Why is this important?

Commute time measures the combined effects of several factors, including how close people live to their jobs and how much mobility the transport system provides. Lower commute times indicate that people are living closer to work and/or that the transportation system provides quality access and mobility. Commute times are influenced by various factors, including a personal preference for a specific residential location, availability of affordable housing within proximity of jobs, and availability of transportation modes [i]. Within a household with more than one worker, commute times can vary.

As housing and transportation are the two largest expenditures for the average household, availability of affordable, quality housing options within proximity to jobs or access to jobs are critical elements of household stability and wealth-creation [ii]. Lower income households tend to spend higher proportions of their income on transportation and housing costs combined [iii], and commuting time has emerged as the single strongest factor in the odds of escaping poverty [iiii]. Housing’s proximity to jobs can also affect the employment outcomes of residents; people who live closer to jobs are more likely to work, face shorter job searches, and have shorter spells of unemployment [ii].
