tongfen_estimate_ca_census function implements the full pipeline to estimate census data on custom geographies.
As an example, we estimate the share of people in low income in Vancouver’s skytrain station neighbourhoods. The station neighbourhoods are available as part of the
Next we assemble the required metadata for the share of people in LIM-AT and estimate the share on our custom geography using DA level census data. Here we pull the census data based on CT level intersections to preserve API points.
<- meta_for_ca_census_vectors(c(limat = "v_CA16_2540")) meta <- tongfen_estimate_ca_census(station_buffers,meta,level = "DA",intersection_level = "CT", station_data quiet=TRUE, na.rm = TRUE)
The result is a dataframe with estimates of the share of the population in LIM-AT for each buffered station, which we can plot or use otherwise for further analysis.
