1991 Block-Face Data File (BFDF) Re: corrections to be made on files CA550.BFD and CA505.BFD March 2001, Geography Division, Statistics Canada. It has been found that in the 1991 Block-Face Data File CA550.BFD (Guelph) there is an extra record at the top of the file: LADYSMITH CH __________1839711550664661 10 324052355820355050700.0845.74606 76.3226 This record also includes an extra character "" and should read as follows; LADYSMITH CH __________1839711550664661 10 324052355820355050700.0845.74606 76.3226 When a population and dwelling count was done on the CA550.BFD file (Guelph), it was found to exceed the established popcount by 10 and dwelling count by 3 respectively. Therefore, we recommend that this record within the CA550.BFD (Guelph) file should be deleted. Upon reviewing CA505.BFD (Ottawa-Hull), it was found that the total population was short 10 and the dwelling count was short 3. This record has all the attributes to belong to the Block-Face Data File for Ottawa-Hull; CA505.BFD. Therefore, we recommend that this record should be added to the CA505.BFD (Ottawa-Hull) file.
