Changes or improvements from one year of a survey to the next are common in any ongoing survey operation. Some changes or improvement s can result in apparent differences between two years that subject matter experts identify as potentially more influenced by the survey changes rather than by actual change in the item measured. The American Community Survey implemented a variety of changes in the 2008 qu estionnaire. These changes may have impacted the estimates of several variables, specifically the estimates of Hispanic origin type, nativity, race, and language spoken at home. This docum ent is intended to provide data users with information on the changes observed between the 2007 and 2008 data for these selected variables, and to illustrate th e impact on the observed differences between the annual results that may be attributable to the surv ey changes. As a result, we recommend that data users should treat the measured change between the 2007 and 2008 results with caution.
