Chapter 30, Problem 1TC

Summary Introduction

To analyze:

The calculation of population growth rate and doubling time.

Given:

$\begin{array}{c}\text{Crude birth rate }\left(\text{CBR}\right)=\text{ 17}\\ \text{Crude death rate }\left(\text{CDR}\right)=\text{6}\end{array}$

Introduction:

Population growth rate can be calculated by subtracting the crude death rate from the crude birth rate divided by ten. The doubling time of a population can be calculated by dividing 70 by the annual population growth rate and it indicates the duration of time required to double the quantity of any value.
