GENERAL NOTES
----------------------
In some datasets, the age may be calculated at a certain reference date (e.g., 31 December of the year preceding the survey). 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).
In some surveys, the date of birth is reported instead of reporting the age value. In such cases, it should be computed based on the date of birth and the survey year.
When the original dataset has only age categories, age is calculated as the midpoint of the range provided.
COUNTRY SPECIFIC NOTES

In few cases, large age differences were detected between the head's, the spouse's and the son's/daughter's ages.
