Note: H is the Shannon diversity index. The number of nationalities is counted from the district-by-nationality table in all three columns: the province value is the union over that province's districts and the national value is the union over the 250 districts. The yearbook began listing every nationality at the district level in 2014, so counts before that year are cut to the top 19 plus other. The national value is the sum of the 250 districts and equals the yearbook's national total.

Values can break in years when district boundaries changed. Types are set by dividing the work, study, and marriage shares among foreign residents without Korean nationality by the national benchmark (38%, 16%, 15%).

Source: Open dataset, indicators calculated from it.

Note: Shannon diversity (H) measures how evenly nationalities are mixed, and a higher value means several nationalities of similar size. HHI moves the other way and rises as one or two nationalities dominate. Evenness rescales H to a range of 0 to 1. The rank is the position among the 250 districts ordered from the largest. The province column treats the whole province as one unit. It differs from the mean of the district values.
