National Exit Poll for the 2006 Mexican Presidential Election (ICPSR 24609)
Principal Investigator(s): Moreno, Alejandro, Reforma newspaper-Mexico City, Mexico; Mancillas, Maria Antonia, El Norte newspaper-Monterrey, Mexico; Guitierrez, Roberto, Mural newspaper-Guadalajara, Mexico
This study was conducted by the Reforma newspaper for the coverage of the 2006 Mexican Presidential election. Respondents were asked how they voted for President, Senator, and Federal Deputy (Lower House of Congress). They were also asked about their interest in the campaigns, their opinion of all five presidential candidates, reasons for supporting their preferred candidate, and when they decided his/her vote choice. Respondents were queried on their approval of President Vincente Fox and asked to provide economic retrospective evaluations on both the personal and national level. Demographic variables include sex, age, education level, occupation, household income, religious denomination, frequency of church attendance, membership to labor unions, party identification, left-right self-placement, voter preference in the 2000 presidential and in the 2003 mid-term legislative elections, and whether they are beneficiaries of social programs against poverty.

Scope of Study
Smallest Geographic Unit: voting precinct
Date of Collection:
Universe: Voters in Mexico who turned out on Election Day, July 2, 2006.
Data Types: survey data
Data Collection Notes:
The dataset contains a weight variable (V32) based on the election's official results.
ICPSR created a unique sequential record identifier variable named CASEID.
Study Design: A total of 5,803 respondents were selected in a systematic manner throughout the day, using 3 different schedules as to allow for data transmission. Interviews were conducted from the moment ballot places opened (at 8:00 am) and until they closed (6:00 pm in the most western states, 8:00 pm in most of the country). Interviews were conducted face-to-face as voters left the precinct where they cast their vote. A filter question was asked to make sure that the respondent had effectively voted. Poll results were transmitted by phone to three centers of information gathering based in Mexico City, Guadalajara, and Monterrey. A total of 145 interviewers and 44 supervisors participated in conducting the exit poll.
Sample: The exit poll used a multi-stage probability sample of precincts previously stratified by urban-rural criteria. A total of 5,803 respondents were selected in a systematic manner throughout the day, using 3 different schedules as to allow for data transmission.
Weight: The dataset includes a weight variable (V32) based on the official results for each presidential candidate.
Mode of Data Collection: face-to-face interview
Response Rates: The response rate was 66 percent.
Extent of Processing: 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:
