Jutland horse 405 stud farms were devoted to their breeding in Denmark, but since that time, population numbers have dwindled. Though numbers dropped, a 2008 study of the 716 Jutland horses in the Danish studbook at that time concluded that little risk of the Jutland becoming extinct existed due to inbreeding or low genetic diversity. The study, which also included populations of the Knabstrupper and Fredericksborg breeds, theorized that the greatest loss to genetic diversity for horses in Denmark would be through the extinction of the Jutland breed, because of its genetic distance from the other two native breeds.

Jutland border between the Danish and German realms from c. 850 to 1864. Although most of Schleswig-Holstein is geographically part of the Jutland peninsula, most German residents there would not identify themselves with Jutland or even as "Jutlanders", but rather with "North Germany" () and Schleswig-Holstein, considering themselves "Northern Germans" () and "Schleswig-Holsteiner". The medieval law Code of Jutland applied to Schleswig until 1900 when it was replaced by the Prussian Civil Code. Some rarely used clauses of the Jutlandic Code still apply north of the Eider, even some cities south of the river- all of Rendsburg and more than half
