Following the publication of the Office of Financial Management’s 2019 Population Study, in the August 15 edition of The Manifest, we take a look at where Washington State is growing (and not growing), over the past nine years. Below, further data insight shows where the increases and decreases are, along with the highest and lowest growth in sales tax distribution by county.
