Suspect value

Bernie over 8 years ago

I've found a very suspect value in table B01002D, column B01002D_002, which is MEDIAN AGE BY SEX (ASIAN ALONE), for Males. In Placer County, CA, census tract 210.38, block group 4 (060610210384), the value for the median age is 115+. You can check it out here: factfinder.census.gov/.../0500000US06061.15000

This is the only median age value for any geography in the country greater than 99. I'll e-mail Census, and see if they have any further information.

You know... that's what I understood (prior to this example), too, but that same table has hundreds of cells with "-" for data value, with footnote that:

"An '-' entry in the estimate column indicates that either no sample observations or too few sample observations were available to compute an estimate, or a ratio of medians cannot be calculated because one or both of the median estimates falls in the lowest interval or upper interval of an open-ended distribution."

... which *implies* some suppression is in use even in the 5 year tables.

So for this case to have passed the filtering test, there had to have been 3 observations (or more?), 2 of which were top-coded 115+.
