Because the poster usually known as Extreme Conservative lives there?

ExtremeConserative (and Blairite) gave us really good posts upthread, and what I was thinking when I named Williamson was a more "cultural" conservatism that goes beyond the Trumpian Republican politics of our moment.  Williamson has some of the biggest Evangelical churches in the country (as alluded to), the population resides almost entirely in SFHs headed by married couples, is ~90% White, high income, and exhibits high levels of trust in social institutions (churches, schools, community groups, etc.)  I also like Blairite's suggestion as Baldwin, AL as a potential answer, but the historic French Catholic culture in Lower Alabama/Mobile diminishes Evangelical influence in the area a bit IMO.

Rural counties mentioned by other posters may be more Republican or "Trumpian" but they are not more "conservative."  They are poor, uneducated, have remarkedly low levels of social trust (church attendance throughout rural Appalachia is abysmal) and have a much higher proportion of single-parent or mixed households than places like Williamson or Baldwin.

Idk how accurate that GPS tracker map is.  No way Marin County, CA has higher church attendance than many counties in the MS Delta.

I can believe it.  Per capita income in Humphreys County, MS is $11k a year (and it's only the 7th-poorest in MS).  The population is overwhelmingly Black, impoverished and young (~33% younger than age 18).  A lot of (Black) people in the rural Delta don't even own cars and live in houses with dirt floors.

What may be happening with the data is a combination of low cell phone penetration + non-established religious communities (i.e., "living room" churches) that aren't reported as church attendance, but please don't operate under the assumption that the MS Delta (and other parts of the rural South) are exceptionnally "churchy"

blacks have the highest rate of church attendance among all races.

Usually yes, but the Black population in the MS Delta is exceptionally poor and disadvantaged compared to the national Black population, even.

When you're considering edge cases, you shouldn't expect to see the rule.  You should expect to see exceptions to that rule.
