Interviews per Neighborhood

With a sufficient number of Interviews, we can investigate processes like
The efficacy of Neighborhood-Association strategies for recovery,
Social influences on the crime rate,
And other macro and multi-level processes.

Sample Size is N = ca. 7,000

(Hollow red dots are interviews outside Orleans Parish)

Interviews per Census Tract

This is more fine-grained than Neighborhoods,
and consequently, has fewer average interviews per district.

Sample Size is N = ca. 7,000

 


 

Neighborhood Associations

We are investigating the efficacy of
Neighborhood-Association strategies for recovery,

Sample Size is N = ca. 7,000


Detailed View:

Not all neighborhood associations have responded to our survey yet.

 

How many people know the name of their
Neighborhood Association?


 

Selected Findings Mapped


Note: We use the finest (smallest) "district" size we can, consistent with getting reliable data/averages per district

A Sequential View of Rebuilding*

Residential Rebuilding In Greater New Orleans, 2005-2013 from Rick Weil

*The Sequence shows:

  1. Greater New Orleans before the flooding
  2. The extent of the flooding
  3. Residential Rebuilding in Selected Census Block Groups in 2007-2010

Source of Rebuilding Data: University of New Orleans Geography Department Surveys
Source of flood layers: US Geological Survey.



Physical Characteristics:
Flooding caused Damage,
Damage created Blight, and
Damage hindered Repopulation

But where do Social Characteristics fit into the picture?

Extent of the Flooding


Source of flood layers: US Geological Survey.

 


Damage to Residences
Damage corresponds to flooded areas.


Source of housing damage layer: City of New Orleans.

 


Damage to Residences per Census Tract

Source of Damage data: City of New Orleans


 

Blight (mean quarterly rate, 2006-2010)

Source of Blight data: U.S. Department of Housing and Urban Development (HUD)
and the United States Postal Service (USPS): here

 


Reduction of Blight, 2006-2010

Map shows only census tracts that flooded substantially.
Map excludes housing developments (because the government demolished & rebuilt them),
and tracts that had less than 10% blight in 2006 (because small changes would represent large percentage changes).

Your Own Recovery
Recovery does not fully correspond to flooded areas.
What other factors play a role?
(Note! Interviews were conducted at widely different times)

"My Neighborhood Can Be Protected from Flooding"
Optimism also does not fully correspond to incidence of flooding.
What other factors play a role?


Source of interview points: LSU Post-Katrina Surveys

 


"I Have Enough to Repair or Replace Storm Damage"
Resources for Recover do not fully correspond to incidence of flooding.
Income or Wealth certainly plays a role, too.  What else matters?
