Depends what if anything is being done to combat it.
One of the following is true:
- The numbers somewhat-accurately reflect the trend of employment
- Fraud levels were reduced 66x in one year
If it was the second one, that's a sufficiently massive reduction that news stories would be written about it. There would be stories about this great victory over fraud.
A quick search showed no particular anti-fraud measures or claims of effectiveness unique to that time period.
