2. Understanding the Surveys Sample: 1 in 6 of all households. (15.32 million households) Coverage: Whole country – 3140 counties Point in time Survey –Reference period: April 1, 1990 Group quarters’ population included Sample: 700,000 households Coverage: 1203 counties Rolling Survey Conducted over 12 months Group quarters’ population NOT included 1990 Decennial Census 2000 ACS: Census 2000 Supplementary Survey (C2SS)

3. Understanding the Surveys Mode to work: “usual last week” Mode to work: allows only for ONE response C2SS includes only workers in hhlds (does not include workers in Group Quarters) 1990 CTPP tabulated travel time for all workers— households and group quarter information cannot be separated. 2000 ACS tabulated travel time only for workers in households.

Carpooling declined from 13.4 percent (1990) to 11.2 percent (2000) of all workers. Transit retained 5 percent share between 1990 and 2000. In numbers, workers using transit for their JTW increased 7.7 percent over the 10-year period (1990 to 2000).

Note: Some of this difference may be due to coding changes (of trips > 99 minutes) between 1990 and 2000. The increase may be closer to 1 minute and 24 seconds. 14.2% of workers now commute more than 45 minutes to work (1990, 12%) 29% of workers now commute less than 15 minutes to work (1990, 31.4%) Note: “Worked at home” was excluded from “commute less than 15 minutes”
