Why did fewer Mexicans decide to migrate to the USA in February 2017?

It's estimated that tourism from Mexico to America will be 7% less valuable in 2017, causing a reduction of $1.1 bn. The 2018 figure is set to be even lower, a drop of $1.6 bn. Those figures come from research firm Tourism Economics. Rewind, and it's apparent that the increase in anti-Mexican sentiment started during the Trump election campaign, when he frequently spoke of Mexicans in disparaging terms.

In Los Angeles, hate crimes had been dropping for 7 years to 2015 - but there was then a surge which was specifically anti-Mexican with phrases such as 'wetback' featuring,and three-quarters of those verbal attacks accompanied by physical violence. It was when Trump started to speak openly against Mexicans that his poll ratings against fellow Republican candidates increased. (Data from LA County Commission on Human Relations: Hate Crime Report, September 2016.)

"They're bringing drugs. They're bringing crimes. They're rapists." Those are just some of the words Trump used in his campaign. And his supporters have bought into and copied that bluntly racist hatespeech. With that tone set by the man who became President, is it any wonder that fewer Mexicans are willing to visit north of the border, even for a holiday?
