This doesn't actually allow any sort of answer to be discerned except "probably someone in Texas or California", and I don't find that a very satisfying answer to the question "who?".
All that is really presented is rates of missing insurance as percentage of total population of state/city. The different sorting options show noise, so aren't really useful. Average income, education level and life expectancy would probably be better quantities than %non-citizens, the latter best serving as some sort of noisy proxy for other measures (unless some sort of racist idea where non-citizens are a homogeneous blob of "other" that is totally distinct to people who have gained citizenship).
