Washington, DC - Public opinion surveys conducted in the United States and Mexico show that people on either side of our border have vastly different positions on the relations between our two countries.
On trade, Mexicans overwhelmingly support NAFTA while Americans narrowly support the trade deal. On building a wall, Mexicans clearly reject the idea while many Americans – particularly Republicans – support building a wall along our southern border. In fact, many Americans are pro-walls generally with 47% of American Republicans in favor of building a wall along the entire U.S.-Canadian border.
People in the two countries also differ on America’s responsibility for current events in Mexico. Most Americans feel that we are at least somewhat responsible for tensions between our governments and illegal immigration. However, most Americans do not believe that the U.S. is responsible for corruption or cartel violence in Mexico. Interestingly, a minority of Mexicans hold the U.S. responsible for illegal immigration into the U.S. but a majority feel that we are responsible for the epidemic of violence in Mexico.
About the Study
These are findings from an Ipsos poll conducted June 26-28, 2018. For the survey, a sample of 1,005 adults age 18+ from the continental U.S., Alaska and Hawaii were interviewed online in English. The sample includes 325 Democrats, 339 Republicans, and 215 Independents. A parallel study was conducted in Mexico at the same time and included a sample of 843 Mexican adults.
The sample for this study was randomly drawn from Ipsos’s online panel (see link below for more info on “Access Panels and Recruitment”), partner online panel sources, and “river” sampling (see link below for more info on the Ipsos “Ampario Overview” sample method) and does not rely on a population frame in the traditional sense. Ipsos uses fixed sample targets, unique to each study, in drawing sample. After a sample has been obtained from the Ipsos panel, Ipsos calibrates respondent characteristics to be representative of the U.S. Population using standard procedures such as raking-ratio adjustments. The source of these population targets is U.S. Census 2016 American Community Survey data. The sample drawn for this study reflects fixed sample targets on demographics. Post-hoc weights were made to the population characteristics on gender, age, race/ethnicity, region, and education.
Statistical margins of error are not applicable to online nonprobability sampling polls. All sample surveys and polls may be subject to other sources of error, including, but not limited to coverage error and measurement error. Where figures do not sum to 100, this is due to the effects of rounding. The precision of Ipsos online polls is measured using a credibility interval. In this case, the poll has a credibility interval of plus or minus 3.5 percentage points for all respondents. Ipsos calculates a design effect (DEFF) for each study based on the variation of the weights, following the formula of Kish (1965). This study had a credibility interval adjusted for design effect of the following (n=1,005, DEFF=1.5, adjusted Confidence Interval=5.0).
The poll also has a credibility interval plus or minus 6.2 percentage points for Democrats, 6.1 percentage points for Republicans, 7.6 percentage points for Independents, and 3.8 percentage points for the Mexican sample.
