Dear Folks,
At some point I found a document that gives the meaning of table cell values like -66666666 or -5555555 etc. Does someone know where the documentation is ? I'm using the API to download ACS tables.
Thanks,
Dave
It’s not the easiest to find, but here it is: www.census.gov/.../notes-on-acs-estimate-and-annotation-values.html
I usually look at measures by county, I run all the counties and see what percent have data (not -666666 etc.) If its less than 60 or 70% I have to see what other related measures are and what their percentage of valid numbers is. It would be great if they published all measures and what% each geo level has data.
