Map of the Week: Ontario registered organ donors

Map: Ontario registered organ donors by postal code, February 2010

This week's map looks at rates of organ donor registration in Ontario. A link to a fully interactive version is above. The results are discussed more fully in an article in today's paper..

The map shows that Ontario residents sign up for the province's organ donor registry at very different rates, and that the rates show clear geographic patterns.

Parts of the GTA have have very low rates. The pattern is dramatic. The lowest-ranking 50 postal codes out of about 500 in all Ontario all cluster in northwest Toronto and the nearby part of Vaughan, and in Scarborough and the nearby part of Markham:

By contrast, northeastern Ontario shows far higher rates, with a belt stretching from Muskoka through Sudbury and North Bay and north of Lake Superior showing rates over 30%. A top 10 list of Ontario's 500-odd postal codes includes two different neighbourhoods in Timmins and two different neighbourhoods in North Bay.

These are real regional differences with sharply defined clusters. The question is: what lies behind them? At first I wondered whether it was local differences in the approach taken when health cards are renewed, but apparently this is supposed to be done uniformly across the province.

So these are real choices, rooted in a complicated mix of attitudes about death, the body, strangers, medicine and so forth.

(What was your experience when you renewed your health card? Let us know in the comments.)

Within Toronto, the city generally has rates under 10%, except for the inverted-T shape of the older neighbourhoods of the former City of Toronto, which have rates between 10 and 20%. York Region has rates below 10% south of a line more or less at King-Vaughan Road and Stouffville Road, and between 10-20% north of that. Much of Oakville has rates over 20%.

The Hamilton area has generally higher rates, with Dundas, Ancaster and the downtown neighbourhood south of Main St. W. showing rates over 30%.

Map of the Week: Property crime by census tract

SHUTTERSTOCK

Map: Property crime by census tract, 2006

This week continues our census-tract-based crime map series with a look at property crime.The data came from Statistics Canada by way of the Toronto police.

The pattern is different from last week's violent crime map, though many of the top neighbourhoods are the same.

Property crime is much more diffuse than the clear pattern in last week's map. There is a concentration in the higher-density parts of the old city, with higher rates in a rough rectangle south of Dupont/O'Connor between Roncesvalles and Victoria Park. As we found with the 2008 breaking and entering map, there is no very simple and obvious connection to income.

Here is a top 20 list:

1	5350003	SW Parkdale	8 on violence map
2	5350073	Greenwood/Gerrard/railway
3	5350316.03	Steeles/Jane/Finch/Gosford
4	5350194.03	Overlea Blvd/Thorncliffe Park
5	5350039	Queen/Dundas/Spadina/Bathurst	6 on violence map
6	5350180	NW of Victoria Park/Danforth
7	5350368	Lawrence/McCowan/Brimley/401
8	5350067	Winchester/Parliament/DVP/Bloor
9	5350356	SW of Lawrence/Markham Rd
10	5350032	Carlton/Dundas/Jarvis/Parliament	1 on violence map
11	5350054	Bloor/Dovercourt/College/Brock
12	5350249.05	Albion/Kipling/Martin Grove/Mt Olive

19	5350308.02	Finch/Bathurst/cemetery/Senlac
20	5350080.01	Danforth between Main and Woodbine

The crimes tracked in this map were:
Breaking and entering
Theft of a motor vehicle (or inside vehicle), theft of bicycles, in possession of stolen property
Theft over $5,000, theft under $5,000 and shoplifting over and under $5,000 frauds
Mischief (against property or causing property damage)

More background to the study is here. The maps toward the end of the study track particular offences, and are worth a look.

Now we are five

Mike Pegg at Google Maps Mania points out that this is the fifth anniversary of the first Google Maps mashup, announced in a post on Craigslist:

Keep in mind that an API for Google Maps did not yet exist. This was the first act of its kind to mash data up and add it to a Google Map and as far as record keeping goes, is, the first Google Maps hack, or mashup. I've always tended to call it a hack since it's just more bad-ass and disruptive than a "mashup" sanctioned by a proper API. :)

I think we can hold our heads up as reasonably early adopters - our first serious project, a homicide map backdated to the beginning of the year, launched in mid-2005, a collaboration between editors Brett Smith, Chris Carter and me.

Map of the Week: Violent crime by census tract

IAN WILLMS/TORONTO STAR

Map: Violent crime by census tract, 2006

Regular readers of this blog will have seen several iterations of words to the effect that a map is being produced because improved tools have made it possible.

When Statistics Canada published a file last year of 2006 crime rates for Toronto broken down by 531 census tracts, it wasn't possible to map it on line, and I more or less forgot about it until this week until I found it in an ideas spreadsheet. (Yes, I have an ideas spreadsheet - doesn't everybody?)

The data is from 2006, but very finely textured. I can only imagine the work involved. The authors explain:

Incidents that were located on the boundaries of many census tracts were divided in that number of census tracts. For example, an incident located on the boundary of 3 census tracts was counted as 0,333 incidents in each of the 3 census tracts.

As far as I can tell, the researchers ended up mapping 26,022 violent crimes. Property crimes were dealt with separately, and will be the subject of a different map.

Also, there was an attempt to relate crime rates to both residents and visitors in an area. One problem with our neighbourhood-based crime maps is that they divide the number of reported crimes in a neighbourhood by the number of residents. I suspect that this overstates the crime rate as experienced by residents in neighbourhoods with many outsiders, like those downtown. It's never been clear to me what to do about the problem other than to flag it for the reader.

1	5350032	Carlton/Dundas/Jarvis/Parliament

A string of neighbourhoods with high violent crime rates stretches south from Jane and Steeles more or less along Black Creek and the railway tracks south to Parkdale.

---

A large area centred more or less at Lawrence and Bayview has fairly low violent crime rates:

---

Another area with high violent crime rates starts in the east downtown and stretches east toward and past Victoria Park, with several areas of lower rates.

In an e-mail back-and-forth this week, Statistics Canada explained that the violent crimes tracked were:

Homicides: murders, manslaughters, infanticide
Attempted murders
Assaults
Sexual assaults, sexual offences (invitation to sex. touching, luring via computer, etc.)
Robberies
Criminal negligence causing bodily harm
Firearm offences: use of, discharge, pointing
Forcible confinements, kidnappings, abductions
Criminal harassment, uttering threats, threatening or harassing phone calls
Other violent violations: trafficking in persons, arson causing disregard for human life, intimidation, hostage-taking, incest, voyeurism, etc.

Tweaking the neighbourhood map

SIMON HAYTER/TORONTO STAR

Toronto Star neighbourhood map

Through much of the early part of last year, we were working on a Toronto neighbourhood map which was largely crowd-sourced: we produced a map and invited comments, then tweaked the map based on the comments, and so forth through several iterations. (You can follow the whole process here.)

The version published today has a few housekeeping issues sorted out - some boundaries have been tidied, the lines between areas have been thinned, and it is produced in a conventional .kmz format.
