Report Chaos Just Broken Out Over Immigration Data in House prices and the economy Posted November 7, 2007 Wrong. 7% is way above the inflation figures like CPI which are innacurate anyway. A fair measure of inflation would probably be 10-12%. A fair measure of inflation would include basic expenses like food, accomodation and bills. Items that I think aren't in the CPI basket. An increase of 7% a year seems easily fair to me. Ok, if you do not like CPI forget CPI, but RPI also has always been lower than 5% recently. How do you come up with 10% - 12%? have you got a link or a reference? It seems really really high!
