Economic growth is not a steady phenomenon; rather, it tends to exhibit a pattern as follows:
1. Contraction
2. Recession
3. Expansion
4. Boom

For most people, a contraction in the economy can be source of economic hardship; as the economy plunges into a contraction, people start losing their jobs. While no economic contraction lasts forever, it is very difficult to assess just how long a downtrend will continue before it reverses because history has shown that a contraction can last for many years (such as during the Great Depression).
The longest economic contraction in the NBER database was the 65 month contraction from October 1873 until March 1879. By comparison, the contraction that began in 1929 and that initiated the Great Depression lasted 43 months from August 1929 until March 1933.
2. Recession: A significant decline in activity across the economy, lasting longer than a few months. It is visible in industrial production, employment, real income and wholesale-retail trade.
