Highlights from the 2014 NSTA Convention

Understanding Basic Demography: What is Birth Rate and Death Rate

There are two statistics that are fundamental in the study demography - birth rate and death rate. It is essential for students to have a working knowledge of these two figures, as they serve as the building blocks for understanding more complex population concepts like growth rate, doubling time, and more.
