While two separate Ohio state routes meet at the intersection (SR 91 and SR 261, at one point SR 18 and SR 532 also met there), the Circle can and regularly does accommodate several dozen vehicles at a time without congestion. The eight roads that meet at the Circle form a spoke design (see image, upper right) that, as they lead away from the Circle, travel in the cardinal and ordinal directions. The roads are named according to the respective directions they travel away from the Circle; these names are not preserved by the neighboring municipalities into which the eight roads run. Out-of-town drivers can often be uncomfortable with the intersection because of the lack of stop signs or traffic lights.
No alcohol could be bought or consumed in public in Tallmadge until the early 1990s, when the law was amended to allow the retail sale of alcohol in stores, but public consumption was still illegal. In 2001, the law was repealed and alcohol could be sold and consumed in restaurants, provided that alcohol not account for more than 30% of any establishment's revenue. The first restaurant to offer alcohol in Tallmadge was Delanie's on West Avenue.
Tallmadge lies within two counties. While the vast majority of the city lies in Summit County, a small portion on the east side protrudes into neighboring Portage County (although all politics and economics in the city are associated with Summit County). This phenomenon resulted from the annexation of a small portion of a neighboring township, Brimfield.
According to the United States Census Bureau, the city has a total area of 14.0 square miles (36.2 km²), of which, 14.0 square miles (36.2 km²) of it is land and 0.04 square miles (0.1 km²) of it (0.14%) is water.
There were 6,273 households out of which 32.0% had children under the age of 18 living with them, 63.0% were married couples living together, 8.9% had a female householder with no husband present, and 24.9% were non-families. 21.3% of all households were made up of individuals and 10.4% had someone living alone who was 65 years of age or older. The average household size was 2.56 and the average family size was 2.99.

Among other institutions, Kent State University and the University of Akron provide post-secondary education in the adjacent cities of Kent and Akron; the majority of college-bound students from Tallmadge High School attend one of these two schools after graduation. No colleges or universities currently exist within Tallmadge, but Case Western Reserve University began its first classes in Tallmadge in 1826 before moving to a permanent facility in nearby Hudson and its current home in Cleveland.
