Kouvola, which had population growth as late as the 1980s, has suffered a loss of migration since the 1990s. Over time, the loss has only deepened, so that at the end of the 2010s Kouvola was Finland's worst migration loss area. Natural demographics have also trended downward; in 2017, more than 450 more people died in the city than new ones were born. Currently, the population of Kouvola is decreasing annually by about 800 inhabitants. The reasons for the emigration are thought to be largely due to job losses in the region.

The village of Kouvola has been inhabited since the Middle Ages, and it has belonged alternately to the churches of Hollola, Iitti and Valkeala. However, the actual development did not start until the 1870s when the Riihimäki–Saint Petersburg line was built and Kouvola became a railway junction. Kouvola railroad built Kymin mill founder Axel Wilhelm Wahren railway administration by on application, on the basis of the track engineers decided to recommend the creation of a fifth-end position in a half mile east of the variable alert Otava with acceptance on sandy soil on fabric. In the next decade, the Savonia railway was built from Kouvola to the north and the Kotka line to the south, resulting in Kouvola becoming one of the busiest railway junctions in Finland. Over time, Kouvola developed into an important pulp-producing, paper-milling and printing centre and even had a leading industrial engineering sector.

In 1918, conflict between the Red and White factions raged heavily during the Finnish Civil War. More than 200 people were killed in the area during the fighting.

As a result of the railway, Kouvola was heavily built. In 1922 it was separated from the municipality of Valkeala and gained commercial rights immediately the following year. The city of Kouvola was established in 1960. Kouvola was annexed to Viipuri Province in 1922–1945 but in 1940 and 1944, most of Viipuri County was ceded to the Soviet Union, and the remaining areas were formed into Kymi Province in 1945. Kouvola had also become an administrative center; As the capital of Kymen County, it operated from 1955 until the 1997 county reform.

In January 2009, the six municipalities of Kouvola, Kuusankoski, Elimäki, Anjalankoski, Valkeala and Jaala were consolidated, forming the new municipality of Kouvola. Kouvola has also assumed the slogan Kymijoen kaupunki (the town of Kymijoki) previously used by Anjalankoski.
