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.收入维度的聚合基于全球收入四分位法进行划分，该划分方式大致对应世界银行（World Bank）的收入分组标准。收入四分位分组在时间维度上保持固定，即某一国家在2010年的收入归类将持续至2050年。相关系数将在收入分组层级上进行计算。
