Population distributions change substantially over time in major metropolitan areas. Knowledge of these variations by time of day, day of the week and other time periods can be helpful to disaster planners who need to prepare response plans to earthquakes and other disasters that will injure and kill large numbers of people. Computer graphics can display data that describe these changing population patterns in ways that can be more easily comprehended than page after page of printed numbers. Several different illustrations of 3‐D population density maps drawn by the ASPEX computer program are presented. Each illustrates a guideline that can be used to prepare maps that deal with the many ways of looking at urban population density distributions and their temporal changes. Those maps can help disaster planners gain a realistic perception of population density distributions by enabling them to see what cannot be seen from the actual physical structure of a large metropolitan region.
