The 2008-2009 ANES Panel Study is a telephone-recruited Internet panel with two cohorts recruited using nearly identical methods. The first cohort was recruited in late 2007 using random-digit-dialing (RDD) methods common to telephone surveys. Prospective respondents were offered $10 per month to complete surveys on the Internet each month for 21 months, from January 2008 through September 2009. Those without a computer and Internet service were offered a free web appliance, MSN TV 2, and free Internet service for the duration of the study. The second cohort was recruited the same way in the summer of 2008 and asked to join the panel beginning in September 2008. The recruitment interview was conducted by telephone in nearly all cases. A small number of respondents completed the recruitment survey on the Internet after failing to complete a telephone interview. Before the first monthly survey, most respondents also completed an online profile survey consisting primarily of demographic questions.

To minimize panel attrition and conditioning effects, only 7 of the 21 monthly surveys are about politics. Other surveys are about a variety of non-political topics. The panelists answered political questions prepared by ANES in January, February, June, September, October, and November 2008. With certainty, the panel answered more political questions in May 2009.

Note that the 2008-2009 ANES Panel Study is entirely separate from the 2008 ANES Time Series study, which was conducted using the traditional ANES method of face-to-face interviews before and after the 2008 election. Although there are a few questions common to both studies, the samples and methods are different. For further details, see the User Guide. Complete documentation is available on the ANES Web site.

Variable W11Q3 contains an unknown code.

The data in this collection came from the American National Election Study (ANES) Web site.

Documentation for this data collection came from the American National Election Study (ANES) Web site. The codebook was generated by ICPSR.

Character variables which contained an unlabeled value were labeled BLANK.

Question text for variables W11LB8, W11LB4, W11LB5 was not added due to inconsistencies in the user guide and variable labels.

Produced by a collaboration between the University of Michigan and Stanford University.

Original variable order was modified so that CASEID was first.

For detailed sampling and recruitment procedures, see the User Guide.

The Panel Study is designed to represent the population of United States citizens aged 18 years and older as of November 4, 2008 (Election Day). Individuals who, at the time of recruitment, were United States citizens, born on or before November 4, 1990, and residing in a United States household (all 50 states and the District of Columbia, but excluding areas without electoral votes) with a landline telephone.

The minimum response rate (AAPOR RR1) at the panel recruitment stage was 26 percent. The estimated response rate (AAPOR RR3, based on observed eligibility among known cases) at the recruitment stage was 42 percent. The minimum and estimated response rates for the 2008 ANES waves were as follows: Jan: 18 percent RR1, 29 percent RR3; Feb: 17 percent RR1, 26 percent RR3; Jun: 16 percent RR1, 25 percent RR3; Sep: 16 percent RR1, 26 percent RR3; Oct: 16 percent RR1, 26 percent RR3; Nov: 17 percent RR1, 27 percent RR3.

2011-04-28 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:

  • Created online analysis version with question text.
  • Checked for undocumented or out-of-range codes.

For detailed information on the weights used in this study, see Section 8 in the User Guide.
