A population has 1000 individuals. Over a period of 1 year, 300 new individuals are born. Which equation shows how to calculate the birthrate of this population?

A. [tex]1000 \div 300 = 3.33[/tex]
B. [tex]1000 \times 0.3 = 300[/tex]
C. [tex]1000 + 300 = 1300[/tex]
D. [tex]300 \div 1000 = 0.3[/tex]

To determine the birthrate of a population, we use the formula:

[tex]\[ \text{Birthrate} = \frac{\text{Number of New Individuals}}{\text{Original Population Size}} \][/tex]

In this scenario:
- The original population size is 1000 individuals.
- The number of new individuals born over the period of 1 year is 300.

Substituting these values into the formula, we get:

[tex]\[ \text{Birthrate} = \frac{300}{1000} \][/tex]

After performing the division, we obtain:

[tex]\[ \frac{300}{1000} = 0.3 \][/tex]

Therefore, the equation that correctly shows how to calculate the birthrate of this population is:

[tex]\[ D. \frac{300}{1000} = 0.3 \][/tex]

So, the correct answer is:

[tex]\[ \boxed{D} \][/tex]
