I used the word “majority”, which doesn’t precluded that “some” are here legally.

If I had to quantify my suspicion of Spanish radio listeners in my city, I’d say that 90% are likely illegal immigrants.

If I was in Florida, I’d say that 10% are likely illegal immigrants.

Don’t interpret my observation of illegal immigration existing as condemnation of a group of people who migrated across vast distances and dangerous deserts in order to work hard manual labor jobs in order to better their families. If I were in their shoes, I’d do the same. But, that doesn’t make it any less illegal.

Your figure is not even an observation; it is a guess. There are paid statisticians doing this job whose data you can cite that would make your argument more compelling.

Where would I find such statistics? I don’t doubt they exist.

My figure is a direct observation having worked landscaping and construction jobs in my town along side people who are illegal and open about it. Then, interacting with the second and third generation friends in school, they weren’t listening to the Spanish radio stations.

DHS maintains official statistics of various metrics, which can be found on their website. Here's an example set: https://www.dhs.gov/publication/entryexit-overstay-report

CBP also maintains statistics: https://www.cbp.gov/newsroom/stats/sw-border-migration

In the private sector, Pew Research (a well regarded, nonpartisan institution) generates statistics using loads of studies. See, e.g., https://www.pewresearch.org/fact-tank/2019/06/12/us-unauthor...

These are all readily found using some basic Google searches.

Ok, someone could take the pew research numbers on illegal immigration by metropolitan region, and then correlate that to Spanish radio listenership in those metros based on the Nielsen tlr data. As much fun as that is, and as much as I appreciate the HN readers demand such validation, I’ll let someone else run those numbers.

So you are just pulling numbers out of thin air. You don’t know the total population of Latinos or the population of people who crossed a border without going though a port of entry or over stayed their visas.

I’m using direct observation and interaction with people in my city. Bayesian inference based upon a sizable sample size across many years? If you have a source of immigration status of Spanish radio listeners by US metropolitan area, it would be an interesting number. Someone has those numbers using more quantifiable methods than my sampling technique.
