In comparison, one-third (34%) of Americans believe the agreement has benefited the U.S., while 23% say that it has hurt their country. One-third (32%) say that it hasn't had any impact on the United States. Mexicans are the most evenly split on the effects of NAFTA on their country, with 29% who say that the agreement has benefited Mexico, 33% who say it has hurt the country, and an equal number (33%) who say it has not had any impact on Mexico.
