Cross-country correlations tracking the change in country-level overshoot (arithmetic mean of food group category-level overshoot) between 2010 and 2050 and the change in imports per capita between the years 2010 and 2050.

Aggregation by income is via global income quartiles, and are roughly analogous to World Bank income groupings. Income quartiles groupings are static over time (i.e., the income designation of a given country in 2010 persists through 2050). Correlation coefficients are calculated at the income group level.
