Auto’s en toeristen snelst stijgende bron van inkomsten voor Amsterdam

Het CBS publiceerde een artikel over de gemeentelijke belastingen in Nederland voor 2019 met een aantal interessante inzichten. In het artikel wordt Amsterdam apart genoemd als het gaat over toeristenbelasting en parkeerinkomsten, daarom heb ik gekeken naar de bijdrage van deze posten voor Amsterdam. Dat blijkt behoorlijk anders dan het totale beeld van Nederland. Waar voor heel Nederland de Onroerendezaakbelasting op 1 staat, is dat … Continue reading Auto’s en toeristen snelst stijgende bron van inkomsten voor Amsterdam

Which chart is best for your data?

The power of telling stories with data

Why should I A/B Test? I know what will work better!

We ask our colleagues on a weekly basis which content option performed better in an A/B test, inspired by a site called ‘whichtestwon’ (which seems to be out of operation these days). Sometimes the text is different, sometimes it’s a different picture, or just a different colour. We then looked at how good they were at guessing the winner. It turns out, my colleagues and … Continue reading Why should I A/B Test? I know what will work better!

It is … Continue reading Why? Why? Why? Why? Why?

To see if I could find the facts about this, I went to the Open Data Portal of the city of Amsterdam.. There, you can find the ‘Basisbestand Gebieden Amsterdam (BBGA)‘. I … Continue reading Are your neighbours young or old?
