What is the relationship between population size and growth rate?

Population size - it is the ACTUAL NUMBER OF INDIVIDUALS in a population. Growth rate - it can be express in a percentage; year over year change; measure of economic growth from one period to another.

The population size is the absolute number of people in a given area. The growth rate is the change in that number of people over a set period of time.

For example, the population size of your town could be 10,000 people. The growth rate of your town from the year 2000 to 2005 is a calculation of the number of people added to your town and the number of people your town has lost over five years.
