The age of housing falls into the era in which tract housing become popular with a boom in housing in the 1960s and 1970s. There is a high turnover rate for renters within the area, while homeowners have stayed put throughout the years. Introduction Housing stock is a relatively stable tool for analyzing conditions in areas as small as census tracts to larger regions such as cities and counties. What makes housing stock so reliable in measuring change in an area is the fact that a housing unit is a permanent structure. Housing data is far more reliable than population data due to the fact that housing stock in an area is not likely to experience as drastic of change as population.
Units are permanent and can be physically counted in many different forms, unlike people.
Population can be identified by social security numbers and drivers licenses, but not every person living in the United States has this form of identification. Physical addresses, tax assessors data, and parcel numbers may account for housing units. Two communities in the Southern California region are going to be compared in this report. Montclair and Pomona are similar areas, which once had similar problems. Montclair, with the help of the city, was able to clean up their neighborhoods bringing desirable communities back to the city.
