Following up on yesterday's post "The case of the disappearing determiners", Gosse Bouma sent me some data from the CGN ("Corpus Gesproken Nederlands"), about determiner use in spoken Dutch by people born between 1914 and 1987. According to the CGN website,
The Spoken Dutch Corpus project was aimed at the construction of a database of contemporary standard Dutch as spoken by adults in The Netherlands and Flanders. […] In version 1.0, the results are presented that have emerged from the project. The total number of words available here is nearly 9 million (800 hours of speech). Some 3.3 million words were collected in Flanders, well over 5.6 million in The Netherlands.
It's not clear to me exactly when the recordings were made, but the project ran from 1998 to 2004.
Gosse sent data focused on the word de, which is the definite article for masculine and feminine ("common") nouns in Dutch, cognate with English the. (The definite article for neuter nouns, het, is less frequent and also can be used as a pronoun.)
The results are similar to those that I reported earlier for English: Older people use the definite article more frequently than younger people (at least for people born in the 1950s onwards), and at every age, men use the definite article more than women.
