By the numbers, the Big 5 townships remained the same: Algonquin, Grafton, McHenry, Nunda and Dorr.
Greenwood Township maintains the sixth most populous township with 5-digit population.
Grafton Township saw the most growth in 10 years of 6.23%, which most attributed to the Village of Huntley’s 18.28% growth within McHenry County from 2010 to 2020.
In case you missed it (ICYMI), here is the link to McHenry County’s statement on the Census 2020 final population count, issued early Friday, August 13, afternoon.
Huntley property tax rate is markedly lower than most of McHenry County.
This is attributable to Huntley Unit District 158 spending per pupil being markedly lower than most school districts in McHenry County.
For one example, over the past decade and a half, Woodstock CUSD 200 has spent around 30% more per pupil than Huntley D 158.
Higher property tax rates and extraordinary public debt has prevented any contributory (non-TIF) development in Woodstock, while Huntley has enjoyed continued growth.
I can personally verify that Richmond, Hebron and Greenwood townships have seen hundreds of Section 8 people from Chitown and Rockford slums.
Who’s giving out the vouchers and targeting white areas?
‘Roo, you are correct. But the situation is worst in Dorr Township.
