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
----------------------------------
The survey manual indicates that those aged less than one year of age were coded "0", and those aged 95 or older were coded "95".
