An MOE is the difference between an estimate and its upper or lower confidence bounds. Confidence bounds can be created by adding the MOE to the estimate (for the upper bound) and subtracting the MOE from the estimate (for the lower bound). All published ACS MOEs are based on a 90 percent confidence level. 2005-2009 Estimate Range: 29.8 to 30.4 (30.1-0.3) to (30.1+0.3) 2000 Estimate Range: 27.0 to 27.4 (27.2-0.2) to (27.2+0.2) Difference: 2.9 (30.1-27.2)
