Differentiate between simple and complex societies?

Using a broad examination of cultures, sociologists can classify them into two basic types: simple and complex. The designation is based on the economic considerations. Simple societies are generally smaller in population. The economy is subsistence based, meaning they only produce what they will use. Surpluses are very small and there is no motive to profit individually from economic activity. In the simple society, there is very little diversity in jobs or economic activity. Naturally, food gathering dominates simple societies. Innovation and change are almost non-existent.

Most civilizations today would be considered complex societies. There is a high degree of specialization in labor and a large variety different jobs. The diversity of jobs creates social stratification. Many jobs require advanced and unique skills because technology and innovation operate at a fast pace. Complex societies are motivated by surplus and profit with monetary systems of exchange.
