Survey of Organisations Offering Health Complementary Coverage (OC Survey) 2011 to 2019 (2011-2016 revised)

The purpose of the DREES “OC” survey is to ascertain the activities of organisations offering complementary health coverage, the population they cover, the guarantees they offer, and their pricing methods. The survey aims to describe as fully as possible the “heart” of the complementary health market, by questioning organisations about their most subscribed contracts, individually and collectively. Since 2019, the scope of the contracts investigated has been extended to a selection representative of the ten largest contracts of each type (collective, individual, over-complementary) compared to all three largest contracts before. The 2019 vintage presents, as a result, a break in series. In order to be able to analyse developments in 2016 and 2019, the 2019 indicators are complemented by the “restricted 2019” indicators corresponding to the reduced scope of the three largest contracts. However, developments should be interpreted with caution in view of a smaller number of such contracts in 2019. This broadening of the scope is accompanied by a methodological change in the calculation of the weights of the contracts surveyed, which leads to a revision of the series of previous editions (thousands 2011, 2013, 2014 and 2016).
