Geography 372 Final Presentation

  1. 1. Examining Urban Decay in Philadelphia Mac Ferrick, Paige Geist, Will Dorfman GEOG372
  2. 2. Defined as the process of a city falling into economic and social despair. What is urban decay?
  3. 3. ● Growth of the suburbs after World War II ● Movement of jobs outside of the city ● Deindustrialization ● White Flight/Redlining ● War on Drugs and Subsequent Crime Main causes of decay in the US
  4. 4. ● Land area: 135 square miles ● Population: 1,553,165 ● Average home value: $147,569 ● Median annual income: $37,016 ● Poverty Rate: 26.2% Philadelphia County Key Figures Source: US Census Bureau American Fact Finder (2013); Select Greater Philadelphia (2010)
  5. 5. ● Philadelphia defines an area to be experiencing urban decay as meet at least one of the following criteria: o Unsafe, unsanitary and inadequate conditions; economically or socially undesirable land use; and faulty street and lot layout ● Urban renewal projects indicate the presence of urban decay Urban Decay in Philadelphia
  6. 6. ● Urban renewal based on federal and state laws ● Decision Makers: o Philadelphia Redevelopment Authority o Philadelphia City Planning Commission o Philadelphia City Council & Mayor o United States Department of Housing and Urban Development (HUD) ● Determine areas for redevelopment, prepare plans, and select developers Redevelopment Process
  7. 7. ● Neighborhood Stabilization Program (NSP) o Purpose is to turn over vacant, foreclosed properties into owner-occupied dwellings o Determined based on historical foreclosure data, indications of predatory lending, and the impact of vacancies on surrounding home values ● Received $16.8 million in funding from HUD Urban Renewal Programs
  8. 8. ● Determine the underlying cause of socioeconomic challenges in Philadelphia County ● Determine if current redevelopment projects are targeting the correct areas Research Purpose
  9. 9. ● What is the correlation between home value and percent vacancies? ● What is the correlation between vacancies and homicides? ● Is urban decay widespread or is it concentrated in certain neighborhoods? Key Questions
  10. 10. ● Homicides ● Home vacancy percentage per census tract ● Median Household Income ● Poverty Factors Considered
  11. 11. ● Georeferencing census tracts ● “Join” data (percent vacant and median home value) to census tract file ● “Display XY Values” for homicides ● Perform a Hot Spot Analysis to present homicide data ● Overlay areas for urban renewal Methodology
  12. 12. Total number of homicides (2010): 403
  13. 13. ● Homicide hotspots in North Philadelphia and section of Southwest Philadelphia ● Coldspots in Center City, Northeast Philadelphia, and Northwest Philadelphia ● Little correlation between hotspots and urban renewal areas Findings
  14. 14. ● Vacancies are concentrated in North Philadelphia and portions of West Philadelphia ● Fewest vacancies are found in Northeast Philadelphia ● Outlier in Northeast Philadelphia ● Stronger correlation between vacancy percentage and urban renewal areas Findings
  15. 15. ● Highest home values concentrated in Center City and Northwest Philadelphia ● Lowest home values are found in North Philadelphia and West Philadelphia ● Little correlation between home value and urban renewal Findings
  16. 16. ● Poverty concentrated in North Philadelphia and West Philadelphia ● Somewhat strong correlation between poverty and urban renewal areas ● Strong correlation between homicide hotspot and poverty, especially in North Philadelphia Findings
  17. 17. ● Access to data ● Various outliers ● Presence of universities (UPenn, Drexel) ● Measurement criteria into the effectiveness of urban renewal programs Limitations
  18. 18. ● Urban renewal project are partially targeting the right areas ● There are areas that are both within and outside of urban renewal zones that are still suffering the consequences of urban decay ● Based on our findings, the areas marked for urban renewal need to be reexamined to take into account factors other than the criteria determined by the city Conclusions
  19. 19. ● Look at correlation between decay and other crimes, especially drug-related crimes ● Look at the lasting impact of redlining using historical data ● Conduct a longitudinal study to see how decay has evolved over time Possible Further Analysis
