INVESTOPEDIA EXPLAINS 'Expansion'

An expansion is one of two basic business cycle phases. The other is contraction. The transition from expansion to contraction is termed a "peak" and the changeover from contraction to expansion is a trough. Expansions last on average about three to four years but have been known to last anywhere from 12 months to more than 10 years. Much of the 60s was a time of expansion which lasted almost nine years.
