Since its founding, the United States has gone through 49 recessions.
The average period of time between recessions is less than 4 years. Since World War II, that figure has been 58 months, or close to 5 years.
In America’s history, the longest expansion lasted 120 months, or exactly 10 years.
The last recession ended in June 2009. The next recession will most likely happen before January 2021.
