Most dissemination blocks in this diagram also contain a series of small polygons that represent dwellings, shaded light grey or dark grey. Each one of these dissemination blocks contains a dissemination block representative point located in its centre. In order to respect the dissemination area geography, the CSD boundary splits each of the dissemination blocks that it crosses, thus creating two dissemination blocks out of one.
In the bottom right quadrant, two dissemination blocks are crossed diagonally by a census subdivision (CSD) boundary.
Defined boundary plus#
Each block also contains a dissemination block representative point located in the centre of the block, which is represented by a large, bolded plus sign ( +). Each block contains blockface representative points, which are represented by a small 'x' and are centred on the inside of each blockface. The illustration is made up of a fictional grouping of streets and dissemination blocks. Each of these boundaries includes partial and complete dissemination blocks.
Two user‑defined boundaries are shown and are represented by thick grey lines. Figure 1.13 is a graphic representation of the information that is used to create user‑defined boundaries.
