The Associated Press-NORC Center for Public Affairs Research survey on resilience after Superstorm Sandy was conducted from July 14 through September 9 by NORC at the University of Chicago. The survey was funded by the Rockefeller Foundation.

It is based on an address-based sample of 12 New York and New Jersey neighborhoods and used online, telephone, and in-person interviews. The sample included 1,009 adults age 18 or older from the selected neighborhoods, including 300 respondents who took the survey online, 316 who responded by telephone, and 393 people who participated in in-person interviews. Surveys were offered in both English and Spanish.

The 12 neighborhoods were selected based on recovery status and socioeconomic status. The focus areas included all or parts of Hoboken, Monmouth Beach, Jersey City, Long Branch, and Point Pleasant/Point Pleasant Beach, New Jersey; and Long Beach, Islip, Babylon, Gravesend, Manhattan's Lower East Side, Midland Beach/New Dorp Beach, and Breezy Point/Belle Harbor/Rockaway Park in New York.

As is done routinely in surveys, results were weighted or adjusted to ensure responses reflected the 12 neighborhood populations in terms of age, sex, race and education.

The overall margin of sampling error was plus or minus 4.3 percentage points. This means that no more than 1 time in 20 should chance variations in the sample cause the results to vary by more than plus or minus 4.3 percentage points from the answers that would be obtained if all adults in the 12 neighborhoods were surveyed. The margin of sampling error is larger for subgroups.

Wording, order of questions, and other factors can lead to potential errors in the survey.
