This note describes the origin, the history, structure and characteristics of a recently constructed Flemish (the Northern, Dutchspeaking part of Belgium) historical-demographic database. The so-called Antwerp COR*-database offers a unique combination of features: it spans nearly seven decades (1846 to 1920) and consists of information drawn from the population registers and the vital registration records (birth, marriage, and death) of the whole district of Antwerp. Every person whose family name starts with the letter combination COR* is selected in the database. The database covers three linked generations and contains micro-data on the individual level (life courses), intermediary data on family patterns, and macro-data on ecological characteristics.
