Manufacturing accounts for roughly one-fifth of all employment in the Toledo metropolitan region. Traditionally two types of manufacturing have been important to Toledo's economy—glass and automotive.
Toledo's proximity to the center of vehicle manufacturing in Detroit, Michigan, accounts for the importance of the automotive industry. Toledo supplies parts to automobile assembly plants, even though many assembly plants have moved away from Detroit in recent years. Toledo continues to be a viable supplier because of its location near the center of the nation. Leading automotive-related employers in the metropolitan area are Chrysler (Jeep vehicle assembly), General Motors (auto and truck transmissions), Cooper Engineered Products (hoses and seals), and the Dana Corporation (vehicular component parts).
