Correlation analysis is an insightful way to determine not cause-effect between complaint intensity and local characteristics, but the relationship strength between them.
The correlation coefficient is interpreted as r=1: strong relationship, r=0: no relationship
- Tenure: Renters with contract rent (r=0.5)
- Average resident Age: 35 to 64 (r=0.5) and 45 to 54 years (r= 0.38)
- Year householder moved into unit: 1990 – 2009 (r=0.4)
- Hispanic or Latino (r=0.43), Black or African American (r= 0.41), Some other race alone (r=0.39)
- Household Income 2015: Less than $10.000 (r=0.4), $10k to 20k (r=0.4), $20k to 40k per year (r=0.4)
- Poverty Status: Household Income in the past year below poverty level (r= 0.4)
- 50% of income goes for rent (r=0.4)

- Year Built: 1939 or earlier (r=0.5)
- Household units in building structure: 20 to 49 (r=0.6), more than 50 (r=0.4)
Notes to method: A Spearman correlation analysis was applied between the 2016 ACS data and Complaint Density (total complaints/total number of residential buildings per CBG). The minimum unit of analysis is at the Census Block Group scale - providing a high level of data detail; the area normally represents 1 to 3 contiguous rows of residential buildings). Population and Housing information was extracted from the best-detailed data source available: the 2016 ACS Census (with ~3.000 indicators).
Correlation results, census indicator selection criteria: correlation coef r>=0.40, with statistical significance p<0.01)
> About the NYC Department of Housing Preservation and Development (HPD) Complaint Process: In the case of a maintenance failure from the landlord, residents may require the city HPD to reinforce building or unit maintenance and intervene by the landlord. HPD sends a notification to the registered owner to advise about the problem and doesn't close the complaint. A call may also be made to the tenant to confirm whether the condition has been corrected. If there is no confirmation of correction by the tenant, an inspector may be dispatched.
Complaints about a housing condition can be filed by calling 311, using 311 online [nyc.gov/311 ]or filed through the 311 mobile app.
