The urban element is comprised of Parts 1,2, and 3.
Part 1 contains data for housing units, households, persons
and workers located in or living in the region.
Part 2 contains tabulations by area of work. It also
provides data on people who worked in the region, such as information
on the mode of travel to work, type of work, as well as the amount of
time required to get to work.
Part 3 provides tabulations of residence area by work area

totals on where individuals live in a region and where they reported
that they work. The data provided also depicts if the individual left
