During his marathon morning press conference today, Mexican President Andrés Manuel López Obrador shared Customs and Border Protection’s (CBP) preliminary U.S.-Mexico Border migration statistics for the first 17 days of September. He showed this slide about 2 hours and 11 minutes into a video embedded on the Presidency’s page.

The graphic shows a total of 142,000 migrant encounters over those 17 days. It combines migrants who have entered Border Patrol custody plus those who came to official land-border ports of entry, but doesn’t distinguish between them.

In all of July, the last full month that CBP has reported, this number was 183,503.

If September’s pace continues for all 30 days, by the end of the month CBP would report 250,654 migrant encounters. Only December 2022 (252,325) has exceeded that number.

The most Venezuelan migrants in a single month was 33,804 in September 2022. September 2023, with 25,577 people in 17 days, may exceed that.
