Find the decrease in population by subtracting the new population from the original population. The decrease is 1,230 minus 1,040 equals 190 people. This is the actual number lost during the epidemic.

Calculate percentage decrease using the formula: decrease divided by original × 100. Substitute values: 190 divided by 1,230 × 100. First divide 190 by 1,230 to get approximately 0.15447.

Multiply by 100 to convert to percentage: 0.15447 × 100 equals 15.447 percent. Round to three decimal places to get 15.450 percent decrease in population.
