helpful background information

The issues surrounding population are pretty complex.  In order to understand them, we need to build a solid foundation.  We need to be able to define certain terms and concepts.  That was the purpose behind today's discussion, and the PowerPoint that came with it (the link to this PowerPoint has been posted).

Essential terms include:

• life expectancy
• crude birth rate (CBR)
• crude death rate (CDR)
• developing nations
• developed nations
• rate of natural increase (RNI)
• net migration rate (NMR)
• immigration
• emigration
• push forces
• pull forces
• total fertility rate (TFR)
