The Data The data lists for each employee the Census block they live in and the block they work in. The data is anonymized to provide confidentiality, but can still be used to make visualizations of where individuals work and live. The map is made from the all jobs data set; so individuals who work multiple jobs are mapped for each job. Unemployed individuals are not mapped. Massachusetts is the only state that does not currently provide data as part of the program; so those who live there and work in other states show up, but anyone who works in Massachusetts is not included.
