Hello all,

Within the last year, CDC Wonder stopped providing age-adjusted death rates at the county level. This is what is posted as the reason on CDC Wonder:

• Standard age-adjusted rates (calculated with standard populations) are only available for Ten-Year Age Groups.
• Age-adjusted rates are not available at the county level for analysis of mortality by Single Race, including analysis of Urbanization categories for counties, because the populations are weighted to the 10-year age groups, and county-level population estimates are not available for the "<1 year" and "1-4 years" age categories.

However, some states, particularly those more densely populated, have published multi-year (ex: 2020-2023) age-adjusted death rates for the leading causes of death, including stratified rates by race when the population is large enough. My questions are.

1. Is it a resource/staffing issue that allows some states to make these calculations and not others?
2. Are there other factors (ex: population density, local demographic data collection, use of other age proxys, etc.) that allow this to be possible in some places and not others?
3. Does CDC Wonder's description of the Census changes imply that age-adjusting death rates will not be reliable below the state level analysis during this 10 year period?

Any and all insights are greatly appreciated.

Dear Danielle,

I took a look and the NCHS mortality vital stats dataset that I referenced and it only goes to the state level.  The SEER database has county level all cause mortality data.  You need this to calculate relative survival. You need to sign a data use agreement to access the SEER data.  I don't think that you can access the data for commercial use without special permission.

SEER  has death data for County x Age x Sex x Race x Hispanic for 2019-2023.  You can't download all variables at the same time.  You can do State x Age x Sex x Race x Hisapanic and then adjust the state level table by the county marginals for example by County x Age x Sex

If you are using the data in a for-profit commercial context you need a commercial license.  Email seerstat@imsweb.com and ask about details.
