For example, the SAIPE program’s 2007 estimates utilized federal tax return data for 2006, which were filed in 2007, and were available to our program in 2008. The 2007 SAIPE estimates also used data from the 2007 ACS which were collected throughout 2007, tabulated and made available to the SAIPE program in August 2008.

A confidence interval is a range of values that, with some level of certainty, contains the true value the estimate is approximating. For example, each state and county estimate is listed with a 90-percent confidence interval. This means that for a particular estimate, if we carried out our estimation procedure and creat
