In the 1820s, Danish geographer Conrad Malte-Brun recorded as many as 33,000 inhabitants in Greater Cumania, 8,400 of whom lived in Karcag (spelled "Kardzag"). He also estimated that Little Cumania, comprising "two valleys", was home to 42,000 people, with roughly the same number of Jazyges living in the eponymous area. He records Greater Cumania's surface as being 20 Hungarian miles, which is approximately 160 square kilometers; he estimated Little Cumania and Jazygia as having approximately 320 and 150 square kilometers, respectively.
