In September 2012 de Volkskrant started with datajournalism. Datajournalist Sybren Kooistra had to support the newsdesk with new journalistic investigations involving data.
This is a collection of five pieces that Sybren Kooistra has made in the last year (April 2013 to April 2014) that showcase different types of data collection and analyses. It involved scraping, RUBY programming, EXCEL, SPSS, ‘datajournalism in the wild’, negotiations and surveys. Other subjects of his work during this year include crime, politics, lobbyists, household income, social housing, expensive infrastructural projects, fraud in long-term care insurances, elections and sustainable energy.
