Usage

statcan_ivt_years()

Value

A tibble with one row per version: temporal (the URL parameter, e.g. "2017" for the 2016 long-form), census (the human label, e.g. "2016 Census - Part B (long-form questionnaire)") and census_year (the leading 4-digit year of the label as an integer). NULL (invisibly, with a warning) if the index could not be reached.
