census_geography_bc

Usage

These scripts take geographic boundary files made available by Statistics Canada (under the Statistics Canada Open License), and convert them to .RDS files, which can be read into R and used for mapping etc.

Boundary files should be downloaded from this site:

• Boundary files

Folder structure within this project is

• \scr\ -- for scripts

• \geography\

  • (geolevel)_canada -- for the source shape files and a national *.RDS file for that level of geography

  • \bc_geog -- for all B.C. files (which are sub-sets of the national .RDS files)

Example: Census Metropolitan Area

File lcma000b16a_e.zip downloaded from 2016 Census - Boundary files, after selecting "Census metropolitan areas and census agglomerations" in the "Cartographic Boundary File" column.

This file is then saved to folder \geography\cma_canada, and unzipped.

The following script will

• open the file (using the {sf} package),

• save it as an .RDS file in the above folder,

• filter only the B.C. regions (using the provincial code of "59"), and

• save the B.C. file in \geography\bc_geog.

saveRDS(canada_cma, here("geography", "cma_canada", "canada_cma.RDS"))

# filter B.C. geography

bc_cma <- 
  canada_cma %>%
  filter(PRUID == "59") %>%
  mutate(PRUID = fct_drop(PRUID))

saveRDS(bc_cma, here("geography", "bc_geog", "bc_cma.RDS"))
