Economic, Population and Historical Tax Data

Recently I wrote about one of MRSC’s new tools showing local sales tax rates and components. Today I’ll be covering another of our financial tools, this one showing recent tax and population data for every city and county in Washington.
Our Population and Tax Data page contains several files with information on property taxes, sales tax distributions, and population from 2010 to present. This includes the annual population estimates released by the Office of Financial Management (OFM) as well as data from the Department of Revenue (DOR) and Office of the State Treasurer (OST) on locally assessed values, levy rates and amounts, current maximum statutory levy rates, and sales tax distributions for each jurisdiction.
Using this data you can easily examine basic financial information and trends within your jurisdiction since 2010 or compare your jurisdiction to nearby or peer jurisdictions.
We’ll continue updating this information several times per year as new information is released by OFM, DOR, and OST. The next update will be in late June or early July with OFM’s new population estimates.
Using the City/Town Data
For cities, each file contains information on:
- Population estimates
- Locally assessed values
- Regular levy rate per $1,000 assessed valuation
- Current statutory maximum levy rate for each city
- Regular levy amounts (total revenue), including levy lid lifts
- Excess/bond levy amounts (total revenue)
- Total levy amounts (regular levy plus excess/bond levies)
- Sales tax revenues
We provide a snapshot of the most recent data in each category (PDF or Excel) or historical data from 2010 to present (Excel). The Excel spreadsheets allow you to sort or filter any of the values, so you can quickly and easily compare your jurisdiction to nearby or peer cities.

Using the County Data
The county data is similar to the city data, but there are a few differences due to the unique nature of counties. For counties, each file contains information on:
- Population estimates (total and unincorporated)
- Locally assessed values
- Regular levy rate per $1,000 assessed valuation
- Current statutory maximum levy rate for each city
- Regular levy amounts (total revenue), including levy lid lifts
- Excess/bond levy amounts (total revenue)
- Total levy amounts (regular levy plus excess/bond levies)
- Sales tax revenues
As with cities, we provide a snapshot of the most recent data in each category (PDF or Excel) or historical data from 2010 to present (Excel).
In addition, all of the assessed value and levy information includes breakdowns for the general fund and the county road fund, as well as conservation futures funds and diverted road funds for those counties that use them. (Levies for the general fund and conservation futures fund are assessed countywide, while county road levies are only assessed in unincorporated areas, which is why they show different assessed valuations.)
We’ve also indicated counties that are using a road levy shift to increase their general fund levy rate beyond the normal maximum of $1.80 per $1,000 AV while reducing their road levy rate, although this is not very common.

Final Thoughts
Download these datasets and more at our Population and Tax Data page.
You can also learn more about property taxes, sales taxes, road levy shifts/diversions, and other revenue sources in MRSC’s City Revenue Guide and County Revenue Guide. While we have made some recent updates to these publications, please note that we are starting a comprehensive review and re-write of both publications, to be released this coming winter.
