This article says that businesses created in the past 5 years have been a decreasing
percentage of the total number of businesses. The two you linked to say that
absolute business
creation rates are stable-ish and/or growing a bit.
Therefore, I suggest that one or both of the following are happening:
- The total number of businesses has been growing, while the number of new businesses remained stable.
- New businesses are failing (or being acquired?) more quickly, leading to fewer new businesses, despite roughly the same new-business creation rate.
