The excess of births over deaths in a year per 1000 individuals is called growth rate

Answer

### Step-by-Step Solution:

1. **Understanding the Terms**:
- The question refers to the concept of "growth rate," which is a measure of how much a population increases or decreases over a specific period, typically expressed per 1000 individuals.

2. **Defining Births and Deaths**:
- In this context, "excess of births over deaths" means we are looking at the number of births that occur in a year compared to the number of deaths in that same year.

3. **Calculating the Growth Rate**:
- The growth rate can be calculated using the formula:
\[ \text{Growth Rate} = \frac{\text{Number of Births} - \text{Number of Deaths}}{\text{Total Population}} \times 1000 \]
- Here, the total population is considered to be 1000 individuals for the purpose of this calculation.

4. **Interpreting the Statement**:
- The statement in the question asserts that the excess of births over deaths in a year per 1000 individuals is indeed referred to as the growth rate. This aligns with the definition provided in the previous steps.

5. **Conclusion**:
- Therefore, the statement is correct. The excess of births over deaths in a year per 1000 individuals is accurately described as the growth rate.
