TPO debuts commuter‑flow tool as region adds residents; Knoxville surpasses 200,000
Summary
TPO staff demonstrated a new commuter‑flows digital tool using Census LODES data and recent population updates; the tool visualizes origin–destination commuter patterns across the 13‑county CSA and will be shared with board members.
Emily Jackson, research assistant for TPO staff, demonstrated a new commuter‑flows digital tool and summarized recent Census Bureau estimates showing population growth across the Knoxville combined statistical area. Jackson said the MSA population is about 968,000 and that the city of Knoxville has surpassed 200,000 residents.
Jackson walked board members through the tool’s features: an origin/destination map, scaled county destination dots, a commuter matrix for county‑to‑county flows and an industry‑employment breakdown. She explained the map symbology (white arrows: live‑and‑work in same county; blue arrows: outflows from Knox; green arrows: inflows into Knox) and showed examples, including approximately 6,200 estimated commuters from Knox to Sevier County and roughly 9,000 from Sevier to Knox County.
Jackson cautioned that LODES data have headquartering distortions (for example, ORNL employer addresses may be recorded in Anderson County even when workers report to Roane County), so the tool should be treated as a high‑level planning aid rather than micro‑precise counts. Board members requested the link; Jackson said the TPO will distribute the tool and handouts to the board.
Members discussed how the commuter data link to land‑use and housing policy: concentrating housing near job centers can shorten commutes and reduce congestion. Jackson said the tool and its underlying Census data can help identify economic interconnections and guide transportation and land‑use decisions.
