Does this mean that in the previous year there was 1/2 a rape and 1/2 an armed robbery?!? ---------- While we usually take the change relative to the starting amount rather than the ending amount, this does give us a pathological case. We have no way of stating the percentage change from 0 to 1 as a percentage of zero. I'm not a statistician, so I don't know what is usually done with such cases. Clearly in this case the change is of interest, but there's no good way to express it. scott preece ihnp4!uiucdcs!uicsl!preece
