Map of the Week: The adoption disclosure registry
Map: Birth parents
This week's maps look at Ontario's adoption disclosure registry, mapping birth parents and adoptees by postal code, as a rate per 1,000 of population.
There are over twice as many adoptees (28,300) on the registry as birth parents (12,990):
About 86% of the people on both lists are still Ontario residents.
Some of our maps show an immediate, obvious pattern; these really don't, except that both are more small-town and northern than not.
Birth parents cluster in the mining belt of northeastern Ontario (North Bay, Eliot Lake, Timmins and Kirkland Lake all have clusters). In the south, inner-city Hamilton, the St. Catharines-Thorold-Niagara Falls area, London, Brantford, Sarnia, Peterborough and Oshawa have clusters; Ottawa has a cluster centred in Vanier and Westboro. Toronto doesn't really pop out on the map at all.
The adoptees are more scattered, though there are clusters in Sudbury, North Bay, Kirkland Lake and Timmins. In the south, the same St. Catharines-Thorold-Niagara Falls area pops out, as does K-W, Sarnia, Peterborough, Belleville, Kingston and Ottawa.Once again, Toronto has no visible cluster.
The data was released by the Ministry of Community and Social Services in response to an access-to-information request.
