Corinthia is the third most populated prefecture on the Peloponnese peninsula and the largest in the periphery since the 1980s when it surpassed the neighboring Arcadia's population. Currently (2001 census) the population stands at 144,527 inhabitants, while the 1991 figures showed a population of 132,139.
The Corinth Canal, carrying ship traffic between the Ionian and the Aegean seas, is about 4 km east of Corinth, cutting through the Isthmus of Corinth. The prefecture is increasingly seen as part of the wider metropolitan area of Athens, with municipalities, such as Agioi Theodoroi in the easternmost part of Corinthia, being considered suburbs of Athens.
The area around Corinth and the western Saronic including the southeastern part are made up of fault lines including the Corinth Fault, the Poseidon Fault and a fault running from Perahcora to Agioi Theodoroi. More faults are near Kiras Vrysi and Sofiko.

The highway was first paved in the 19th to the 20th century. The mid to late-20th century saw the population shifting from agriculture to other jobs as people moved to larger towns and cities as well as other parts of the world. In the 1960s, a superhighway was constructed to handle the increasing traffic between Corinth and Athens and allow higher speed limits (60 km/h to 80 km/h). This highway consists of the GR-8A, partly E65 and E94 and is tolled. The section from the old Corinth interchange eastward in Korinthia was opened in 1962 and the section west of Korinthia was added in 1969. The new highway had a significant effect on the prefecture's industry, as it lowered the cost of transportation of goods between Korinthia and the Athens metropolitan area.
In late 2006, the prefect of Corinthia announced the construction of a new dam located 5 to 7 km south of Kiato and Sicyon, near Stimanika, over the Elissos River. It will become the second largest body of water (lakes, reservoirs) in the prefecture and also the first prefecture in the Peloponnese peninsula to built a reservoir. The dam will be designed to withstand earthquakes and natural disasters including flooding.
On Tuesday July 17, 2007, a forest fire struck the area around the historic Acrocorinth and its castle. It started on a slope near Acrocorinth and the fires spread quickly enough to burn a large number of Greek Fir, pine and cypress trees in the surrounding area and reach the new GR-7 (E65) superhighway, causing traffic to be rerouted. It took a significant number of firefighters, fire trucks, two helicopters and a few planes to contain and stop the blaze from spreading. The fire was finally put out the next day. On July 19 however, two more fires started near Chiliomodi and Mapsos. They started in the late afternoon hours and burnt several forests and groves during the night.
The main sources of income are goods and services, manufacturing, tourism and agriculture.
Famous attractions include the Ancient Corinth and its acropolis, Acrocorinth, thermal springs of Loutraki, the Corinth Canal, Nemea and the Heraion of Perachora.
