G9C vs G9H

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 G9C and G9H, 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	G9C	G9H	Canada	Difference
Median household income	$97,000	$75,000	$84,000	G9C is 29% higher than G9H
Median after-tax income	$81,000	$64,500	$73,000	G9C is 26% higher than G9H
Median age	40	44	41.6	G9C is 9% lower than G9H
Unemployment rate	7%	4.4%	10.3%	G9C is 59% higher than G9H
Low income (LIM-AT)	5%	9.9%	11.1%	G9C is 49% lower than G9H
Average household size	2.4	2.2	2.4	G9C is 9% higher than G9H

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.

G9C is measured against Trois-Rivières, the metropolitan area holding 100% of its residents.
G9H 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.

Private dwellings	1,636	6,345
Land area	18 km²	440 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	G9C	G9H
Grocery store	1 km walk	70%	62%
Public transit	1 km walk	99%	0%
Park	1 km walk	96%	73%
Pharmacy	1 km walk	28%	31%
Child care	1.5 km walk	99%	81%
Primary school	1.5 km walk	0%	62%
Secondary school	1.5 km walk	3%	0%
Library	1.5 km walk	0%	13%
Health care	3 km drive	99%	93%
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 G9C or G9H. 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.

G9C: The nearest Air Quality Health Index location is Quebec, 120 km from G9C. 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.
G9H: The nearest Air Quality Health Index location is Quebec, 108 km from G9H. 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.
