Maximum absolute prevalence differences between 2000 Behavioral Risk Factor Surveillance System (BRFSS) and 2000 Decennial Census estimates for six sociodemographic factors: values before and after adjustment for non-response/non-coverage (NR/NC). Medians and interquartile ranges (IQR) for the prevalence differences reported as well as indicators for whether the differences were statistically significant (p<0.05)

• * State-level analyses included 50 states and DC. Number of counties for county-level analyses varied due to missing data and minimum sample size requirements (gender: n=732; race: n=730; age: n=732; ethnicity: n=729; income <\$15 000:, n=638; marital status: n=730).

• BRFSS significantly different from Census at p<0.05.
