1. Gross rent is defined as contract rent plus the estimated average monthly cost of utilities (electricity, gas, water, and sewer) and fuel (oil, coal, kerosene, wood, etc.). Because some rentals include utilities and others don't, gross rent is a way of normalizing the variability.

2. Real dollars are calculated using the CPI-U less shelter series.

3. The rental vacancy rate is computed by dividing the number of vacant units for rent by the sum of the renter-occupied units, vacant units that are for rent, and vacant units that have been rented but not yet occupied.
