Following is a response from DHS staff member, Tom Pullum:
You can actually find MANY examples in DHS reports of what you describe for the table on page 445. Such discrepancies result from a combination of two things. First, the frequencies in almost all tables are weighted and therefore have digits to the right of the decimal point. Second, to simplify the presentation, frequencies are rounded to the nearest integer AFTER all operations such as addition.
Say, for example, that A=10.4 and B=10.3, so A+B=20.7. These 3 numbers will round to 10, 10, and 21, respectively. The discrepancy could be described as rounding error, but I don't like that term, because there's no error, just a superficial inconsistency.
