In the attached factsheets, we list detailed historial Olympic information for every IOC Member Nation that has previously competed at the Olympic Winter Games and that will compete in Sochi, as of 27 January 2014. There appear to be 88 qualified NOCs that have met IF quota requirements as of 24 January, and have accepted them (the previous record for a Winter Olympics is 82 in 2010 at Vancouver). Unfortunately, after reallocation of some quotas, only the skiing federation (FIS) has published the final quotas as of 26 January. We have tried to list below the sports for which each NOC has qualified but there is a small chance, with reallocations, that there may be minor differences in the final allocation by sport.
There are seven nations that will compete in Sochi that have never before competed at the Olympic Winter Games – Dominica, Malta, Paraguay, Timor-Leste (East Timor), Togo, Tonga, and Zimbabwe. Their factsheets have been published previously on olympstats.com – see http://olympstats.com/2014/01/23/new-winter-olympic-nations-for-sochi/, which came out on 23 January.
One problem nation is listed below and that is DPR Korea (North). They have not qualified any athletes for Sochi (including Dennis Rodman). They had the 1st and 2nd reserves for pairs figure skating but those do not appear to have been chosen by final reallocation of quota spots by the International Skating Union (ISU). However, yesterday (26 January), DPR Korea has petitioned the IOC for redress to allow them to have Olympic athletes compete in Sochi. So they are included below but it is unknown if they will compete.
