Total Persons Persons as a fraction of total persons, in Inner Sydney, Australia, according to the 2011 census results. Obviously this is an unusual thing to plot (persons/persons), but it's done as a measure of inconsistency of the numbers recorded in the census data packs. Total persons is calculated a few ways (e.g. males+females), and I use the maximum value found across these measures as my normalizer. The good news is that the variation in persons/persons is not large, as the scale on this map shows - nearly all areas have a value near 1.00.  The map is divided into geographical subdivisions by Statistical Local Area. Note the split scale above and below the median value.
