## Core schema reference

The [core schema](https://developers.google.com/maps/documentation/population-dynamics-insights/reference/core-schema.md.txt) defines the table structure for the Population
Dynamics Insights dataset. It details the available columns, including primary
identifiers (`geo_id`), spatial metadata for interoperability, and the
330-dimensional embedding vector itself (`features`).

## Geographical resolution reference

Because administrative boundary types vary globally, the [geographical
resolution reference](https://developers.google.com/maps/documentation/population-dynamics-insights/reference/geographical-resolution) maps the generic dataset schema
fields (`administrative_area_level_1` and `administrative_area_level_2`) to the
local geographic equivalents in your target market (such as states, provinces,
or districts).
