G9A vs G9B

Quebec

This page does not pick a winner. Every row shows two measurements and the gap between them. There is no score, no tally of which area “wins” more categories, and no overall result — those would be a rating of two places and the people who live in them, assembled by the layout.

Both areas are forward sortation areas, and every figure describes the whole of one. Crime is not shown here: it is reported at the metropolitan level, so for two areas in the same city it is usually the same number twice. It is on each area’s own page, with the geography it describes.

Selected 2021 Census figures for G9A and G9B, with the national figure for scale. The last column states the gap between the two areas as a direction and a size, never as a preference.

Counts for each area. These describe the place and are not compared as ratios.

Share of each area’s residents with an amenity within reach, weighted by where people live. A blank is a coverage fact, not a zero.
Amenity	Within	G9A	G9B
Grocery store	1 km walk	89%	57%
Public transit	1 km walk	97%	90%
Park	1 km walk	97%	74%
Pharmacy	1 km walk	69%	11%
Child care	1.5 km walk	99%	96%
Primary school	1.5 km walk	95%	51%
Secondary school	1.5 km walk	58%	22%
Library	1.5 km walk	45%	14%
Health care	3 km drive	99%	99%
Employment	10 km drive	100%	100%

These measure how close an amenity is, never its quality. A school 500 m away is a school 500 m away — nothing here says anything about the school itself.
The proximity index is scaled against all of Canada, where 1 is the single most well-served block in the country and the national average is close to zero. It is useful for comparing places and misleading as a score.

What tenants pay, from CMHC’s survey of purpose-built rental buildings. The two areas may sit in different survey zones, or one may not be surveyed at all — that is a coverage fact and is stated rather than left blank.

The air quality index is a reading at the nearest station, which may be far away — the distance is shown because it decides whether the reading describes the area at all. Facility counts are reported releases within 10 km.

G9A: The nearest Air Quality Health Index location is Quebec, 116 km from G9A. That is far enough to be a different airshed, so its reading is not shown here as though it described this area. The index is published for about 130 communities and zones, not continuously across Canada.
G9B: The nearest Air Quality Health Index location is Montréal, 118 km from G9B. That is far enough to be a different airshed, so its reading is not shown here as though it described this area. The index is published for about 130 communities and zones, not continuously across Canada.

This page carries the figures the two areas can be set against each other on. Each area’s own page has the rest — including crime, the boundary map, and every source note and caveat in full.
