Jobs-housing balance refers to the distribution of employment relative to the distribution of workers within a given geographic area. Implicit in the concept is a broad mix of housing types to accommodate households (workers) of a range of income categories. A community is considered balanced when these distributions are approximately equal and when available housing choices complement the earning potential of available jobs. The central concern of jobs-housing balance as it relates to transportation policy is the journey to work. The concept implicitly assumes that workers choose to work as close to home as possible (or that workers choose homes as close to their jobs as possible). If a given area has a much greater concentration of employment than resident workers, workers must be drawn from other areas, leading to longer commutes. Similarly, if resident workers greatly outnumber job opportunities, they must seek jobs in other more distant areas.
