"Padrón de población de Aguascalientes", compiled in 1792 by Felix Calleja
According to the book by Jesús Gómez Serrano "Los españoles en Aguascalientes durante la época colonial", in 1792 visiting dignitary José Menéndez Valdés compiled a population census of the district of Guadalajara, which underlines the importance that Aguascalientes had as a final destination for many spanish and portuguese immigrants. Along the same lines, the local "padrón de población" compiled by Félix Calleja in 1792, confirms the data gathered by Menéndez Valdés and includes the name, origin, age and occupation of european immigrants or "españoles" that lived in Aguascalientes.
