Fewer Mexicans Drive Changes In US Immigrant Population

So, according to this article: Fewer Mexicans drive changes in US immigrant population - https://www.yahoo.com/news/fewer-mexicans-drive-changes-us-immigrant-population-180403431.html where has the lessening of illegal Mexicans in this country produced a "profound" impact in parts of the country? Especially if the ratio has been replaced or populated by another source of illegal immigration?

Other than "sanctuary cities" a more profound line of inquiry is why illegals pick certain states and cities. I know that Massachusetts has the most liberal social welfare in the US. What is driving illegals to certain places? It still costs the US tax payer billions of dollars in misappropriated funds and other funding to shore up programs devoted to our citizenry.
