Hi,
We are trying to reconcile the percentage of persons with disabilities in the 5-year 2015-2019 ACS for Colorado with the percentage of persons with disabilities in the 2019 BFRSS.
The percentage from ACS table B26108 shows that approximately 11% of all persons and 13% of persons age 18+ have disabilities. In contrast, the BFRSS percentage for "Calculated Disability" is 20%.
The BRFSS is a survey of persons age 18+
I constructed a confidence interval around the ACS estimates, but the BRFSS value is outside these bounds.
Does anyone have ideas about why these two estimates differ?
I'd appreciate any thoughts about how to reconcile these differences.
TIA

Here's a brief summary of non-response bias and weighting differences identified in 2013: www.mathematica.org/.../using-american-community-survey-disability-data-to-improve-the-behavioral-risk-factor-surveillance
