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 based on the 1,601,452 people allocated to districts and differs from the national total of 1,604,725.

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. Table 6 counts only the categories used for the density figure, so the two numbers can differ. Organizations are ordered by the number of services they provide, and by name where that is the same. Organizations with no address on record come last. The full list and its filters are in the Service map.

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.
