Since the percentage exceed 100% this isn't a measure of what percentage of people laid off fell into what age group. This likely then means that it's the percentage of people in that age group who were laid off, which means this is next to meaningless without more data. Since I doubt there are more people in the older categories to start with, I would expect their layoff percentages to be higher. Let's face it, if they had one person still working at 80 and he (or she) was laid off, that would indicate 100% rate for that age band. If we assume the impacted % for each age range represents 100 people (or any other same value for each range) then we get a starting distribution for each age range:
