Rationale

The nation is going through a tumultuous time in history, with the economy and immigration at a fever pitch. Right now, the government is shut down, and the economy has fluctuated throughout 2025. However, immigration has swelled with President Donald Trumps’ enforcement of undocumented Americans and their families. In Tennessee, this issue peaked when ICE partnered with the Tennessee Highway Patrol for traffic stops in south Nashville. Hundreds of people were arrested, and they were sent to detention facilities in New Orleans, Louisisana.

This scene has happened elsewhere across the country, these policy changes have led to protests, and it’s even affected the workforce.

The Associated Press has tracked these stories.

Hypothesis

Because of the tipping point of immigration in this country, I hypothesize that immigration and ICE will outweigh the coverage of the economy, even though these issues can be intrinsically linked. Undocumented people make up a bedrock of the economy in agriculture and other sectors.

Variables & method

An analysis of nearly 75,000 AP stories came into play. I wanted to know though how many stories the Associated Press had on the economy and immigration. That is where first-level agenda setting theory came into the picture. I used coding in R to delineate how many of those stories involved those issues. I looked at 42 weeks out of the year, which is through the end of September.

Results and discussion

The comparison from the first-level agenda theory showed that dozens of stories appeared every week about both the economy and immigration, teeter tottering like on a see-saw.

That was until week 24, when immigration stories went off like a rocket launcher. That is where several top news issues happened:

This made for an incredibly busy news week. The stories slowly started trending down from the spike, and the issue of the economy never spiked as high as it did for issues with immigration.

Because of the nature of the news cycle, it seems the hypothesis was found to be accurate.
