Normalising Nationalities (via a good ISO-3166 Country List)

A recent development has seen the acquisition of some very large data sets which contain a "nationality" column. Unfortunately the contents of that column are inconsistent; sometimes the country name is used, sometimes the nationality (or demonym) is mis-spelled. We decided therefore to normalise the nationality columns, and to do so by converting them to the two character ISO-3166 country code list; common codes are GB, US, AU, CA, CN, ES etc.

Unfortunately many of the lists available are incomplete, out of date or have errors, We have therefore compiled a new ISO-3166 list which includes, where possible, up to three demonyms for each row. These include some common mis-spellings as well as the genuine alternatives. The data referred to above includes the unpleasant sounding nationality "Turk" as well as "Turkish", so both denonyms are included in the list for the sake of completeness.

The latest changes to the world's countries are represented here, including creation of South Sudan, and the separation of Serbia from Montenegro. Burma was renamed by its government 25 years ago, but the old name is still commonly used by news agencies and other bodies, so our list gives the official name in brackets after the common name. We'd also like to say a big hello to the people of The Republic of the Union of Myanmar today.

The table includes some rows which are not sovereign countries, such as Guam or Jersey. The table is sorted by ISO-3166 code.

We have sucessfully used this table to normalise the nationality data in the aforementioned large data sets, and the new column is a simple 2 latin character code, which represents a worthwhile space saving excercise in our large database, in addition to the new consistency of the data.

One problem with this approach is the occasional duplication of denonyms which would prevent the remapping of nationalities back from the ISO-3166 country code; look at The Virgin Islands (both countries) whose inhabitants are both described as "Virgin Islanders". This description fails to clarify to which Virgin Islands the person belongs, so it is insufficient to accurately determine the ISO-3166 code anyway. We have special cased our normalisation in this instance.
