What it’s like
The place. Dennis is a very small community in Tishomingo County, in the northeast corner of Mississippi. With so few residents, it is the kind of place where people tend to know one another and daily life moves at an unhurried pace. Winters are mild and cool rather than harsh, summers are hot, and rain and melted snow fall steadily across the year.
Work. Residents work mostly in manufacturing, in schools, hospitals and social care, in the building trades, and in shops. Across Tishomingo County, the largest workplaces include Northrop Grumman Systems, which makes space vehicle parts, the county school district, and Tempursealy, a mattress manufacturer. Unemployment across the county is lower than it was a year ago, and the county has added jobs over the past year.
Things to do. Tishomingo State Park, a protected area, and Bay Springs Lake, a reservoir, are both a short drive away and are good for time outdoors. A longer drive brings you to the Natchez Trace Trail, a long trail, and to Pharr Mounds, an archaeological site.

FEMA’s National Risk Index (December 2025) rates the risk each natural hazard poses to the people, buildings and farms in Dennis’ 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 Tishomingo County.
