Map(s) of the Week: Childbirth, week 1
|TARA WALTON/TORONTO STAR|
This week begins a four-part series on childbirth in the GTA. (It will be followed by a shorter series on death.)
The information comes from data I bought from the Office of the Registrar-General, which was taken from the Statement of Live Birth form (.pdf) which is filled out when a child is born in Ontario.
All the maps are based on the first three characters of the postal code of the mother, and show data from 2007, the most recent year available.
This week's maps look at parental age at birth: average age of mother, average age of father/other parent, and the average age difference.
First, the average age of mothers (map).These are not necessarily first births, just births occurring in 2007.
The map itself shows a striking pattern, with high maternal ages in a belt between Yonge and Leslie south of the 401, and low maternal ages in another belt to the west roughly between Keele and Weston Road and northwest into Rexdale. In Peel, maternal ages are higher along the Mississauga waterfront, lower away from the lakeshore, and lower still in Brampton.
Here are the top ten neighbourhoods for average maternal age:
|M4V||Casa Loma/southern Forest Hill||34.29|
|M3B||Bridle Path/Don Mills||34.09|
|M2P||York Ridge/St. Andrew’s||34.02|
and the lowest 10:
The average age of father/other parent map shows a strikingly similar pattern.
Eight out of the top ten areas for father/other parent age are also on the table we just saw, with M8X (The Kingsway) topping both lists. The same three Oshawa neighbourhoods are on the bottom of both lists, in the same order:
|M3B||Bridle Path/Don Mills||37.13|
|M2P||York Ridge/St. Andrew’s||36.68|
|M4V||Casa Loma/southern Forest Hill||36.43|
Here are the lowest 10:
|M5H||North of downtown financial district||31|
The map of parental age difference does show a pattern, in that there is a cluster of low age difference in the north-central part of the city, and high age differences concentrated in the northwest, the east downtown and Thorncliffe Park, and much of Scarborough. The 905 is more uniform.
In all 194 GTA postal areas, the average age of the father was higher than the average age of the mother.
Here are the highest 10:
|M9R||Willowridge/The Westway/Richview (E of 401/427)||4.91|
|M1L||Oakridge/Clairlea (southeast Scarborough)||4.9|
|L5K||Mississauga, Dundas and Winston Churchill||4.87|
|M1G||Golfdale Gardens (Golf Club Rd/Lawrence)||4.77|
|M1P||Scarborough Town Centre||4.67|
and the lowest 10:
|L0P||Campbellville and area||1.64|
|L1M||Rural north Whitby||1.58|
|M5H||North of downtown financial district||0.91|
