzville GM Plant and to major employers in O'Fallon and other points east. Additionally, the population of our city is greater than indicated from the 2020 census results. As of 2020, the population of the city shows 16,707. Due to these factors, calculating a disparity index based on comparison of ethnicity of drivers stopped with the ethnicity of the city's population may be misleading due to the transient traffic.
