Truth on the US Southern Border

A decade of immigration trends, visualized and explained without the rhetoric.

This chart tracks Southwest Land Border Encounters month-by-month, overlaying the exact moments policy changes impacted the flow of migration.

Politics is about timing. The current administration claims the “historic low” border numbers of early 2025 as a victory. A “Data Is Truth” audit reveals the reality: The border wasn’t secured on Inauguration Day 2025; it was secured in the summer of 2024.

The Surge (2017–2023)

The surge actually started in 2019 during Trump’s first term. There was a dip in 2020 due to COVID. Biden’s hesitation then allowed the surge to persist for two years, but was due to a complex set of factors:

• Legislative Strategy: The administration delayed taking unilateral executive action for months, pinning their hopes on a bipartisan Senate deal that ultimately failed to pass.
• Ideological: They prioritized addressing “root causes” and reversing Trump-era policies rather than utilizing immediate deterrence or strict enforcement.
• Political: There was a reluctance to alienate the progressive base, who strongly opposed harsh border measures.
• Logistical: They lacked the diplomatic agreements necessary to deport the specific surge of migrants coming from countries like Venezuela and Cuba.

The Solution (June — Dec 2024)

Following a crisis peak in Dec 2023, encounters collapsed by 80% before the 2024 election. The Cause: The drop correlates perfectly with Biden’s June 2024 “Asylum Ban” and aggressive Mexican enforcement.

There was a relatively small spike in late 2024 due to: The “Closing Door” Panic: As polls favored a Trump victory, smugglers marketed a “now or never” urgency, convincing migrants to cross before the administration changed and the border “sealed shut.” Venezuelan Unrest: A stolen election in Venezuela (August 2024) triggered a fresh wave of refugees fleeing political crackdowns, hitting the border right as the US election cycle peaked.

The Big Lie (Jan 2025)

Trump inherited a border already at 4-year lows. The Reality: While the “Trump Effect” (fear of enforcement) likely shaved off the final percentage points, claiming credit for the massive drop from 250k to 30k is a lie.
