The file [Typology of concord - Leufkens (2020)] contains raw typological data acquired by Sterre Leufkens for research into linguistic redundancy. Data involve attestation of four types of concord in a 50-language sample. The sample was copied from Rijkhoff (2002). 

Used symbols with their meaning:
+ >> this type of concord is attested in the language under consideration
- >> this type of concord does not exist in the language under consideration
n.a. >> not applicable, meaning that this type of concord cannot exist in the language under consideration because one of the constituent parts is not present
n.d. >> no data, meaning that no conclusive data could be found about the existence of this type of concord in the language under consideration.
