About the data
Trade data comes from the United Nations Comtrade website. Dollar amounts are inflation-adjusted to 2015 dollars, using the World Bank's North American inflaction adjustment table. Commodities are classified in accordance with the Harmonized Tariff Schedule taxonomy and are aggregated at the Section or Chapter level, with the exception of crude oil (Heading 2709). NAFTA country trade data is consistently available only from 1990 on, and prior to 2010 is only available at annual intervals.
