6.11.8. Content Editing
After data collection was completed, any remaining incomplete or inconsistent information was imputed during the final content edit of the collected data. Imputations, or computer assignments of acceptable codes in place of unacceptable entries or blanks, were needed most often when an entry for a given item was missing or when the information reported for a person or housing unit on that item was inconsistent with other information for that same person or housing unit. As in other surveys and previous censuses, the general procedure for changing unacceptable entries was to allocate an entry for a person or housing unit that was consistent with entries for persons or housing units with similar characteristics. Imputing acceptable values in place of blanks or unacceptable entries enhances the usefulness of the data.

Private Vehicle Occupancy
The data on private vehicle occupancy were derived from answers to Question 26. This question was asked of people who indicated in Question 23 that they worked at some time during the reference week and who reported in Question 25 that their means of transportation to work was "Car, truck, or van." Data were tabulated for workers 16 years old and over, that is, members of the Armed Forces and civilians who were at work during the reference week. (See" Reference Week.")
Private vehicle occupancy refers to the number of people who usually rode to work in the vehicle during the reference week. The category, "Drove alone," includes people who usually drove alone to work as well as people who were driven to work by someone who then drove back home or to a non-work destination. The category, "Carpooled," includes workers who reported that two or more people usually rode to work in the vehicle during the reference week.
Limitation of the Data
Beginning in 2006, the Group Quarters (GQ) population is included in the ACS. Some types of GQ populations may have private vehicle occupancy distributions that are different from the household population. The inclusion of the GQ population could therefore have a noticeable impact on the private vehicle occupancy distribution. This is particularly true for areas with a substantial GQ population.
Question/Concept History
Beginning in 1999, the American Community Survey questions differ from the 1996-1998 questions only in the format of the skip instructions.
