Republicans talked about the Canadian border. They skipped all sorts of details

A group of Republican lawmakersleft out all sorts ofdetails earlier this week when they held a news conference in Washington to sound the alarm about a surge in migration from Canada.

They put some big numbers on a poster and included those same bulging figures on a handoutdistributed to journalists.

They noted, correctly, that irregular border-crossings from Canada are up.

Here's what went unsaid: The sum they were touting was a kitchen-sink statistical catch-all, a throw-everything-in-there mish-mash of federal data.

Meaning that the number of irregular crossings is so small, representingsuch a minuscule fraction of the total they touted,it's the equivalent to a statistical blip.

The issue involves what the U.S. Department of Homeland Security calls "encounters" and it covers a vast array of incidents at the U.S. border.

Such incidents range from the innocuous to the serious: from someone forgetting their passportor lacking proof of a COVID-19 vaccination, to missing a work visa, to being refused entry over a criminal record, to someone trying to sneak across.

Thosefigures, then, can frustrate migration-policy analysts. They argue the catch-all number winds up being used to confuse people more than enlighten them.

"The numbers require explanationand contextualization," said Kathleen Bush-Joseph, of the Washington-based Migration Policy Institute. "Looking at encounter statistics, it requires getting into the details."

The Republicansdid not, by any means, sweat the details.

Take thefact sheet they handed out: Itcited a 1,498 per cent increase in land-border encounters since U.S. President Joe Biden took office. Never mindthat, in January 2021, landtravel was severely restricted under pandemic rules.

The grand total: 2.7 per cent

So what are the numbers at the U.S.'s northern border?

The data from U.S. Customs and Border Protection (CBP) show about 165,000 encounters along the northern U.S. border since the start of 2022.

That's the stat Republican lawmakers showed.

Then if you filter that data for people being stopped betweenofficial ports of entry, here's what you'll find: 2.7 per cent.

Ninety-seven per cent are people stopped at normal border crossings by CBP's Office of Field Operations.

To their credit, the Republicans listed the more precise, smaller numbers in a letter last week to the U.S. Homeland Security secretary, demanding details of his plan for the northern border.

The detailed data shows about 4,500 people being stopped from migrating into the U.S.from Canada,between normal checkpoints, since the start of the 2022 fiscal year.

Which, as the Republicans correctly identified, is an increase: If the current rate held, the 2023 number could end up being triple the number last year's, according to U.S. data.

Yet even that comes with an asterisk.

Ignoring the pandemic effect

The chart on the Republican poster startsin 2020, so it doesn't show the pre-pandemic level in fiscal year 2019.

Using that year as a baseline instead, there's a less dramatic trend: a 35 per cent bump over 2019, not the 300 per cent when compared to last year.

Digging down even deeper, some of that 35 per cent is due to pandemic rules: Back in 2019, travellers weren't being turned back at the U.S. border for lacking vaccine papers.

Some Republican lawmakers demanded more personnel at the Canadian border, saying they wanted more agents hired in their districts.

They decried the staffing disparity: the Mexican border has about 20 times the total number of U.S. border patrol agents as the northern border.

That is consistent with migration enforcement stats.

Comparison with Mexicanborder: there is none

The southern border with Mexico, since the start of the 2022 fiscal year, has produced about 20 times more encounters than the northern border with Canada.

But the disparity in migration runs even deeper than the fact that the Mexican border has seen 3.25 million of those so-called encounters, to Canada's 165,000.

The differences in the detailed data are more pronounced.

Again, a minute percentage of so-called encounters recorded at the Canadian border occurred between border checkpoints, 2.7 per cent.

It's the opposite along Mexico's border, where 91 per cent of so-called encounters involved Border Patrol agents,who enforcebetween checkpoints.

Republicans take aim at human trafficking across Canada-U.S. border

A group of U.S. Republicans are banding together to call attention to what they say is a surge in human trafficking from Canada into the U.S., forming what they're calling a Northern Border Security Caucus.

Despite all these differences, another U.S. immigration expert said the recent trend with Canada is worth paying attention to.

For starters, she said, there's the question of migrant safety. It's undeniable that more are crossing, even in the harsh winter months. A family of four from India, for example, froze to death trying to cross from Canada last year.

"Due to the danger of winter crossings, [it's] still a concern," said Theresa Brown, an immigration analyst at the Washington-basedBipartisan Policy Center.

The trend also raises questions for U.S. policymakers, she said.

One involves the potential impact on already-strained U.S. immigration systems, with the courts that process such claims facingmounting backlogs and years-long delays.

Analyst: Still worth examining this trend

Brown further saidthis recent trendline at the Canadian border could indicate an emerging pattern in migration: people using Canada to get to the U.S.

For example, Mexican citizens don't need a visa to travel to Canada; they do need one for the U.S. And more than 2,100 Mexicans have been stopped by U.S. Border Patrol between regular northern border checkpointssince the start of 2022.

American officials, Brown said, will want to know what's driving this whether it's new enforcement at the southern borderorother phenomena.

The bottom line on this issue?

The increase is real. The numbers are tiny. And politicians, sometimes, cherry-pick from that great big tree of data.
