The questions and purchase options in this crowd sourced list are extremely similar to the 'basket of goods' she was seeking. Prices are also pretty similar to 2008/2009 but a bit askew from today (particularly food, which over the past 5 years has experienced significant inflation).
Was there a surge of this type of information collection at the time (I can't recall anything of note online), or has a relocation / relocation-type consultancy released past data?
Expatistan: "Volkswagen Golf 2.0 TDI 140 CV 6 vel. (or equivalent), with no extras, new"
Numbeo: "Volkswagen Golf 1.4 90 KW Trendline (Or Equivalent New Car) "
I don't know. Not the same but very close and alike. I love Numbeo and this looks eerily similar.
Expatistan has only 1 accomodation data point (Monthly rent for 85 m2 (900 Sqft) furnished accommodation in EXPENSIVE area) while Numbeo give me information about different size apartments in and out of city center
We started collecting prices for different ones a while ago. We are now reaching the point where we already have enough data to include the new types of housing in the public index.
In fact, most places in the US (even the sunny bits) look cheaper to live in than Coventry. How sad.
