The official statistical records on suicide are not reliable due to an under reporring of suicide cases. Considering that the true suicide count is the sum of the officia/ record plus the obscure cipher, an attempt was made to estimare the latter using a simple proporcional imputation formula. The official statistical records were re-analysed under the following racional: the category of violent death caused by acccident or intention, but where it could not be established for cerrain, served as a reservoir that contained the obscure cipher. Using this indirect technique, it was possible to determine that the percentage mean of the obscure suicide cipher (1970-1974) is lower than the showed in the literature.
