A Methodological Approach to Small Area Estimation for the Behavioral Risk Factor Surveillance System


The scatterplot shows the ACS 1-year (2013) estimate of the uninsured population aged 18 to 64, plotted against the BRFSS SAEs of the same indicator for the 817 counties where ACS 1-year estimates were available. The plot indicates the overall high correlation of the indicator between the 2 data sets.
