Black dots and not searched

From the user's perspective, what you see as a black dot (not born) or a black X (not searched) on the Grid are the same thing. They each just mean there is no data in that decade. Because of this, on your checks, there is no need to tell the inputter to replace black Xs with black dots. It is not worth spending the time.

We distinguish between the two as an administrative tool to help you input. Continue to use black dots and black Xs as instructed. There is just no need to write it on the checks.
