What it’s like
The place. North Henderson is a small village in Mercer County, Illinois, with a population that keeps it on the quiet side. Household incomes are about level with the county's, and a typical home here costs less than many would expect elsewhere in the state. Winters are cold and snowy, with January the coldest month, while summers turn warm in July and the year brings a fair amount of rain and melted snow.
Work. Residents work mostly in schools, hospitals and social care, with others in manufacturing, shops and the building trades. Across Mercer County, some of the largest workplaces are Mercer County School District, Genesis Medical Center - Aledo and Walmart. Unemployment in the county is lower than it was a year earlier, and the county has gained jobs over the past year. Few people work from home, and the typical commute is a bit longer than a quick trip across town.
Things to do. Henderson Creek, a river, and the Alexis Opera House, a theatre, are both a short drive away. For a longer outing, Carl Sandburg State Historic Site is a museum within a longer drive, and Big River State Forest, a protected area, is also a longer drive away. Both make a fine day trip from the village.
