July 29, 2020 (Salt Lake City, Utah) – Research from the Kem C. Gardner Policy Institute shows Utah’s relatively young population is contributing to a lower COVID-19 death rate than the nation as a whole. As of July 14, 2020, the CDC COVID Data Tracker reported the Utah and U.S. per-capita death rates as 7.0 and 41.3 per 100,000, respectively, a difference of 34.3. Using various decomposition methods, demographers at the Gardner Institute estimate that about 8 of those deaths per capita are attributable to Utah’s younger population, with the remaining difference being a result of other factors.
“In many ways, this anaylsis is more exploratory than definitive, since the provisional data are still so fresh,” said Mike Hollingshaus, senior demographer at the Gardner Institute and lead author of the brief. “But, it provides an alternative outlook on the data. This different way of thinking changes how policymakers view per-capita rates and recommends a nuanced approach to the decision-making process.”
The analysis provided instructive, but still preliminary answers to three questions:
- What would Utah’s COVID-19 death rate be if its population had the same age structure as the U.S. population? If Utah had the same age structure as the U.S., its death rate would rise by nearly 50% to 10.1 per 100,000.
- What would the U.S. rate be if its age structure were identical to Utah’s? If the U.S.’s age structure were similar to Utah’s, its death rate would drop by nearly one-third to 28.3 per 100,000, and deaths would have numbered under 100,000 instead of over 130,000 as of July 14.
- How much of Utah’s lower death rate is the result of the state’s younger population? About one-quarter of Utah’s lower death rate is attributable to its younger population. The majority (three-fourths) is due to other factors.
In addition to Utah’s young population, other socioeconomic, environmental, and demographic characteristics likely play a role in explaining some of the remaining differences in the state’s death rate. The state could also have a lower per-capita rate due to better prevention, response, and treatment; but that conclusion is not justified until these other factors have been accounted for in statistical models.
“Utahns should continue to proceed with caution and remember that demographics matter when combating the profound impacts of COVID-19 on our society,” said Pamela Perlich, director of demographic research at the Gardner Institute. “We hope our research can help decision-makers wisely interpret and act upon population-level metrics as they develop effective policies to combat the pandemic.”
