This video is from Chapter 4 in the Book “Biology: The Dynamics of Life”. It talks about population growth as it relates to Human Populations. It’s a basic introduction to the field of demographics (human population growth), and shows the 3 factors that demographers are concerned with: Growth Rate, Age Structure and Geographic distribution.

Growth Rate is determined by Birth and Death rate. Age structure has to do with the proportions of a population at the different age levels, and geographic distribution deals with the topics of immigration and emigration.

Outline of the lecture:

• Demography
• Growth Rate
• Age Structure
