Population growth rate is an important factor to consider when looking at the past and future of a population. In this lesson, you'll learn how to The national population growth rate is determined by calculating the difference between the factors contributing to population increase (CBR and immigration) and the factors contributing to population decrease (CDR and emigration), all divided by 10. Use the equation for National Population Growth: For example, if you hear that the population of your town is growing by 2% per year, that means it will double in just 35 years! (70/2=35) It works in reverse, too: divide 70 by the doubling time to find the growth rate. If you hear that U.S. population is due to double in 70 years, you know that it's increasing at 1% per year (70/70=1). The formula for exponential population growth is N=N 0 e rt where N 0 is the starting population, e is a logarithmic constant (2.71828), r is the rate of growth (birth rate minus death rate), and t is time. If you plot this equation, you see a curve arching upward over time as the population increases exponentially, assuming no change in the rate.

The population of Lane County grew 12 percent between 1980 and 1990 or at an rate of 1.2 percent annually. 2. Calculating Average Annual (Compound) Growth Rates. Another common method of calculating rates of change is the Average Annual or Compound Growth Rate (AAGR). APES Unit 5: Populations Page 1 (1)20 (2)30 (3)40 (4)50 (5)60 1.If a population of 500 has an intrinsic growth rate of 5% a year and its environment has a carrying capacity of 3,000, what is the least amount of years it take for the population to reach its carrying capacity? (1)a decrease in wars age structure of the population - the number of women of child bearing age affects the rate of population growth. total fertility rate - Total fertility rate (TFR) is the average number of children that each woman will have in her lifetime and affects the birth rate. Population Calculation Worksheet. You will need to be familiar with these equations for your Unit 5 Exam and the AP Exam. Population density ( population ) What would happen to the population growth rate of a country that maintains a high crude birth rate of 32 but was able to reduce their crude death rate from 28 to 12? immigration rate.
