RE: [CTPP] RE: No Car but Drive Alone to Work - [SPAM] - Found word(s) list error in the Text body

Unless I'm seriously mistaken, there is no question about cars owned in the ACS. Question #9 (from the ACS 2008 questionnaire), as follows, asks about "automobiles...kept at home for use by members of this household: 9. How many automobiles, vans, and trucks of one-ton capacity or less are kept at home for use by members of this household? Questions 30 and 31 do ask about means of transportation to work, although neither one refers to the ownership of the vehicle: 30. How did this person usually get to work LAST WEEK? If this person usually used more than one method of transportation during the trip, mark (X) the box of the one used for most of the distance. 31. How many people, including this person, usually rode to work in the car, truck, or van LAST WEEK? As a personal observation, many automobiles are leased, not owned, and that may explain any unusually high numbers if indeed there are questions that allow a correlation between car ownership and means of transportation to work.

Again, as Ed notes, having a company car (that is not owned by the commuter) might create a head-scratching moment for the respondent, leading to this result in a small percent of cases. Keep in mind too, that the question asks how the respondent got to work the majority of days last week, which could have been a non-standard work week for the respondent, such as when they go to a conference in a distant city. For us, that has shown up in our dataset as "walking to work" at a job on the other side of the continent (e.g., from the hotel room to the conference room?), or traveling by ferryboat when none serves our community. Sometimes the best strategy for dealing with the anomalous outliers is to read the exact wording of the question, imagine potential oddball scenarios that could create them, then ignore them with a clear conscience.

He put together a table from the 2006-2008 ACS showing mode of journey to work by vehicles owned and came up with surprisingly large numbers who do not won a car yet drive alone to work. No doubt, there are a few people who fit this category but my guess is that this largely is the result of either people misunderstanding the question or some sort of coding problem. Here is an excerpt from his email ( the Cambridge here is Cambridge, Massachusetts): I'm looking at ACS data and specifically at cities and percent workers have no car available. From that I'm then looking to see how those workers get to work. The attached worksheet shows my work. What is strange is that it shows for Cambridge that 6.6% of people without a car available drove alone to work. The percent is similar to Boston. And NYC has 3.4% of workers with No vehicles available driving alone to work. So, the question is, how can someone without a vehicle drive to work alone? Do you have any ideas on this? It could be someone doesn't own a vehicle, but drives a friend's car to work. Or has no car of their own, but uses a company car to get to work. But seems like a high number for this. Can anyone shed any light on this?
