Under Obama, 205,000 Mexican nationals were deported during the first 11 months of 2016.

During the election, Trump vowed to target criminals for deportation and warned that they were 'going out fast.'

In an interview with CBS's 60 Minutes just days after he won the presidential election in 2016, Trump vowed to 'immediately' deport two to three million illegal immigrants with criminal records.

Trump has also vowed to build a wall along the Mexican border.

And in September, the president decided to end the Deferred Action for Childhood Arrivals program (DACA).

DACA is an Obama-era initiative that grants work permits to more than 800,000 undocumented immigrants who were brought to the country by family members as children.

A report from the US Immigration and Customs Enforcement (ICE) showed that through early October removals of Mexican nationals were down,.

But administrative arrests of all immigrants were up 30 per cent in fiscal year 2017.

'For Mexicans who enter illegally, effective tools like expedited removal have led to increased deterrence, which has impacted entry levels,' Tyler Q Houlton, acting press secretary for the Department of Homeland Security, said in an email to Bloomberg.

Trump's deportation numbers were monitored throughout the year.

In January, federal immigration officials deported 9,913 criminals. After a slight uptick under Trump, expulsions sank to 9,600 criminals in June.

Mostly deportations have remained lower than in past years under the Obama administration.

From January to June, ICE deported 61,370 criminals, down from 70,603 during the same period last year.

Analysts said earlier this year that Trump is unlikely to hit his target deportation numbers during his four-year term.
