Car Dependency — Definition and What It Means for Your Income
The degree to which daily life requires car ownership due to limited walkability or transit access.
Car dependency describes locations where most daily activities — work, shopping, errands — effectively require car ownership due to limited walkability, sparse public transit, and land-use patterns that separate residential and commercial areas.
Why it matters
Car ownership costs an average of over $1,000/month (fuel, insurance, maintenance, depreciation). In car-dependent areas, this cost is effectively mandatory, while in walkable/transit-rich areas it may be optional.
Example
Houston, Dallas, Phoenix, and most Sun Belt metros have limited transit, making car ownership effectively mandatory — adding over $12,000/year to the cost of living regardless of salary.
