Toronto’s Human Centre, part 2: by neighbourhood

Beware throwaway comments; that way overanalysis lies. This was a challenge.

Taking the 2006 neighbourhoods population into account, the human centre of Toronto is at 43.717955°N, 79.389828°W …

… pretty close to the one I’ve already worked out by ward.

Scraping the neighbourhood populations was hard. For the 140 neighbourhoods, the data is stored in a pdf with the URL like http://www.toronto.ca/demographics/cns_profiles/2006/pdf1/cpa124.pdf (in this case, 124; Kennedy Park, represent!). The population number is stored in a table on page 2 of each pdf. I used pdf2xml to convert the files into something parseable.

Of course, the tables weren’t exactly in the same place in every file, so I took a sample of 10% of the files, and worked out the X & Y coordinates of the population box. pdf2xml spits out elements like

<TOKEN sid="p2_s427" id="p2_w417" font-name="arialmt" serif="yes" fixed-width="yes" bold="no" italic="no" font-size="7.47183" font-color="#000000" rotation="0" angle="0" x="299.739" y="122.117" base="129.634" width="22.7692" height="9.94501">17,050</TOKEN>

Yes, I should have used an XML parser, but a Small Matter of Perl got me 126 out of the 140 matching. The rest I keyed in by hand …

Table after the jump.

The total population I scraped is within 0.1% of the official 2006 population of the city, so I’m good enough.
