1. Global cities are the centers of the global flows of information and capital.  Several tiers of global cities offer varying levels of business services.

2.Some small countries offer offshore financial services, which attract investors because of low taxes and extreme privacy.  Developing countries also specialize in back-office operations, also called business-processing outsourcing.

3. Basic industries export primarily to consumers outside the settlement; they are the principal source of growth and wealth for a settlement.  Some  settlements attract a disproportionate share of talented individuals

4. A clustered settlement is an  settlement in which houses are close together

5. The earliest settlements provided consumer services, especially as places to bury and honor the dead. Early settlements were also places of education and production of tools.  Early public services included governance and protection of dependents.

6. Prehistoric: Fertile Crescent of SW Asia and North Africa. Ur is a well documented settlement here, it means "fire".

Ancient: Knossos, Troy, and Mycenae. These settlements provided government, military, and protection to their hinterlands.

Medieval: These were run by lords who gave charter lands to people in exchange for military service.

7. Urbanization is the process by which the population of cities grows. Its two dimensions are the increase in the number of people living in cities and the second is an increase in the percentage of people in cities.
