On 30 september, I posted the last article on Nieuws uit Amsterdam (News from Amsterdam). The website has been inactive since, apart from a message on 28 October formally announcing that the site is no longer active. As expected, the number of new followers of @nieuwsamsterdam on twitter dropped in October. Intriguingly, it started to rise again after that.
The list of new followers has been compiled from ‘You have new followers’ emails and may be incomplete. Graph may not work in older versions of Internet Explorer.
Dutch trade unions have a reputation for constructive dialogue, but that’s not necessarily what people expect of them. In the LISS Political Values study, some 6,000 panel members have been asked a number of times whether they agree with the statement ‘Trade unions should take a much tougher political stance, if they wish to promote the workers’ interests’. In the latest edition of the study, those who agree with this statement outnumber those who disagree by 2.6 to 1. This support for tougher unions holds for most subgroups (but not the self-employed and people earning more than 4,500 euros per month).
Support for tougher unions over time

Support for tougher unions, by group
Values higher than 1 mean that within that group, those in favour of tougher unions outnumber those who disagree. For example, among people with paid employment, the number of respondents in favour of tougher unions is 3.5 times as high as the number who disagree. Hover mouse over bar to see percentages.

I can’t say it’s a very good graph: some of the most intriguing aspects of the data have to do with changes over time (decline in some countries, rather large growth in Finland, implausible fluctuations in the Netherlands), which don’t show very well in my graph. Nevertheless, it feels good to have coded my first interactive D3 graph.
P.s. the graph may not be visible in older versions of internet explorer.
The habits of cyclists are shaping cities like Amsterdam. “There are many ATMs along the main bicycle path network”, urban planner Marco te Brömmelstroet told Vogelvrije Fietser, the magazine of cyclists’ organisation Fietsersbond.
The map above shows Amsterdam’s main cycle path network (provided by the city as open data) and the location of ATMs. It appears that many ATMs are indeed located near cycle paths. Exceptions include shopping areas such as the Kalverstraat, Gelderlandplein and Bijlmerplein. (I tried to calculate the distance between ATMs and cycle paths but I couldn’t get this to work in QGIS.)
The fourth assignment of the data visualisation course was to do something with this data on unemployment in US states, published by the Guardian Data Blog. My project could be summarised as ‘It’s the unions, stupid’.
P.S. I didn’t post my work for the third assignment on this blog. I’m afraid it wasn’t any good.
Update - Elsewhere, the impact of the bailout on the election is questioned as well.
