Aggregate travel time to work is calculated by adding all of the travel times (in minutes) for workers who did not work at home. Aggregate travel times of workers having specific characteristics also are computed. The aggregate travel time is subject to rounding, which means that all cells in a matrix are rounded to the nearest 5 minutes. (For more information, see "Aggregate" under "Derived Measures.")

This term appears in connection with several subjects: employment status, journey-to-work questions, class of worker, weeks worked in the past 12 months, and number of workers in family in the past 12 months. Its meaning varies and, therefore, should be determined in each case by referring to the definition of the subject in which it appears. When used in the concepts "workers in family" and "full-time, year-round workers," the term "worker" relates to the meaning of work defined for the "work experience" subject.

The data on time leaving home to go to work were derived from answers to Question 32. This question was asked of people who indicated in Question 28 that they worked at some time during the reference week, and who reported in Question 30 that they worked outside their home. The departure time refers to the time of day that the respondent usually left home to go to work during the reference week. (See "Reference Week.")
Beginning in 2006, the group quarters (GQ) population is included in the ACS. Some types of GQ populations may have departure time distributions that are different from the household population. The inclusion of the GQ population could therefore have a noticeable impact on the departure time distribution. This is particularly true for areas with a substantial GQ population.
