G8Z 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 G8Z 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.
Measure	G8Z	G9B	Canada	Difference
Median household income	$47,600	$87,000	$84,000	G8Z is 45% lower than G9B
Median after-tax income	$42,400	$74,000	$73,000	G8Z is 43% lower than G9B
Median age	45.6	44	41.6	G8Z is about the same as G9B
Unemployment rate	8.3%	4.2%	10.3%	G8Z is 98% higher than G9B
Low income (LIM-AT)	23.6%	6.6%	11.1%	G8Z is 3.6× higher than G9B
Average household size	1.8	2.3	2.4	G8Z is 22% lower than G9B

How each area sits against the city or province around it — a different geography on each side, named in every cell. Read down a column, not across: the two columns are measured against different places and a bigger gap in one says nothing about the other.

G8Z is measured against Trois-Rivières, the metropolitan area holding 100% of its residents.
G9B is measured against Trois-Rivières, the metropolitan area holding 100% of its residents.

Counts for each area. These describe the place and are not compared as ratios.
Measure	G8Z	G9B

Population	13,972	18,680
Private dwellings	7,785	8,252
Land area	8.3 km²	83 km²

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	G8Z	G9B
Grocery store	1 km walk	93%	57%
Public transit	1 km walk	100%	90%
Park	1 km walk	97%	74%
Pharmacy	1 km walk	50%	11%
Child care	1.5 km walk	100%	96%
Primary school	1.5 km walk	100%	51%
Secondary school	1.5 km walk	59%	22%
Library	1.5 km walk	31%	14%
Health care	3 km drive	100%	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.

CMHC does not survey a rental zone covering either G8Z or G9B. The survey covers centres of 10,000 people and up, so there is nothing published for either area.

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.

G8Z: The nearest Air Quality Health Index location is Quebec, 116 km from G8Z. 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.
