This layer displays commuting connections between US Census Tracts. Each line represents a minimum of 20 commuters between any two tracts. Direction is not displayed, with the exception of commuters who live outside of the state of Missouri and commute into the state. Data was aggregated from the census block level using the LEHD Origin-Destination Employment Statistics (LODES) dataset (2017). Some tracts have two connections (with each tract acting as an origin and destination for at least 20 commuters), and the lines are overlayed, others have only one connection and there is a single line connecting them, however this detail is not possible to discern with this dataset. Limitations of this dataset include the lack of directionality, and the overall abundance of commuters between any two tracts. Thus, this dataset should be used for visual analysis only.
