What it’s like
The place. Algonquin is a village in McHenry County, with a population that has grown past what many villages its kind reach. Households here earn more than across the county as a whole, and fewer people live below the poverty line than in many places. Nearly all homes are lived in by their owners, and a large part of adults hold a four-year degree. Winters are cold and snowy, with January the coldest month, and summers are warm, with July the warmest. Rain and melted snow add up to a fair amount over the year.
Work. Residents work mostly in schools, hospitals and social care, in professional and business services, in manufacturing, and in shops. Among the largest workplaces in Algonquin are the school district, Walmart and Target. A good number of people work from home, and the typical commute is a fairly long one. Unemployment has risen a little over the past year, while across McHenry County the number of jobs has grown slightly.
Things to do. Close by, Santa's Village Amusement & Water Park is a short drive away, and so is Hampshire Forest Preserve, a protected area for walking and being outdoors. Farther afield, Geneva Lake is a longer drive away and suits a day by the water. The Chicago Botanic Garden is also a longer drive away, for those who like to wander through planted gardens.

FEMA’s National Risk Index (December 2025) rates the risk each natural hazard poses to the people, buildings and farms in Algonquin’s census tracts, against the rest of the country; all of them together, relatively moderate. It is meant for planning, not a substitute for a local risk assessment or a flood map: FEMA’s index.
From the U.S. Census Bureau’s 2020 census and its American Community Survey (2020–2024 five-year estimates), and the Bureau of Labor Statistics. A survey, so each figure has a margin of error, and figures it is not sure of are left out. More on McHenry County and the Chicago-Naperville-Elgin, IL-IN-WI metro.
