Research data for The Impact of Urban Form on Vehicle Ownership

One of the attractive features of the ACS data is the ability to ask several types of transportation questions, to millions of Americans. I exploit this fact in my new research results on the effect of land use patterns on vehicle demand. This article is forthcoming in the journal Economics Letters.

The data and code for this study are hosted at Open ICPSR. The Inter-University Consortium for Political and Social Research was conceived in the 1960s as a place where universities share data, and has thus been in the data game for a long time. In the past their data archiving has been more curated, and the new "Open" ICPSR is a new and exciting development. I plan to continue to use OpenICPSR to archive the research data for my projects.

Here is the abstract:

The Impact of Urban Form on Vehicle Ownership

Driving is the single biggest source of household carbon emissions, and land-use policies that encourage higher density are motivated in part by findings of lower vehicle ownership rates in compact areas. However, many previous estimates suffer from self-selection bias. Utilizing an indicator variable for the presence of same gender children in the household as an instrument for population density, I find a 10% increase in density causes a -0.012 decrease in the size of a household's vehicle fleet.
