# Global Import-Export Country Year Totals (1995-2024)

Annual country-level exports, imports, and trade balances, with year-over-year and three-year growth measures where available.

## What one row represents
one country and calendar year

## Included measures and context
- Exports, imports, and trade balance in US dollars
- Year-over-year export and import growth

## Metric notes
- CAGR is the compound annual growth rate across a multi-year period.
- Year-over-year growth compares a value with the previous year; a negative percentage indicates a decline.
- Fields marked USD are monetary values denominated in US dollars.
- Values ending in pct are percentages.
- Country fields ending in ISO3 use three-letter ISO 3166-1 country codes.
