BLOCK-FACE DATA FILE (BFDF)

Description - Datasets - Example - back to Geographic Census Data Index

Description:

The information in this file uses the smallest geographical unit available from Statistics Canada,
namely the block-face in urban centres covered by Street Network Files. A block-face is one side
of a city street between two consecutive intersections.

Block-faces are available where there is Street Network File (SNF) coverage, that is, for large urban
centres with a population of 50,000 or more in the urban core. The 1991 & 1996 Block-face Data
Files are available for 25 census metropolitan areas (CMA) and 18 census agglomerations (CA).

In some cases, only portions of CMAs/CAs are covered by SNF; thus some urban centres may be
only partially covered by the Block-face Data File.

The block-face information includes street name (including street type and direction), address
range, geographic codes, x,y coordinates for a representative point and 1991 and 1996 population
and dwelling counts. The total number of Block Face Data Files for 1991 is 763,626; the total number
of 1996 BFDFs is 817,734. (Statistics Canada 1996)

Datasets:

The Data are available in ASCII format with Latitude / Longitude coordinates. In the TDR the following
products are stored:

Due to space constraints, the 1996 files are zipped and must be unzipped before using.
