Final answer:
To find the percent decrease, subtract the initial population from the final population, divide by the initial population, and multiply by 100 to get the percentage decrease.
Step-by-step explanation:
To find the percent decrease, you need to calculate the difference between the initial population and the final population, and then divide it by the initial population. Then, multiply the result by 100 to get the percentage.
Let's apply this formula to the given problem. The initial population is 621,589 and the final population is 600,907.
Percent Decrease = ((621,589 - 600,907) / 621,589) * 100 = 3.33% (rounded to the nearest tenth).
