Mexicans' views of the U.S. and President Trump both dropped in 2017 to the lowest reported rates in the past decade and a half, according to a poll released Thursday.

A Pew Research survey taken this spring found 93 percent of Mexicans have "no confidence" in the current U.S. president and only 5 percent do.

At former President Barack Obama's worst point in office, 38 percent of Mexicans said they did not have confidence and 54 percent said they do believe in him.

Obama's predecessor, George W. Bush, fared worse than Obama, but not as poorly as Trump. Bush received a 16 percent confidence rating and 77 percent no confidence score in 2008.

Approximately two-thirds of Mexicans have an unfavorable view of their northern neighbor and 30 percent have a positive perception of the U.S. America was seen positively by the majority of Mexicans during Obama's two terms and the country's unfavorability rating never dropped lower than 27 percent.

Mexicans are increasingly less inclined to work and live in the U.S. without authorization, which coincides with Trump's tough stance on immigration and border security.

An estimated one-third would like to live in the U.S., but only around 13 percent would do so legally. That number has dropped from 20 percent in 2015 who said they would have been willing to live in the U.S. without legal documents. The decrease may be a result of the Trump administration's enhanced interior and border enforcement.

However, the number of Mexicans who believe those who move to the U.S. have a better life there increased 7 percentage points — from 48 percent in 2015 to 55 percent now. The amount who think life will become "worse" moving from Mexico to the U.S. dropped in that two-year time span from 14 percent to 10 percent.

Mexicans are also concerned about their country's economic ties with the U.S.

Trump threatened during his campaign to tear up the North American Free Trade Agreement, but has since said his administration is working with Mexico and Canada to make changes to the deal.

Although a majority of Mexicans believe the economic relationship with the U.S. is "good," that number has dropped 21 percentage points since 2009, when Obama was sworn into office.

The poll's margin of error was 4.4 percentage points. The number of Mexicans surveyed and whether respondents were registered voters or residents was not included in the survey or shared by Pew.
