Why these metrics?
Access to affordable housing is paramount in determining where to live and thus raise a family. It is important to ensure that housing is available to people of all socio-economic levels. In Virginia Beach, this is especially important given the disbursement of jobs in the market that range from entry level to low skill to high skill.
These metrics provide a comparison of housing costs to income. As the ratio of housing costs increase as a proportion of income, a families ability to obtain other necessities declines.
