... The debris impact footprint is affected by many factors, including deorbit maneuver accuracy, range of debris ballistic coefficients, breakup altitude, breakup /\v, atmospheric density, winds, and debris aerodynamic lift. Assuming a successful reentry mission, NASA analyses have concluded that the ISS dispersed debris footprint could be as large as an ellipse measuring 300 km by 5,370 km (162 nmi by 2,900 nmi)

... The National Aeronautics and Space Administration should undertake a thorough analysis of International Space Station reentry operations, including ranges of uncertainty associated with the multiple variables of reentry operations. The analysis could take the form of a Monte Carlo simulation of reentry operations and projected impact areas to characterize the hypothetical potential for property damage or casualties.
