Note to the user
Note that the seasonally adjusted and cyclical trend numbers may be subject to revisions due to the impact of the COVID-19 health emergency. The strategy followed by INEGI is to review each time series and analyze the need to include some special treatment (outliers) in the seasonal adjustment models for the contingency months. This is so that large changes in the original data do not disproportionately affect the seasonal factors used.
