PSU maps (F01 cluster diagrams)
PSU maps are generated using Generalized Mapping System (GMS) software in place since 2009. Geography Division has also developed a cluster viewer application. This is an electronic map of Canada with a number of features that allow the user to interactively zoom to specific PSUs, change the range or scale of the map, as well as to create .pdfs files that are similar to those produced by the GMS. A table of PSUs along with the relevant information for the map legend is one of the key GMS inputs. All maps are carefully checked before shipment to the Regional Offices (RO). Map sizes and inset boundaries are automatically generated but may not be appropriate in all cases. Clerical verification of the PSU maps is done to improve the final product. The GMS has tools that allow adjustment of the map size, as well as deletion or creation of insets. Below is an example of a PSU map. The legend is explained on the next page, followed by the inset map (portrait orientation).
LFS F01 Cluster diagram
Description for LFS F01 Cluster diagram
Highlights of what is displayed visually, the goal of map, text within the map:
The map displays the boundary of one specific PSU, with the area within the cluster shown in yellow and the area outside shown in green. The boundary is a dark dotted line. Water and streets are shown and labeled. Blocks within the PSU have a grey boundary and are given numeric labels displayed within circles. A portion of the map is covered by a semi-transparent rectangle labeled “Inset 1”.
Legend:
Artificial IDs, dates, and counts have been used in this example.
Sample Identification is the PSU ID, fake for this example, (stratum 1001306; design type 01; PSU 030; rotation group 2).
AR Group: Classifies the PSU based on their membership in the mail-out for Census and expected AR listing quality (0 = mail-out, high quality; 1 = non-mail-out, high quality, 2 = non-mail-out, low quality)
Count: Design count of the number of households in the PSU (334)
SVID: Survey ID of the first survey to use the PSU (8090 is the CCHS, 10440 is the LFS, etc.)
RST: First random start used for dwelling selection
ISR: PSU level inverse sampling rate used for dwelling selection
Date: Date of first use of this PSU by any survey
LFS_Date_EPA: Date of first LFS use. If SVID is 10440 = LFS, then LFS_Date_EPA is set to 0 by convention.
Location: A Canada Post municipality. Usually, the most frequent one appearing the prospective dwelling list.
CT: Census Tract code from Census base at the time of PSU introduction. This will be Census 2011 initially and Census 2016 later on.
DA: Dissemination Area code from Census base at the time of PSU introduction. This will be Census 2011 initially and Census 2016 later on.
N1 of / de N2: Map number and total number of maps for this PSU (1 of 2). Two PSU maps means there is one main map (number 1) and one inset (number 2).
Inset: For inset maps, the inset number. Inset does not appear in legend of main maps.
Special Remarks: Extra pertinent information about the PSU – usually blank.
Symbol legend shows how geography features are displayed.
North symbol always points up.
Scale of the map.
Print Date: On landscape maps, Print Date appears in the lower left, rotated and outside of legend. On portrait maps, Print Date appears in the bottom centre, below the legend.
Area outside PSU is green; area inside is yellow.
Blocks are numbered and circled.
Starting point is an asterisk.
Inset rectangles are dotted gray.
Neighbouring PSUs are labeled. Specific PSU blanked out in the example.
Address ranges are shown along roads.
Street labels are more legible on the actual maps than on these images.
Maps can be oriented either landscape (legend at left) or portrait (legend at bottom).
The possible main map sizes are 11” x 17”, 17” x 22”, or 22” x 34”.
All insets are 11” x 17”.

Highlights of what is displayed visually, the goal of map, text within the map:
The map displays a portion of the other cluster diagram (the inset area) in greater detail. Area within the PSU is shown in yellow and the area outside the PSU is green. The boundary is a dark dotted line. Water and streets are shown and labeled. Blocks have a grey boundary and are given numeric labels displayed within circles.
