Used and Explanatory Notes
The INDEC regularly uses the following symbols, that have in all cases the same consistent equivalence in substitution for or complementary to certain numerical data, although their use may be omitted in some specific instances where their insertion might also be appropriate:
||Provisional figure or data (Dato provisional)
||Figure or data equals zero (Dato igual a cero)
||Minute amount, less than half the order of the last digit
shown (Dato ínfimo...)
||Unrecorded data (Dato no registrado)
||Unavailable data at the time of reporting results (Dato no
disponible a la fecha...)
||Data not presented because of the nature of the subject matter
or of the calculation process (Dato que no corresponde presentar...)
||Confidential data according to the regulations on statistical
secrecy (Dato confidencial...)
||Estimated information (Dato estimado...)
||Non-profit institutions (Instituciones sin fines de lucro)
| Certain particular
symbols are also used when presenting data for which the Relative
Standard Deviation/Error (EER = error estándar relativo) has
been determined (otherwise, it might be concluded that data not showing
such complementary symbols have an RSD smaller than 10%):
The first of these two symbols is complementary (i.e. it is used adjoined to data),
whereas the other may be used either as a complement to or in substitution
for data (in this latter case, in substitution for omitted data).
In data tables where these symbols are used, it should be understood
that unmarked data have an RSD smaller than 10%.
||Data estimated from a sample with RSD between 10% and 30%
(Dato estimado..., con EER entre 10% y 30%)
||Data estimated from a sample with RSD larger than 30% (Dato
estimado..., con EER mayor de 30%)
| Time periods
||Indicates non-consecutive time periods showing (and including)
their initial and end points but where the data for at least
one included period are omitted (for instance, Ene 95 - Jul
96 [Jan'95 - July '96] indicates a series of months starting
in January 1995 and ending (and including) July 1996, where
data for at least one included month are omitted).
||Indicates consecutive time periods comprised between (and
including) the initial year or month or date and the end year
or month or date (for instance, 1985/1995 indicates a series
of data starting in 1985 and extending through 1995).
Coefficient (CV = coeficiente de variación): "The
variation coefficient is an indicator of data dispersion relative
to their average, spread usually expressed as a percentage without
a [dimensional] unit of measurement. The smaller the CV, the
less variation among observed data, which will in turn be better
represented by their average."
Standard Deviation/Error (EER = error estándar relativo):
"The relative standard deviation/error is an indicator
of the accuracy of the results obtained from the selected sample:
the smaller the RSD, the greater the accuracy of the estimation.
The RSD is usually expressed as a percentage without a [dimensional]
unit of measurement. In common practice, an RSD smaller than
or close to 10% indicates reliable sample results, although
under certain circumstances, depending on the type of phenomenon
under study, values higher than 10% may be accepted."
