Abstract
Job related houses are generally larger in scale than private rental houses. Within the rental housing market, job related housing would share higher ratio as unit size criterion is raised. Rent ofjob related houses is generally lower than that of private rental houses. Those who live in job related houses have large families and earn high income compared with those who live in private rental houses. And dwellers of job related houses, which are comparatively large in scale, tend to move into owned houses not into private rental houses when they change houses. Therefore the market of private rental housing has little relation to that of job related housing.
