GENERAL NOTES
----------------------
In some datasets, age may be calculated at a certain reference date (e.g., 31 December of last year). When the original dataset has only age categories, age is calculated as the midpoint of the range provided. In some datasets, AGE is top coded by the data provider (e.g., a value of 95 represents 95 years of age or over).
COUNTRY SPECIFIC NOTES
----------------------------------
According to the provided methodology:
98 indicates those aged 98 years or older .
99 indicates that the respondent doesn't know his/her age and the interviewer is unable to estimate the age.
Therefore, the 18 cases coded "99" were recoded "missing".
