What is considered to be Northwest Ohio, with the dark-blue colored counties always included, the middle shade of blue counties being included some of the time, and the lightest colored blue counties being included the least.

Northwest Ohio, or Northwestern Ohio, consists of multiple counties in the northwestern corner of the US state of Ohio. This area borders Lake Erie, Southeast Michigan, and northeastern Indiana. Some areas are also considered the Black Swamp area. The Toledo metropolitan area is part of the region.

Northwest Ohio's population in 2000 was 1,639,144 and is declining, specifically in the northern regions (counties shaded in the darker blue and Allen County). However, southern areas, such as Marion and Morrow Counties, and the City of Findlay are growing.

Largest municipalities

The city of Toledo serves as the principal city for the region of Northwest Ohio. Most of the region's television channels and radio stations are licensed in either Toledo, Perrysburg or nearby Bowling Green. Though Toledo is an industrial city, the region is primarily agriculture with relatively small centers of commerce in various locations. In recent years, Lucas County (i.e., Toledo, Sylvania, etc.) has seen a steep decline in population since 1970, whereas neighboring Wood County (i.e., Bowling Green, Perrysburg, etc.) and Hancock County (i.e., Findlay) have experienced modest, yet steady, growth.
