The weighted average of the number of Decayed, Missing or Filled teeth among the 12 years old in a country (DMFT). It is meant to reflect the prevalence of caries in a population.

HOW TO JOIN WITH METADATA

• Concepts (labels/units)
– Use the concept id bad_teeth_per_child_12_yr to look up labels and units in @gapminder.metadata.concepts.
SELECT * FROM @gapminder.metadata.concepts WHERE concept = 'bad_teeth_per_child_12_yr'.

• Countries and names
– Join your datapoints on geo to @gapminder.metadata.entities_geo_country to get readable country/area names
(e.g., name) and membership attributes such as world_4region, income_groups.

• Regions and other group labels
– After you have a region code from the country table (e.g., world_4region),
you can join to:
· @gapminder.metadata.entities_geo_world_4region on world_4region → region names/colors/shapes
· @gapminder.metadata.entities_geo_world_6region on world_6region → region names
· @gapminder.metadata.entities_geo_income_groups on income_groups → income group names

Example:
SELECT d.time,
c.name AS country,
d.bad_teeth_per_child_12_yr AS value
FROM @gapminder.bad_teeth_per_child_12_yr.bad_teeth_per_child_12_yr_by_geo_time d
LEFT JOIN @gapminder.metadata.entities_geo_country c ON d.geo = c.country;
