Trends in Households and Possible Demand Effects on Housing in America’s Cities Peter Hayward University of California—Santa Barbara Demand 2 Supply Demand
Project Plan • Analyze possible demand changes for city housing due to the influence of changes in households • Relate preference surveys with forecasted changes of household ages and household types • Set up weighted analyses for household cohorts • Compare cohorts
Preference Surveys • American LIVES; Fannie Mae National Housing Survey; NAHB: What Home Buyers Want Survey • Express typical American homebuyer preferences • Statistical breakdown of preferences: • By household age and household type • Percent that prefers each type of housing (suburban ranch, city townhouse, city SFH, etc) • Mean and standard deviation of housing preferences
Preference Surveys (2) • Limitations: • Not regionalized • Not expanded preferences • Only sample of population • Only looking at household ages and types • Preferences are not consumption
Household Trends • U.S. Census Bureau • Projections to 2010: absolutes and percents • Household age and type • Joint Center for Housing Studies • Mobility rates • Homeownership Rates • Household age and type
Household Trends (2) • Weighted analysis • (cohort’s projected growth)*(mobility rate)*(homeownership rate) • Statistical breakdown of weighted household cohorts • Positive and negative mean • Standard deviation • Cohorts with discernable effects on demand • Limitations • Outside considerations (government intervention, disease, etc.) • Housing constructions mirror household growth
Relating Household Trends and Preferences • Four Outcomes: • Growing Household Cohort (Above Positive Mean) + Higher than Average Preference for City Housing = Higher Demand • Growing Household Cohort (Above Positive Mean) + Lower than Average Preference for City Housing = Lower Demand • Shrinking Household Cohort (Below Negative Mean) + Higher than Average Preference for City Housing = Lower Demand • Shrinking Household Cohort (Below Negative Mean) + Lower than Average Preference for City Housing = Higher Demand
Further Analysis and Conclusions • Further analysis • Greater than 1 standard deviation above & below means • Greater than 2 standard deviations above & below means • Conclusions and impacts • Not exact demand statistics but general idea of future changes • Understanding of future social landscape of America’s cities • May aid contractors, developers, local & regional governments • Replication of methodology
