Executive Summary
Recent presentations to the Montgomery County Board of Education utilized a specific data visualization to argue that housing growth has “decoupled” from student enrollment. This chart has been cited as a primary justification for consequential infrastructure decisions, including the proposed closure of Wootton High School. As a data science professional with nearly two decades of experience in time series analysis, I have audited this visualization and found it to be methodologically invalid. The presentation relies on mismatched axes, hidden baselines, and a known statistical anomaly to manufacture a divergence that does not exist in the raw data.
