Why Thunder Mountain has a page
Thunder Mountain is on ExpatAlmanac because the Census Bureau's 2020–2024 American Community Survey puts at least 20 % of its residents at 65 or older, even at the low end of the survey's 90 % margin, with at least 500 residents aged 65 or older. That share is shown as a Census figure; it ranks nothing and says nothing about why anyone lives there.
