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.

Note: this is the denominator behind the share in Figure 1. It counts Korean residents on the resident registration and does not include registered foreigners.

Note: Korean-Chinese and China together come to 59.6%. Seoul and the national columns give the share of that nationality among registered foreigners in each area.

Note: Only this table follows the MOIS count, which totals 450,888, and it covers a different population from the 265,544 registered foreigners MOJ counted the same year. Adding the two counts the same people twice.

Note: The share of each type among foreign residents in this district in that year. Table 5 gives counts for a single year and this figure gives the composition year by year. 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%).

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.

Note: This district, its province, and the national value share one axis. The province and national values are for the same year. Values can break in years when district boundaries changed.

Note: a marriage counts as multicultural when one spouse is a foreign national or a naturalized Korean. Statistics Korea does not split the wards of a large city, so a ward carries the value for the city named in the column header.

Note: neither agency splits the wards of a large city, so a ward carries the value for the city named in the column header.

Note: a count of organizations is not a measure of how much service is provided, and the size and scope of each organization are not in this list.

Note: Only organizations with an address in this district that serve people directly, that have not closed or gone dormant, and that have a website or social media account confirmed as their own are listed. An organization missing any one of the four does not appear, so one you know of may be absent. The table above counts only the categories used for the density figure, so the two numbers can differ.
