No help when I reviewed
census taker's instructions. I'd like to know what these numbers and alpha X means. Thank you.
Those are codes added at the Census Bureau, presumably to speed up later classification. They aren't in the instructions to the census enumerators because it was not part of what the enumerators did but added later.
See https://genealogy.stackexchange.com/questions/3257/understanding-last-three-columns-of-1910-us-census for some explanations.
You all are amazing and thank you. I was concerned it represented something important to the person.
