Our figures for the area of units as measured in acres are always numbers that were listed in census reports, while all areas measured in hectares have been calculated by us from our boundary maps. A small amount of the variation in persons per acre therefore results from changes in how accurately the country had been surveyed. Spectacular changes in density from one census to the next are usually the result of major boundary changes.
