What it’s like
The place. Decker is a community in Sanilac County, in the part of Michigan known as the Thumb, where the land reaches toward Lake Huron. Winters are cold and snowy, with snow piling up across the season, and the wet months bring a steady amount of rain and melting snow. Summers are warm enough for outdoor life, and many residents of the county live in homes they own themselves.
Work. Across Sanilac County, many people work in manufacturing, in schools, hospitals and care services, in shops, and in the building trades. Jobs in the county were slightly fewer last year than the year before, while unemployment has eased over the past year. Most adults here do not hold a four-year degree, and few people work from home.
