Acting Homeland Security Secretary Kevin McAleenan on Monday broke down how the immigration crisis is rapidly changing the demographics of Central American countries.

The DHS chief — delivering a speech at the 49th Washington Conference of the Americas — said over 1% of the entire Guatemalan and Honduran populations emigrated to the U.S. since September 2018. The comments were first flagged by the Washington Examiner.

“The current migration flows, especially of vulnerable families and children, from Central America through Mexico, to remote areas all along the U.S. border, represent both a security and humanitarian crisis. The situation is not sustainable,” McAleenan said Monday.

If the DHS chief’s numbers are accurate, then roughly 250,000 Hondurans and Guatemalans have left for the U.S. in the past eight months. The population size is nearly equivalent to that of Buffalo, New York.

Customs and Border Patrol (CBP) announced in April that 418,000 nationwide apprehensions have occurred this fiscal year to date. A total of 404,142 nationwide apprehensions took place last fiscal year, a CBP spokesperson told The Daily Caller News Foundation. The numbers indicate how many more migrants are attempting to enter the country.

A large bulk of these migrants are family units and unaccompanied minors from the Northern Triangle of Central America — Guatemala, Honduras and El Salvador.

While so many of them have already emigrated, many of the remaining citizens have still expressed a strong preference to move. A survey by a local Guatemalan newspaper found 39% of its citizens intend to leave the country. Of those who said they wanted to go, 85% chose the U.S. as the country they hoped to land in.

While immigration reform has continued to be a priority for the Trump administration, polling suggests many more Democrats are agreeing the situation at the border is, in fact, a crisis. 35% of self-identified Democrats said they believed the U.S.-Mexico border is experiencing a crisis, according to a Washington Post-ABC News poll released in April. The results were a more than three-fold rise from the last time the question was asked in January.
