I believe that the Census 2010 API documentation (http://api.census.gov/data/2010/sf1/variables.html) has an error for the table: P12A. Sex By Age (White Alone).
It appears that both P012A026 and P012A049 are attributed as Female: !! 85 years and over.
I believe that P012A026 should be 'Female' (as in the total of all females.
BTW - I have *not* checked the data as of yet. The data could be correct with just the metadata incorrect.
Could someone confirm please ?
