Obama's personal numbers have also been on the rise. In 2011, 38 percent of Mexicans were confident in his handling of world affairs; that's now at 49 percent. But Mexicans are divided on whether the U.S. is having a good or bad impact on their country's economy, even though 70 percent consider deep economic ties with the U.S. a good thing.
Most Mexicans (61 percent) wouldn't move to the U.S. if they could, but about a third (35 percent) would. (Last year, more Mexicans left the U.S. than entered it for the first time.) One in four know someone who has been deported from the U.S. or detained for immigration reasons.
Obama's three-day trip is meant to focus on trade and security, but immigration will inevitably come up.
