Census Trends
Scope of Census
So far the Venice Project Center has organized pages on data from the years 1991, 2001, and 2011. These data have a minimum resolution unit called a census tract, which is a semi-arbitrary subdivision - it is generally of a certain size, and does not cross the borders of any island, but it is not by definition (though it may be by choice or coincidence) a reflection of an actual physically or culturally distinct area.
