Subcommittee on Census Data for Transportation Planning

Comparison of 1990 and 2000
Journey-to-Work Questions


Question
Changes
Number of Hours Worked
Last Week
Item deleted because there is no legislation requiring it, but usual hours worked each week in previous year is still on the 2000 census questionnaire.
Place of Work
No changes anticipated. 
Means of Transportation
No changes anticipated. 
Carpool Occupancy
Two fewer categories in 2000 (six vs eight in 1990).  The separate 1990 categories of "5 people" and "6 people" are combined into "5 or 6 people" for 2000.  The separate 1990 categories of "7 to 9 people" and "10 or more people" are combined into "7 or more people" for 2000. 
Departure Time
No changes anticipated. 
Travel Time
In 2000 we will capture three digits of travel time, not two digits.  Therefore, Census will not be constrained to show a maximum travel time of "99 minutes or more", but will be able to tabulate longer travel times more exactly. 
Vehicles Available
One fewer category in 2000 (seven vs. eight in 1990).  The top category will be "6 or more" in 2000 (vs. "7 or more" in 1990).

With the exception of tenure (owner/renter status), all the housing items that were collected on a 100 percent basis in 1990 have been moved to the sample questionnaire for 2000.  This means that these items will not be available for individual census blocks from the 2000 census.  The most detailed geographic level for which they will be available is the block group.  The Census Bureau's long-standing policy is that data collected on the sample questionnaire is not released for individual census blocks.  The items or questions affected are:
