This poll, fielded August 2011, and the third of four, is part of a continuing series of monthly surveys that solicit public opinion on a range of political and social issues. This poll surveyed respondents who, in a previous poll, had identified themselves as family members or friends of individuals killed in the terrorist attacks on September 11, 2001. Details were sought regarding each respondent's relationship to a victim, whether the person was a first responder, and whether the person died at the Pentagon, the World Trade Center, or aboard the flight that crashed in Pennsylvania. Respondents were asked whether they had formed any close friendships with family members or friends of other victims, whether first responders and families of victims had been fairly compensated, and whether they felt their loved one had been properly memorialized. Surveyors also inquired on general aspects of respondents' lives since the attacks, including whether they had recovered financially and emotionally, whether they had suffered from a diagnosed mental health issue, and whether the events had caused them to change jobs or move their place of residence. Furthermore, respondents were asked to gauge the likelihood of another attack within the upcoming months, and whether they believed security initiatives implemented following the terrorist attacks had enhanced public safety at airports, bridges, tunnels, subways, and nuclear power plants. Opinions were also collected regarding United States military campaigns in Iraq and Afghanistan. Additional questions solicited views on Mayor Rudolph Giuliani's handling of the attack on the World Trade Center, on the planned redevelopment of the site at Ground Zero, and on the proposed mosque and Islamic community center two blocks from Ground Zero. Demographic information includes sex, age, race, marital status, education level, household income, religious preference, and political party affiliation.

In order to protect respondent anonymity and prevent disclosure risk, ICPSR created the variable ICPSR_ST by deriving data from the original state code (STCD) variable. Geographic data was grouped into two categories: "New York and surrounding states" and "All other states".

854 respondents with relationships to victims of the September 11th terrorist attacks were identified in previous CBS News/New York Times Polls conducted since late 2010. A variation of random-digit dialing (RDD) using primary sampling units (PSUs) was employed, consisting of blocks of 100 telephone numbers identical through the eighth digit and stratified by geographic region, area code, and size of place. Phone numbers were dialed from RDD samples of both standard land-lines and cell phones. Within households, respondents were selected using a method developed by Leslie Kish and modified by Charles Backstrom and Gerald Hursh (see Backstrom and Hursh, SURVEY RESEARCH. Evanston, IL: Northwestern University Press, 1963).


Persons aged 18 years or older living in households with telephones within the United States, that were previously surveyed and had some relation to an individual killed in the September 11, 2001 terrorist attacks.

2013-01-08 ICPSR data undergo a confidentiality review and are altered when necessary to limit the risk of disclosure. ICPSR also routinely creates ready-to-go data files along with setups in the major statistical software formats as well as standard codebooks to accompany the data. In addition to these procedures, ICPSR performed the following processing steps for this data collection:

  • Checked for undocumented or out-of-range codes.

The data contain weight variables that should be used in analyzing the data. According to the CBS News Web site, the data were weighted to match United States Census Bureau breakdowns on age, sex, race, education, and region of the country. The data were also adjusted for the fact that people who share a telephone with others have less chance to be contacted than people who live alone and have their own telephones, and that households with more than one telephone number have more chances to be called than households with only one telephone number.
