Rural population refers to people living in rural areas as defined by national statistical offices. It is calculated as the difference between total population and urban population.

HOW TO JOIN WITH METADATA

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

• 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.rural_population_percent_of_total AS value
FROM @gapminder.rural_population_percent_of_total.rural_population_percent_of_total_by_global_time d
LEFT JOIN @gapminder.metadata.entities_geo_country c ON d.geo = c.country;
