Lesbian and gay couples segregate from each other by neighbourhood in Quebec much more than in the rest of Canada, census data shows.
In Canada overall, of 399 census tracts with a high number of gay male couples, defined as more than 20 gay couples per 1,000 of population, 179 had no lesbian couples. Of these, 101, or 56%, were in Quebec - 81 in Montreal, 12 in Quebec City, and the rest in smaller centres.
That's a pattern it's hard to see elsewhere in the country. In other Canadian cities, lesbians and gay men show much more of a tendency to share the same geography.
Canada's highest census tract for gay male couples, a dozen or so blocks on the west side of Church St. centred on Wellesley St. W. in Toronto, has 255 gay couples and 30 lesbian couples. Montreal's top census tract for gay couples (west of Boul. Rene-Levesque and Papineau Ave.), on the other hand, has no lesbian couples.
Of Montreal's 20 highest census tracts for gay couples, 14 have no lesbian couples. The equivalent number in Toronto is seven, and in Vancouver, six.
The data is from 2006, as Cain notes.
The 2006 data is the most recent available. In 2011, Statistics Canada asked a question designed to count same-sex households, but the question was poorly designed and didn’t distinguish clearly between same-sex couples and two people of the same sex sharing accomodation. At the last minute (actually the morning of the census release), StatsCan decided not to release the data. My efforts to pry it loose with an access-to-information request were unsuccessful, in the end.
I'd like to see more recent data. I would ask if there are enough same-sex couples to confidently draw out actual trends as opposed to statistical hiccups, but I don't think that's a serious concern. Why would Québec be different on this front, I wonder?
