Verses of Scripture sung at Mass, instead of the Alleluia, from Septuagesima Sunday till the Saturday befor Easter; -- so called because sung tractim, or without a break, by one voice, instead of by many as in the antiphons.
The tract (Latin: tractus) is part of the proper of the Roman Mass, which is used instead of the Alleluia during Lenten or pre-Lenten seasons, and a few other penitential occasions, when the joyousness of an Alleluia is deemed inappropriate. Tracts are not, however, necessarily sorrowful.
A small, relatively permanent statistical subdivision of a county delineated by a local committee of census data users for the purpose of presenting data. Census tract boundaries normally follow visible features, but may follow governmental unit boundaries and other non-visible features in some instances; they always nest within counties. Designed to be relatively homogeneous units with respect to population characteristics, economic status, and living conditions at the time of establishment, census tracts average about 4,000 inhabitants. They may be split by any sub-county geographic entity. See tract.
