Northern Kentucky

This article is about the geographical region. For the university, see Northern Kentucky University. For that school's athletic program, see Northern Kentucky Norse.

Northern Kentucky is the name often given to the northernmost (most typically the three northernmost) counties in Kentucky (Boone, Kenton, Campbell, shown in red on the map). Gallatin, Grant, Pendleton, and Bracken counties (highlighted in pink on the map) are often group with the aforementioned and are officially part of the Cincinnati Metropolitan Area, and are sometimes included in definitions of "Northern Kentucky". Historically, Trimble and Mason counties have also been included in "Northern Kentucky".

The three northernmost counties of Kentucky each has at least one major center of population: Florence in Boone County; Covington, Erlanger, and Independence in Kenton County; and Newport, Fort Thomas, and Alexandria in Campbell County. Immediately on the northern side of the Ohio River from Covington and Newport is Cincinnati, Ohio. However, the entire core region is relatively densely populated, with these cities surrounded by many smaller towns which have little other than a city limit sign between them. The periphery of Boone, Kenton, and Campbell Counties, namely the western half of Boone County, and southernmost parts of all three of the core counties, are still primarily rural in nature. The four outer counties are still primarily rural. Combined with the southeast corner of Indiana, and Southwestern Ohio, all seven counties are a part of the Greater Cincinnati area, which has a population over two million.

The area was served by ferry service across the Ohio River until the completion of the John A. Roebling Suspension Bridge (prototype of the famous Brooklyn Bridge) in 1866, whereupon land values in the areas near the river quadrupled overnight.

Beginning in the 1970s, many factors combined to create major growth. The proximity to Cincinnati, the completion of I-75, the nexus of rail service and river traffic, creation of several industrial parks, and the growth of Cincinnati/Northern Kentucky International Airport (located near Hebron in northeastern Boone County near the Kenton County line) drew many industries into the area. Its geographically central location (within 800 miles of 80% of the US population) makes it ideal for distribution centers, and those shipping all over the country.

Climate

Northern Kentucky is located within a climatic transition zone and is at the extreme northern limit of the humid subtropical climate. Evidence of both humid subtropical climate and humid continental climate can be found here, particularly noticeable by the presence of plants indicative of each climatic region; for example, the Southern magnolia, Crape-myrtle, and Needle palm from the subtropics and the Blue spruce, Maple, and Eastern Hemlock from cooler regions are successful landscape plants in and around Northern Kentucky. Some significant moderating variables for the overall climate of Northern Kentucky include: the Ohio River, the region's relatively large hills and valleys, and an urban heat influence due to the proximity of the Cincinnati/Northern Kentucky metropolitan area. The wall lizard, introduced from Italy in the 1950s, is an example of fauna in the area that lends a subtropical ambiance to the region. Northern Kentucky is considered to be within the periphery of both the Midwest and the Upland South.
