For the purposes of determining commuter patterns within the Catawba Commuter Shed, two factors were explored: where individuals living in the three Catawba Regional Economic Development District counties that are part of the commuter shed work, and, conversely, where individuals working within the three district counties that are a part of the commuter shed live.

For those individuals living or working within the counties of York, Chester, and Lancaster in 2019, there were 84,637 individuals who both worked and lived within those SC counties, 95,872 who lived in York, Chester, or Lancaster County and commuted out for their primary job, and 54,685 who lived outside these counties yet commuted in for their primary job.
