Jobs, healthcare and education can exist in the same metropolitan area without being practically reachable by every resident.
The average American commute took 27.2 minutes each way in 2024, up from 26.8 minutes a year earlier, according to the U.S. Census Bureau’s American Community Survey: https://www.census.gov/topics/employment/commuting/guidance/acs-1yr.html. More revealing, 9.3% of commuters traveled at least an hour one way, compared with 8.9% in 2023. Those figures measure trips made, not the jobs people never applied for because the trip was impossible. Yet they establish the practical question behind access: when a metropolitan area announces new employment, training or services, how many residents can actually reach them on the schedule required?
The University of Minnesota’s Access Across America research offers a more useful measure than simply counting regional jobs: https://www.cts.umn.edu/programs/ao/aaa/auto/auto2024. Its 2024 automobile-access study calculates how many positions workers can reach within a given travel time, accounting for congestion. In Los Angeles, more than 1.5 million jobs were within a 30-minute drive under the study’s accessibility measure, but peak-hour congestion reduced the jobs accessible to the average worker by 64% relative to free-flow conditions. That is not a finding that 64% of jobs disappeared; it shows how traffic changes the practical reach of existing employment. A city can gain jobs while some residents experience a shrinking set of realistic options.
The transportation mode available to a worker changes the calculation again. Census data show 69.2% of workers drove alone in 2024, while 3.7% used public transportation and 13.3% worked from home. These national averages conceal neighborhood variation, and they do not measure whether transit is available at the hour someone needs it. Consider a hypothetical hospital aide offered an early shift across town: a bus route may connect both locations during the day yet fail to provide a reliable arrival before dawn. The job exists, the applicant qualifies, and the metropolitan economy appears to be growing. None of those conditions guarantees a workable commute.
Housing can turn the problem into a trade-off with no inexpensive choice. A household may move farther from a job center to lower its rent, only to absorb higher fuel costs, vehicle repairs, childcare expenses and unpaid travel time. A worker without a car may remain near transit but face a narrower selection of affordable housing. These are possible household-level consequences, not effects measured by the two studies cited here. Their importance is that employment, housing and transportation decisions interact, while government agencies and economic-development plans often evaluate them separately. A lower monthly rent is not necessarily a lower total cost of accessing work.
The same barriers extend beyond payroll. A community clinic can be within county limits and still be difficult to reach without a vehicle. A tuition-free training program may require repeated trips that a participant cannot afford to miss. A public hearing scheduled downtown at a conventional hour may technically welcome every resident while favoring those with flexible jobs and transportation. Access should therefore be tested against the actual conditions of use: travel time, service frequency, fare or fuel cost, opening hours, accessibility for disabled residents and the reliability of the return trip. A destination on a map is a starting point, not proof that a service is usable.
A more serious response would coordinate housing approvals, workforce investments and transit schedules around measurable journeys. Agencies could publish the number of jobs reachable within 30 or 60 minutes by different modes, compare conditions before and after service changes, and identify where new housing would connect residents to employment rather than isolate them from it. Employers could disclose shift times early enough for applicants to evaluate transportation; training providers could pair enrollment with travel assistance or distributed locations. The University of Minnesota research demonstrates that accessibility can be measured. The remaining challenge is to make those measurements consequential when budgets and locations are chosen.
SSC’s assessment is that opportunity should not be judged only by the number of jobs announced, clinics opened or classrooms funded. It should also be judged by who can use them without sacrificing disproportionate time and money. A region can celebrate investment while leaving residents unable to convert that investment into a paycheck, an appointment or a credential. Better geography policy begins when leaders stop treating proximity as participation and start measuring the journey between an available opportunity and the people it is supposed to serve.
