Create a correspondence table between any two geographies

Usage

make_correspondence_tbl(from_geo, to_geo, mb_geo = get_mb21_pop(), ...)

Arguments

from_geo: An {sf} POLYGON object.
to_geo: An {sf} POLYGON object.
mb_geo: An {sf} POINT object where the points are the centroids of a small area (intended to be mesh blocks but can be any other space that's small enough to be useful. Should also include a column, Person, with the population within that area. Defaults to use Mesh Blocks (2021) and with 2021 census data. See get_mb21_pop().
...: other, ignored arguments.

Value

A tibble.

Examples

make_correspondence_tbl(
  from_geo = get_polygon("sa22016", crs = 7844),
  to_geo = get_polygon("sa22021", crs = 7844),
  mb_geo = get_mb21_pop()
)
