Class 12/4, Summing Up Demographics

Today in class WE STILL DID NOT HAVE FOOD. But we finished going over demographics and we took a "comprehension check" which I don't know if is just a cover up name for a pop quiz?? I'm not even sure anymore what to expect.
Notes:

• Demographic Transition- refers to the transition from high birth and death rates to lower birth and death rates as a country or region develops from a pre-industrial to an industrialized economic system. Most developed countries have completed the demographic transition and have low birth rates; most developing countries are in the process of this transition. The major (relative) exceptions are some poor countries, mainly in sub-Saharan Africa and some Middle Eastern countries, which are poor or affected by government policy or civil strife, notably, Pakistan, Palestinian territories, Yemen, and Afghanistan.The model will track population changes that occur as a country begins to develop or industrialize. The model works from pre-industrial in stage 1, through development in stages 2 and 3, to post industrial stage 4. It allows us to compare where countries currently are in the transition to countries that have already gone through those changes which effectively can tell us what needs to change. 
• The more developed countries (core countries) are the industrialized capitalist countries on which developing countries (Semi-Periphery and Periphery) depend. Core countries control and benefit from the global market. They are usually recognized as wealthy nations with a wide variety of resources and are in a favorable location compared to other states. They have strong state institutions, a powerful military and powerful global political alliances.
