About 120,000 people live in Hunterdon County and they pay the highest property taxes in the United States with a ridiculously high average of $8,000 per home about triple the national average.

Those are great revenues for the United States. Good compilation!

Great summary, Joe.

I am shocked that Douglas County, Colorado is on this list. There are a couple of high-end communities there, but other than that.

Sam, Douglas County surprised me too but many people from NY have been moving to Colorado over the last 20 years.
