A single SDG indicator (for example "3.4.1", NCD mortality) is
typically published as several series stratified by sex, age,
or cause. Different series may have different country and year
coverage. sdg_coverage() summarises year range and observation
count per (location, series) combination, so you can see which
series exist for an indicator and how each one is covered before
committing to a downstream analysis.
Arguments
- indicator
Character vector of SDG indicator codes (e.g.
"3.4.1").- area
Character vector of country/area codes. Accepts either ISO3 codes (e.g.
c("PHL", "FRA")) — converted automatically viaiso3_to_m49()— or UN M49 numeric codes (e.g.c("608", "250")) as returned bysdg_areas(). Do not mix the two formats in a single call. DefaultNULLreturns all areas. Unknown ISO3 codes are dropped with a warning before the network call.- year_from
Numeric. Start year filter (inclusive). Default
NULL.- year_to
Numeric. End year filter (inclusive). Default
NULL.
Value
A tibble with one row per
(location, series) and columns:
location(chr) — area code (geoAreaCode).series(chr) — SDG series code.year_min(int) — earliest year with data.year_max(int) — latest year with data.n_obs(int) — number of observations.Sorted by
locationthenseries. Empty input or service failure returns an empty tibble with the same five columns.
Details
Unlike the GHO availability helpers, this function is a
series-exploration tool rather than a payload-saving precheck:
SDG data is generally complete enough that GHO-style
has_data() / count() helpers add little value, so they are
intentionally not provided. The SDG API also offers no
payload-reduction option (no $select equivalent), so
sdg_coverage() calls sdg_data() internally and aggregates
the result client-side.
