The question says the rates of change in relation to the number of jobs. That’s what I was working on. Take 1999 to 2000, for example. The difference is under 2000 in about 40000 which is only about 5%. The average rate of change is less than that. It takes 10 years for the number of jobs to go from 38,800 to 43,100. That’s an average of 430 per year. The average number of jobs is around 41000 so 430/41000=1% approx which is small.
