To calculate the unemployment rate, use the formula:
\[ \text{Unemployment Rate} = \frac{\text{Unemployed}}{\text{Labor Force}} \times 100 \]
In your case:
- Total population = 5,000
- Labor force = 4,000
- Employed = 3,500
First, calculate the number of unemployed residents:
\[ \text{Unemployed} = \text{Labor Force} - \text{Employed} = 4,000 - 3,500 = 500 \]
Now, plug the numbers into the unemployment rate formula:
\[ \text{Unemployment Rate} = \frac{500}{4,000} \times 100 = 12.5% \]
Therefore, the unemployment rate is 12.5%.
